Where Vs is the output voltage of the signal source before the output impedance Rs. Since thesignal source cannot automatically identify the value of RL, the user needs to inform the signal
source of the value by inputting the "load" value, and then the signal source calculates the Vs
according to the RL and Vo set by the user so that the Vo obtained by the user is consistent withthe expected value under any load.

Waveform Parameters
The parameters that can be set for each standard wave are different, as shown in the table below:

Offset/Low level

The amplitude/offset of the signal is linked with the High level/Low
level. Amplitude value refers to the difference between the highest

the signal. The supported units include Vpp, Vrms, and dBm(available when the load ≠ HiZ).
Offset refers to the DC component superimposed on the signal
waveform, in V.

Arbitrary Waveform Setting

Arbitrary waveform provides two modes: AFG and AWG. On the parameter setting page where
the carrier is an arbitrary waveform, click the value area of the "Mode" parameter setting box toselect the required mode:

9.5.1 AFG Mode
In AFG mode, the signal generator outputs the specified arbitrary waveform in the way of
traditional Direct Digital Synthesis (DDS) generators. At this time, the basic waveform parametersetting is the same as that of the sine wave. Refer to the section "Standard Waveform Setting".
For data source selection and editing of an arbitrary wave, refer to the section "Data Source".

9.5.2 AWG Mode
In AWG mode, the signal generator employs SIGLENT’s TrueArb Technology (Figure 9-2) andoutputs the specified waveform sequence point-by-point with a user-specified sample rate.
TrueArb overcomes the intrinsic defects of traditional DDS technology that may increase jitterand distortion when generating arbitrary waves, while retaining its advantages of low cost,
simplicity and flexibility.

The arbitrary waveform editing software EasyWaveX provides 11 standard waveforms such assine, square, ramp, pulse, noise, and DC, which can meet the most basic needs. It also provides
users with manual drawing, line drawing (including horizontal line, vertical line, and two-pointline), coordinate drawing (coordinates can be input through mouse or table, and there are two
ways of connecting line and smoothing) and equation drawing, which makes it easy to create
complex waveforms.
SDG7000A not only supports the waveforms issued by EasyWaveX software running on the PC
but also integrates EasyWaveX into the device as a built-in application so that it supports editing
and saving waveforms directly on the device. When "EasyWaveX" is selected as the data source,
the EasyWaveX software will be automatically run on the device:

10.2.1 Source Selection
There are 3 types of sources for modulating signals: Internal, external, and channel. A detailed
description is given in the following table.
Table 10-1 Modulated waveform sources and descriptions

SourceDescription

Internal

The modulation signal is generated internally from the DDS module according
to the user's configuration (modulation frequency, modulation waveform), etc.
The modulation signal is external.
When the modulation type is analog modulation (AMB/DSB-SC/FM/PM/PWMetc.), the external source is fed from the external modulation interface on therear panel. The amplitude of the input analog signal determines the modulation
factor (modulation depth/frequency deviation /phase deviation etc.).

External

The requirements for the external modulation amplitude are described in detailin the datasheet parameter "Amplitude at 100% modulation". See Table 10.2 fora description of the 100% modulation.
When the modulation type is digital keying modulation (ASK/FSK/PSK etc.), theexternal source is input from the trigger interface on the rear panel.
The input digital sequence must meet the electrical requirements of the trigger
input (see datasheet for details)

ChannelWhen the carrier is CH1, CH2 can be directly used as the modulating waveform.
In this case, the device directly uses CH2 to modulate CH1 internally without
introducing the waveform of CH2 to the external modulation interface throughan external cable. Vice versa.

Table 10-2 Description of 100% modulation

Description
AM

Corresponds to the case where modulation depth = 100%

FM

100% modulation is equal to the set frequency deviation. For example, if theamplitude of the external modulation input is 50% of the corresponding
amplitude when 100% modulation is selected, the resulting frequency deviation
is 50% of the set frequency deviation.

PM

100% modulation is equal to the set phase deviation. For example, if theamplitude of the external modulation input is 50% of the corresponding
amplitude when 100% modulation is selected, the resulting phase deviation is
50% of the set phase deviation.

The shape of the modulating waveform.
When source = internal, the value can be set directly. When source =external or channel, it is determined by the external modulation input or
the waveform of another channel.

The AM amplitude strategy is to keep the power of the carrier the same as when it is unmodulated,
i.e.: the power of the carrier is independent of the modulation depth. This will result in the AM
waveform peaking beyond the set value, which is normal. The figure below shows a comparisonof the amplitude of a 100 MHz, 0 dBm carrier with no modulation and at 100% modulation depth,
and it can be seen that the peaks in the time domain become larger when modulation is turned
on, but the power of the carrier remains the same in the frequency domain.

12 Dual Channel Setup
12.1 Overview
The SDG7000A features enhanced dual channel functionality. With two phase modes, the unit
can be used as two independent signal generators, or the two channels can be output
synchronously. The ability to track, copy, and couple between the two channels ensures thatparameters from one channel are quickly transferred to the other as required, greatly simplifying
operation and meeting the need for fast, simultaneous waveform switching. The ability to
combine two waveforms and output them in real-time, with the ability to superimpose true noise,
modulated signals, sweep signals, burst signals, EasyPulse waveforms, and TrueArb waveforms,
provides users with a new means of accurately generating complex waveforms.

Click on Dual Channel in the toolbar on the home page to access the settings related to Dual
Channel.

SDG7000A User Manual

12.2 Phase Mode
The SDG7000A supports two phase modes.
Independent mode: Two channels can be used as two independent signal
generators, setting one channel does not affect the output of the otherchannelLocked mode: Synchronous output of both channels, initially phase-aligned
and ensuring that they are phase-locked when the frequencies are integer
multiples of each other, with no drift

In "Independent" mode, the two channels can be used as two independent signal generators,
and setting one channel will not affect the output of the other channel.
In "Locked" mode, setting the time parameter of either channel will force the two channels toreset to ensure that they are phase aligned. In addition, the frequency calculation of the channels
is specially handled in "Locked" mode to ensure that the two channels are phase-locked when
the frequencies are integer multiples of each other and do not drift.
DDS (Direct Digital Synthesis) technology has the advantage of high-frequency resolution andfast frequency switching compared to PLL (Phase Locked Loop) technology. However, DDS isan open-loop system and does not allow for true 'locking' between input and output in the same
way as a phase-locked loop, i.e. the input and output of a DDS structure may not be phaselocked and the output may drift in phase when viewed over long time durations.
As an example, set CH1 to output a 1 MHz frequency clock and CH2 to output a 10 MHz
frequency clock, according to the relationship between the DDS frequency control word (FTW)
and the output frequency fout.

f out FTW
= N
FDDS
2
With the DDS operating frequency FDDS = 2.5 GHz and the bit width of the frequency control
word N = 52, the actual output frequencies and frequency errors for both channels can becalculated as shown in the table below. The error is introduced by the rounding of the frequency
control word. As the FTW is passed to the DDS circuit as a fixed-point integer, an error isinevitably introduced between the theoretical and actual value of the FTW.

As we can see from the table above, the frequency errors introduced on both channels are small,but not proportional, which results in the two frequencies that were integer multiples no longer
being integer multiples, with the result that they are not phase-locked. The following is the phasedrift (approximately 6.9 ns) observed in this example after 17.3 hours for both channels in“Independent” mode.

In “Lock” mode, the unit forces the higher frequency FTW to be an integer multiple of the lower
frequency FTW for frequencies that are an integer multiple of each other, which may increase
the output error at the higher frequency but ensures phase lock between the two. In this example,
the outputs of the two channels in "Locked" mode are observed over a long period. As we cansee, the phases are always aligned.

Set "Waveform" of the carrier to "Sine", "Frequency" to 1 MHz and "Amplitude" to 1
Vrms in the parameter setting page of CH1.

2.

According to Signal to noise ratio 20 dB, converted to a signal to noise amplitude
ratio (s/σ) of 10:1. from signal amplitude s = 1 Vrms gives noise amplitude σ = 100

12.4 Channel Tracking/Coupling/Copy
Channel track/coupling/copy can be set up under the 'Dual-Channel Setting' page. The ability
to track, copy, and couple between two channels ensures that parameters from one channel
are quickly transferred to the other as required, greatly simplifying operation and meeting theneed for fast, simultaneous waveform switching.
Table 12-2 Description of channel tracking/coupling/copy

Type of operation

Description

Track

The parameters of the two channels are fully synchronized and theparameters set for one channel are automatically passed to the otherchannel, where the two channels are duplicates of each other.
In tracking mode, the device will force the phase mode to "Locked" andonly allow the setting of CH1.

Coupling

The parameters of the two channels are coupled in a certain relationshipwith CH1 as reference so that the parameters of one channel areautomatically converted and passed to the other channel according to
the coupling relationship.
The coupling parameters that can be set are frequency, amplitude, andphase, and the coupling relationship can be proportional or deviated.

Copy

Manually copy parameters from one channel to another. Changing theparameters of one channel after that will not cause the parameters ofanother channel to change.

Application example: Use the channel copy function and the waveform combinefunction to generate a two-tone signal at frequencies 10 MHz and 10.1 MHz.

The above steps are followed to generate the desired signal. The output is as followed (the red
trace is the signal without noise, while the green trace is the signal with noise) and is consistent
with the results of the previous example.

13.4 Amplitude Limit
In some applications, the user needs to limit the amplitude of the channel output to ensure that
amplitude sensitive signal receiving device is not damaged. Click on the setting iconin the"Amplitude Limit" parameter box to access the Amplitude Limit.

The default maximum amplitude is the maximum amplitude that the device can provide, see thedatasheet for details.

13.5 Digital Filtering
A 32-tap FIR digital filter is integrated into each channel to support low-pass filtering, with asettable cut-off frequency. This allows the user to limit the bandwidth of the output signal.

Application example: generate a pulse signal with 1 ns edges and set theoutput filter to 100 MHz, then compare the change in the edges when the
output filter is turned on and off

1.

In the parameter setting page of the carrier, set "Waveform" to "Pulse", "Frequency"
to 1 MHz, "Load "50 Ω, "Amplitude" to 1 Vpp, "Duty Cycle" to 50%, and "Rising Edge"
to 1 ns.

2.

Under the "Output1 filter" settings page, set "Cut-off frequency" to 100 MHz.

3.

Observe the results without opening the Output1 filter; open the Output1 filter andobserve the results again.

The output results are compared below. The measured rising edge without the output filter isaround 0.94 ns, which roughly complies with the setting, and the measured rising edge with theoutput filter on is around 3.6 ns, which roughly complies with the 100 MHz bandwidth.

13.6 Output Protection
The output protection consists of over-voltage protection (OVP) and over-current protection(OCP). OVP and OCP switches are shared by both outputs. Separate control of OVP or OCP
for both channels is not supported.

13.7 Single-ended/Differential Settings
The unit offers two output modes, single-ended and differential. They can be set directly in the"Output Settings" page.

The output terminals on the front panel are "+" on the right and "-" on the left when the output isdifferential, and "+" on the left when the output is single-ended.
The analog parameters will differ between the single-ended and differential output modes, asdetailed in the datasheet.
After the output is set to "Differential", a parameter setting box for "Common Mode" will appear
on the carrier settings page, providing an entry for setting the common mode of the differential
signal, as shown below:

Note the distinction between the concepts of "Common Mode" and "Offset". Both are DC levels,
but "Common Mode" refers to the common-mode component of the differential pair, while"Offset" is the differential mode component.
With "differential" output, the "amplitude" of the signal refers to the peak-to-peak value of thedifferential mode signal, i.e.:

Vpp = ( V+ − V− )pk − pk
It is related to the peak-to-peak value of the signal on the "+" or "-" alone by a factor of 2.

The SDG7000A provides 16 digital signal outputs. The digital output function is available withthe optional digital output kit. There are two digital levels to choose from: LVTTL and LVDS. The
LVTTL kit output converts the LVDS signal output by the device into LVTTL signals and outputs
it. Since the level conversion requires a special chip, the kit needs an external USB power supply.
The kit providing LVDS output directly leads out the LVDS signal of the device without an external

2.

Set one of the devices as "Master" and the other devices as "Slave".

3.

Connect the [TRIG/SYNC] of the master to the [TRIG/SYNC] of other slaves respectively.

4.

Connect the [10MHz Out] connector of the Master to the [10MHz In] connector of the first
Slave, and then connect the [10MHz Out] connector of the first Slave to the [10MHz In]
connector of the second slave, etc.

5.

Set the same output frequency for all the generators.

6.

Press the "Sync Device" button on the Master to apply synchronization.

Figure 17-1 wiring diagram of multi-device synchronization

The synchronous signal is transmitted from [TRIG/SYNC] of the Master to [TRIG/SYNC] of the
Slave(s) through the BNC cable when Sync Devices is pressed. There is a certain delay between
the moment when the master sends the synchronous signal and the moment when the Slave(s)receive it. Therefore, the output waveforms from different generators will have a certain phasedifference related to the BNC cable. Users can adjust the phase of every Slave independently tocompensate for the phase difference.
