To Set the Pulse Width/DutyCycle
Pulse width is defined as the time from the 50% threshold of a rising edge
amplitude to the 50% threshold of the next falling edge amplitude (as shown in
the figure below). The pulse width setting range is limited by the “Minimum
Pulse Width” and “Pulse Period” setting. For detailed information, please refer
to “SDG6000X Datasheet”. The default value is 200 μs.

Pulse duty cycle is defined as the percentage that the pulse width takes up in
the whole period. Pulse duty cycle and pulse width are correlative. Once aparameter is changed, the other will be automatically changed.

Press Waveforms→ Pulse → PulWidth, to set the pulse width parameter.
When changing parameter, if the new value is valid, the value will be set.

2.2 Harmonic Function
The SDG6000X can be used as a harmonic generator to output harmonics
with specified order, amplitude and phase values. According to the Fouriertransform, a periodic time domain waveform is the superposition of a series ofsine waveforms as shown in the equation below:

Generally, the component with the frequency term f1 is called the fundamental
waveform, where A1 is the fundamental waveform amplitude, and φ1 is thefundamental waveform phase. The frequencies of the other components(harmonics) are all integral multiples of the fundamental waveform.
Components whose frequencies are odd multiples of the fundamental
waveform frequency are called odd harmonics and components whose
frequencies are even multiples of the fundamental waveform frequency arecalled even harmonics.

Load
For the [CH1] and [CH2] connectors on the front panel, the generator always
has an output impedance of 50Ω, but the instrument features a load settingthat is used to adjust the displayed amplitude setpoint based on the expected
external load impedance. If the actual load does not match the set load, thedisplayed voltage will not be the same as the output voltage. This function isused to match the displayed voltage with the expected one. This setting does
SDG6000X User Manual125not actually change the output impedance to any other value.
Press Utility → Output Setup → Load, to select “HighZ” or “50Ω”, or use thenumeric keyboard to set a specific impedance value. The available range isfrom 50 Ω to 100 kΩ. The default is “HighZ”.
⚫

Pressing the corresponding output key for two seconds will switch
between High Impedance and 50Ω

⚫

The generator will adjust the output amplitude and offset voltage
automatically once the load setting is changed. For example, if theamplitude is set to “5 Vpp” with the load impedance set to “50 Ω”, it willchange to display “10 Vpp” when the impedance is changed to “HighZ”.
If the load is changed from “HighZ” to “50 Ω”, the displayed amplitude will
be reduced half of the previous value. Only the displayed values changewith the parameter. The generator output impedance does not change.

⚫

If load is set as “HighZ”, the amplitude units cannot be set as “dBm”

Polarity
Press Utility → Output Setup → Polarity to set the output signal as normal or
inverted. The waveform’s inversion is relative to the 0v offset voltage, as

The SDG6000X supports frequency, amplitude and phase coupling. Users can
set the frequency deviation/ratio, amplitude deviation/ratio or phase deviation/ratio of the two channels. When coupling is enabled, CH1 and CH2 can be
modified simultaneously. When the frequency, amplitude or phase of one
channel (as the reference) is changed, the corresponding parameter of theother channel will be changed automatically and always keeps the specified
frequency deviation/ratio, amplitude deviation/ratio or phase deviation /ratio
relative to the base channel.

Key Points:
1. Channel coupling is only available when both the waveforms of the twochannels are basic waveforms including: Sine, Square, Ramp, Arbitraryand PRBS.
2. When the Phase Coupling function is enabled, if the phase of one channel
is changed, the phase of the other channel will be changed accordingly. At
this point, aligning phase between the two channels can be achieved
without executing the Eqphase operation.
