2.2 LevelSetting
The value of the RF level is displayed in the level text field locatedin the header of thedisplay (labeled―Level‖).This field provides the direct input of

the RFlevel

value .Alternatively, you can enter the level in the level dialog.

Note that the displayed RF level in the header, and the RF output level, set in the ―Level‖
dialog can be different, as explained in the following section.

If you working with a downstream instrument, e.g. an attenuator or amplifier, you can enter
the level offset value in the settings dialog (labeled ―Level Offset‖).

The generator includes these parameters and displays the result in the ―Level‖ field in thestatus bar, as if the downstream source and the generator were one unit. This displayed
level value corresponds to the value at the RF output of the instrument and any
downstream sources. . However, the level provided at the RF output of the signal
generator corresponds to the level value set in the ―Level Setting‖ dialog.

When a level offset is enabled, the instrument display changes the color of ―OFFSET―from grey to blue.

When the ―Int‖ modulation source is selected, the AM modulation depth is set from 0.01%
to 100%. The relationship between the modulation depth m and the carrier sideband level
difference ΔP is satisfied: ΔP=6.02-20*log (m)When the ―Ext‖ modulation source is selected, the sensitivity of the external modulation
source level amplitude to the modulation depth is 50%/V. For example, the modulation
depth is 100% when the external modulation signal is 2Vpp (offset is 0V), and themodulation depth is 50% when the external modulation signal is 1Vpp (offset is 0V).

When selecting the ―Int+Ext‖ modulation source, the modulation depth set is the internalsource modulation depth + the external source modulation depth, and the internal source
modulation depth is assigned = the external source modulation depth. For example, if themodulation depth is set to 100%, the modulation depth assigned to the internal source is50%, the external source modulation depth is 50%, and the external modulation sensitivity
is 25%/V. If the external modulation signal is 2Vpp (the offset is 0V), then the modulation
depth is 100%.

2.7.2 Level Control

As shown in the example, the sensor measures a proportional power in defined timeintervals, derived from a coupler. It considers optionally the given S-parameters andreturns the results to the generator. The signal generator compares the measured levelwith the set value and adjusts its output level accordingly.This allows you to control theexternal signal level continuously and reliably reach a constant input level at the DUT inreal time.

In practice, an RF splitter is needed to split the RF signal.One of them is connected to the
DUT and the other is connected to the power meter. The signal source is for acquisitionand compensation.Power compensation can be used to minimize cable losses, theattenuation of passive networks, and the amplification of the signal by a power amplifier
and the frequency response of each device in the link as the frequency changes.

Note: When the function is turned on, the frequency or level sweep and the power sensor
measurement function will be turned off, and vice versa.

Target Level

Specify the nominal level expected at the input of the sensor. The signal generator adjusts

The value can be set by the touch screen keyboard or the front panel keypad.

Capture Range

The capture range means that if the power sensor reading is within the effective capture
range, it is a valid reading and the RF signal is adjusted and compensated. Set thecapture range of the control system.If the power sensor reading exceeds this range, thereading will be ignored.

Note: Only some models are equipped with IQ modulation function. For specific models,please refer to the SSG3000X data sheet.

2.8.1 Turning on I/Q modulation
The I/Q modulation setup menu can be accessed in one of three ways:
Click the Power Meter button on the shortcut menu page.



Click the I/Q modulation control on the home page.



Press the I/Q button on the front panel.

On the I/Q modulation interface, click on the I/Q status to turn on I/Q modulation.

2.8.2 I/Q source
The I/Q modulation uses an external modulation source that receives the I/Q modulated
in-phase baseband signals and quadrature phase modulation signals input from the [IINPUT] and [Q INPUT] connectors on the rear panel.

Note: The modulation function must be activated to modulate the output signal. You canturn it on or off by pressing the MOD ON/OFF button or you can open it by checking the
MOD module on the home page.
