6.Press the More (1 of 2) softkey.

From this softkey menu, select the bit order, swap I and Q, the polarity of the data, and access menus that provides data negation, scaling, and filtering parameters.

7.Press the Data Negation softkey.

Negation differs from changing the I and Q polarity. Applied to a sample, negation changes the affected sample by expressing it in the two's complement form, multiplying it by negative one, and converting the sample back to the selected numeric format. This can be done for I samples, Q samples, or both.

The choice to use negation is dependent on the device being tested.

8.To access I/Q scaling and filter parameters, press Return > N5102A Off On to On. This will invoke the real time Custom format in the PSG baseband generator. This is needed to set the filter parameters when Pre- FIR Samples is selected as the data type.

9.Press the Baseband Setup softkey.

Use this softkey menu to adjust the I/Q scaling and access filter parameters. If the selected data type is Samples, the Filter softkey is grayed out (inactive).

Digital Data

If the N5102A digital module is not on, press Return > Return > N5102A Off On to On.

Digital data is now being transferred through the N5102A module to the PSG. The green status light should be blinking. This indicates that the data lines are active. If the status light is solidly illuminated (not blinking), all the data lines are inactive. The status light comes on and stays on (blinking or solid) after the first time the N5102A module is turned on (N5102A Off On softkey to On). The status light will stay on until the module is disconnected from its power supply.

NOTE If changes are made to the baseband data parameters, it is recommended that you first disable the digital output (N5102A Off On softkey to Off) to avoid exposing the device and the N5102A module to the signal variations that may occur during the parameter changes.

Millimeter-Wave Source Modules

You can extend the signal generator’s RF frequency using an Agilent 8355x series millimeter- wave source module or any other external source module. The output frequency range depends on the frequency range of the mm- wave source module. This section contains the following procedures:

•Using Agilent Millimeter- Wave Source Modules

•Using Other Source Modules

Using Agilent Millimeter-Wave Source Modules

The Agilent 8355x series millimeter- wave source module connects to the signal generator’s rear panel SOURCE MODULE INTERFACE connector and allows for direct communication between the instruments as well as providing for automatic leveling control of the source module. If you want to use an 8355x series source module without the automatic leveling or multiplier selection features, then refer to the section “Using Other Source Modules” on page 240.
