Basic Operation

Configuring the RF Output

5.Press the Trigger hardkey.

The signal generator will single sweep the points in your list and the SWEEP annunciator will be activated during the sweep.

To Configure a Continuous List Sweep

Press Sweep Repeat Single Cont.

This toggles the sweep from single to continuous. A continuous repetition of the frequencies and amplitudes configured in the list sweep are now available at the RF OUTPUT connector. The SWEEP annunciator appears on the display, indicating that the signal generator is sweeping and progression of the sweep is shown by a progress bar.

Using Ramp Sweep (Option 007)

Ramp sweep provides a linear progression through the start- to- stop frequency and/or amplitude values. Ramp sweep is much faster than step or list sweep, and is designed to work with an

8757D Scalar Network Analyzer. This section describes the ramp sweep capabilities available in PSG signal generators with Option 007. You will learn how to use basic ramp sweep, and how to configure a ramp sweep for a master/slave setup (see page 50).

Refer to the E8257D/67D PSG Signal Generators Programming Guide for an example program that uses pass- thru commands in a ramp sweep system (pass- thru commands enable you to temporarily interrupt ramp sweep system interaction so that you can send operating instructions to the PSG).

Configuring a Frequency Sweep

1. Set up the equipment as shown in Figure 2- 2.

NOTE The PSG signal generator is not compatible with the GPIB system interface of an 8757A, 8757C, or 8757E. For these older scalar network analyzers, do not connect the GPIB cable in Figure 2- 2. This method provides only a subset of 8757D functionality. See the PSG Data Sheet for details. Use the 8757A/C/E documentation instead of this procedure.
