Basic Operation

Configuring the RF Output

3.Press Sweep Time to Manual > 5 > sec.

In auto mode, the sweep time automatically sets to the fastest allowable value. In manual mode, you can select any sweep time slower than the fastest allowable. The fastest allowable sweep time is dependent on the number of trace points and channels being used on the 8757D and the frequency span.

4.Press Sweep Time to Auto.

The sweep time returns to its fastest allowable setting.

Using Alternate Sweep

1.Press the Save hardkey.

This opens the table editor and softkey menu for saving instrument states. Notice that the Select Reg softkey is active. (For more information on saving instrument states refer to “Using the Instrument State Register” on page 54.)

2.Turn the front panel knob until you find an available register and press SAVE. Remember this saved register number. If no registers are available, you can write over an in-useregister, by pressing Re-SAVE.

NOTE

When you are using the PSG in a system with an 8757 network analyzer, you are limited to

 

using registers 1 through 9 in sequence 0 for saving and recalling states.

 

 

3.Press Sweep/List > Configure Ramp/Step Sweep and enter new start and stop frequency values for the ramp sweep.

4.Press Alternate Sweep Register and turn the front panel knob to select the register number of the previously saved sweep state.

5.Press Alternate Sweep Off On to On.

The signal generator alternates between the original saved sweep and the current sweep. You may need to adjust 8757D settings to effectively view both sweeps, such as setting channel 2 to measure sensor A. Refer to Figure 2-6.
