Basic Operation

Configuring the RF Output

6.Preset either instrument.

Presetting one of the instruments should automatically preset the other as well. If both instruments do

not preset, check the GPIB connection, GPIB addresses, and ensure the 8757D is set to system interface mode (SYSINTF set to ON).

The PSG automatically activates a 2 GHz to maximum frequency ramp sweep with a constant amplitude of 0 dBm. Notice that the RF ON, SWEEP, and PULSE annunciators appear on the PSG display. The PULSE annunciator appears because the 8757D is operating in AC mode.

The PSG also switches its remote language setting to 8757D System, allowing the PSG to talk to the 8757D during ramp sweep operations. You can confirm this by pressing Utility > GPIB/RS-232 LAN and observing the selection under the Remote Language softkey.

NOTE

During swept RF output, the FREQUENCY and/or AMPLITUDE areas of the signal

 

generator’s display are deactivated, depending on what is being swept. In this case,

 

since frequency is being swept, nothing appears in the FREQUENCY area of the display.

 

 

7.Press Frequency > Freq CW.

The current continuous wave frequency setting now controls the RF output and ramp sweep is turned off.

8.Press Freq Start.

The ramp sweep settings once again control the RF output and the CW mode is turned off. Pressing any one of the softkeys Freq Start, Freq Stop, Freq Center, or Freq Span activates a ramp sweep with the current

settings.

NOTE

In a frequency ramp sweep, the start frequency must be lower than the stop frequency.

 

 

9.Adjust the settings for Freq Center and Freq Span so that the frequency response of the device under test (DUT) is clearly seen on the 8757D display.

Notice how adjusting these settings also changes the settings for the Freq Start and Freq Stop softkeys. You may need to rescale the response on the 8757D for a more accurate evaluation of the amplitude. Figure 2-3 on page 40 shows an example of a bandpass filter response.
