2.Turn on both the 8757D and the PSG.

3.On the 8757D, press System > More > Sweep Mode and verify that the SYSINTF softkey is set to ON.

This ensures that the system interface mode is activated on the 8757D. The system interface mode enables the instruments to work as a system.

4.Press Utility > GPIB/RS-232 LAN to view the PSG’s GPIB address under the GPIB Address softkey. If you

want to change it, press GPIB Address and change the value.

5.On the 8757D, press LOCAL > SWEEPER and check the GPIB address. If it does not match that of the PSG, change the value.

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.
