Millimeter-Wave Source Modules
When the 8355x series mm-wave source is enable via the front panel Agilent 8355x Source
Module Off On softkey, the MMOD indicator in the FREQUENCY area and the MM indicator in the
AMPLITUDE area will appear on the signal generator’s display.
3. If the RF OFF annunciator is displayed, press
RF On/Off.
Leveled power should be available at the output of the millimeter-wave source module.
To obtain flatness-corrected power, refer to “Creating and Applying User Flatness Correction” on
page 123.
Using Other Source Modules
Use the following procedure to extend the frequency range of the PSG with any external source
module, or to use the Agilent 8355x series millimeter-wave source module’s without automatic
leveling. The following is a list of equipment required for extending the frequency range of the signal
generator:
• external millimeter-wave source module
• Agilent 8349B or other microwave amplifier (required only for the E8257D PSG without
Option 1EA)
• RF output cables and adapters as required
Setting Up the External Source Module
1. Turn off the signal generator’s line power.
2. Connect the equipment as shown.
• E8257D PSG without Option 1EA uses the setup in Figure 11-23.
• E8257D PSG with Option 1EA or E8267D PSG uses the setup in Figure 11-24.
