Figure 4-6 User Flatness with mm-Wave Source Module and Option 1EA Signal Generator
NOTE To ensure adequate RF amplitude at the mm-wave source module RF input when using
Option 1EA signal generators, maximum amplitude loss through the adapters and cables
connected between the signal generator’s RF output and the mm-wave source module’s RF
input should be less than 1.5 dB.
Configure the Signal Generator
1. Turn on the signal generator’s line power. At power-up, the signal generator automatically does
the following:
• senses the mm-wave source module
• switches the signal generator’s leveling mode to external/source module
• sets the mm-wave source module frequency and amplitude to the source module’s preset
values
• displays the RF output frequency and amplitude available at the mm-wave source module
output
The MMMOD indicator in the FREQUENCY area and the MM indicator in the AMPLITUDE area of the
signal generator’s display indicate that the mm-wave source module is active
NOTE For specific frequency/amplitude ranges, see the mm-wave source module specifications.
