Optimizing Performance

Creating and Applying User Flatness Correction

Figure 3-6 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.
