Frequency Response (Option B7J) Adjustment

Option B7J is a Digital Modulation Demodulation option. An electric attenuator is included in the option.

The electronic attenuator contains six attenuator sections. The sections are 1, 2, 2, 5, 10, and 20 dB steps. A maximum of 40 dB attenuation can be realized with these six sections. The electronic attenuator flatness is corrected with 101 data points from 1 MHz to 3 GHz. These correction points are not evenly spaced across the 1 MHz to 3 GHz band. The points are spaced in 15 MHz intervals in the Comms bands, and 50 MHz intervals outside the Comms bands. The same correction points are used for each of the 41 attenuator steps.

This adjustment saves an output file which lists the corrections that were stored in the instrument. The output file is saved at this location:
