Analog Measurements

AC Control

The type of measurement shown is dependent on the AF Anl In settings. AC Level is displayed when the AF Anl In field is set to SSB Demod, Audio In, Ext Mod, or Audio Out.

The AC Level measurement field displays either rms potential (voltage) or audio power (Watts or dBm).

See “Displaying AF Measurements” on page 57, or “AF Anl In” on page 185 for more information.

AM Depth Measurement

This measurement field displays the percent depth of modulation of the AM signal. This measurement is displayed when the AF Anl In field is set to AM MOD or AM DEMOD.

See “Displaying AF Measurements” on page 57, or “AF Anl In” on page 185 for more information.
