AM Depth Indicator Settings
Ext Linear Mode
AM Depth % = User defined Sensitivity %/V * [(AM Meter Output – AM_OFFSET) * AM_METER / 10000]
Ext LOG Mode
AM Depth dB = User defined Sensitivity dB/V * [(AM Meter Output – AM_OFFSET) * AM_METER / 10000]
AM Internal Source Verification (Linear Mode)
Test Setup
Frequency = 25 MHz
Power Level = 6 dB below max specified leveled output power (Config and Freq dependent)
Atten mode = Atten Auto
Test Procedure
1.
Turn AM On. Select AM Internal source and Linear type.
2.
Set Waveform to 1 kHz sine wave.
3.
Set AM_REF_DAC to AM_INT.
4.
Set AM_CAL_DAC to AM_CAL_LIN_25M.
5.
Set AM_SEN_DAC to AM_SEN_LIN_25M.
6.
Measure first sideband suppression by taking averages of upper and lower sidebands in dBc.
7.
Compute Mod Depth % using 2 * 10^(sideband suppression / 20). Record value in
.
8.
Repeat measurement with Freq.
9.
Repeat at 1G / 4G / 10G / 20G / 40 GHz with corresponding Power Level and DAC name.
10.
Compare computed and theoretical Mod Depth. Pass if all absolute difference are
≤
±4 %.
