AM Internal Source Calibration
The Internal Linear/LOG mode are calibrated to ±1.0V peak external applied input. Set up equipment as
shown in
.
Test Setup
Frequency = 4 GHz
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 External source and Linear type.
2.
Connect waveform generator to the Synth AM Input and Multimeter thru a BNC-Tee.
3.
Set waveform generator to ±1.0V peak (2.0V pk-pk) and 1 kHz sinewave.
4.
Adjust amplitude until the AC voltage reading is 0.707 ±0.01V.
5.
Read “AM Meter Output”.
6.
Compute {(AM Meter Output – AM_OFFSET) / (AC voltage reading *
√
2)} + AM_OFFSET.
7.
Select AM Internal source and Linear type.
8.
Set waveform to 1 kHz sine wave.
9.
Adjust AM_REF_DAC until AM Meter Output equals value measured in
. Record the value in
.
10.
Save DAC value as AM_INT.
