Specifications
Residual Amplitude Modulation (AM)
Less than 0.05% AM rms for input levels above 100
mV rms.
Less than 0.15% AM rms for input levels from 30 mV
to 100 mV rms.
Less than 0.45% AM rms for input levels from 10 mV
to 30 mV rms.
NOTE
Frequency
less
than
500
MHz,
measurement bandwidth 30 Hz to 15 kHz.
Above 500 MHz, residuals increase linearly
with frequency.
Frequency Modulation (FM) Rejection
Less than 0.5% AM at 50 kHz deviation
(modulating frequency less than 100 kHz).
f
Depth Accuracy
0.7% of reading at 20%, 30%, and 40% AM; mod
30 Hz to 3 kHz; filter, 10 Hz to 15 kHz.
Detector Flatness
Indicated AM within 0.4% for constant % AM
f
between 20% and 40% and mod of 90 to 150 Hz.

Shape Factor
All filters except 10 Hz and 200 kHz are three-pole
Butterworth; de-emphasis time constant and 3 dB
filter frequencies have accuracy of 4% (except 10
Hz).
