FM Discriminator Measurement Examples
6
Choose the Sources tab from the Define Measurement window.
a
Enter the carrier (center) frequency of your DUT (5 MHz to
1.6 Gaze). Enter the same frequency for the detector input frequency.
See Figure 184.
7
Choose the Cal tab from the Define Measurement window.
a
Select Derive constant from double-sided spur as the calibration
method.
b
Feed the output from a modulated calibration source into a spectrum
analyzer and measure the 1st modulation sideband frequency and power
relative to the carrier’s frequency and power. Enter the parameters in
the following step.
c
Set the Know Spur Parameters Offset Frequency and Amplitude for
the spur you plan to use for calibration purposes.This calibration
method requires that you enter the offset and amplitude for a known
spur. See Figure 185 on page 257.
