the oscillator to 0 dBm at the desired frequency.
Then set the MEAS-CAL
switch to MEAS without making further adjustments.
Record the level
indicated on the voltmeter in the Input level column of the test data sheet.
NOTE:
It must be understood that the changes in apparent level
during this test do not change the validity of the test,
but indicate an impedance mismatch which may be the cause
of the frequency response being out of tolerance.
The
terminal impedance test will confirm this.
