Description
Less than 3 Hz peak-to-peak for sweep time 510 s; span ~100 kHz;
resolution bandwidth 530 Hz, video bandwidth 530 Hz.
Residual FM Test
A signal source is connected to the spectrum analyzer input and
the required front panel control settings are made as stated in
the specification. The slope of the signal is measured for use in
calculating the residual FM. The signal is centered on the display and
the peak-to-peak amplitude deviation of the signal measured. The
frequency deviation is the result of the amplitude deviation being
divided by the slope (measured earlier in the test).
