TUNING ACCURACY
SPECIFICATION:

(5 MHz
3.0 21.0 GHz:
-
DESCRIPTION:
An external RF source is used to provide a frequency-calibrated input signal to the spectrum analyzer for three
points on each frequency band. The digital FREQUENCY GHz readout is compared with the known test
frequency to find the amount of readout (or tuning) error. The 10 dB attenuator is necessary to reduce LO
emission from the spectrum analyzer to the frequency counter when using the sweep oscillator.

The HP 8350A Sweep Oscillator may be substituted for the HP 8620C in this
procedure.
