Intermodulation Distortion Test Setup - HP 3562A Service Manual

ODE L 3562A
n '
1 1
This test measu res the level of the intermod ulation d i stortion prod ucts generated within
2-3 2 INTERMODULATION D ISTORTION
the H P 3562A to the 4th order.
The HP 3325A may produce some spurious signals in the 0 to
1 00 kHz span. Ignore signals at frequencies other than those listed
in the tables when performing th is test.
The ampl itude of all intermodulation products will be at least 80 dB below the fu ndamental
Specifi cation
ampl itude.
