PERFORMANCE TESTS
5. Set the 8642's frequency and amplitude to values listed in the
following table. Set the Spectrum Analyzer's reference level and
frequency to the values given in the following table.
6. All spurious signals must be below the level stated in the table.
NOTE
In order to obtain maximum sensitivity, this test
requires driving the input mixer of the spectrum
analyzer above its optimum level. This could cause
the generation of spurious signals in the spectrum
analyzer. If a spurious signal is observed, change the
8642's frequency. If the spurious disappears, it most
likely is from the HP 8642. If the spurious moves
with the 8642's signal, it is probably gentrated in the
spectrum analyzer.
