Accuracy And Input Power - HP 8753E User Manual

Coupling Power Between Channels 1 and 2
the fundamental on channel 1 and the harmonic on channel 2. D2/Dl to D2 ratios the two,
showing the fundamental and the relative power of the measured harmonic in dBc You must
to OFF to allow alternating sweeps.
After uncoupling channels 1 and 2, you may want to change,the fundamental power and see
the resultant change in relative harmonic power (in dBc). .~~~~~.~~~~~~~~~~~~~ allows you to
change the power of both channels simultaneously, even though they are uncoupled in all other
respects.
Frequency Range
The frequency range is determined by the upper frequency range of the instrument or system
(3 or 6 GHz) and by the harmonic being displayed. The 6 GHz operation requires an HP 87533
Option 006. Table 6-9 shows the highest fundamental frequency for maximum frequency and
harmonic mode.

Accuracy and input power

Refer to Chapter 7, "Specifications and Measurement Uncertainties. n The maxims
recommended input power and maximum recommended source power are related
specifications.
Using power levels greater than the recommended values, you may cause undesired harmonics
in the source and receiver. The recommended power levels ensure that these harmonics are
less than 45 dBc Use test port power to limit the input power to your test device.
