Operating Concepts
Knowing the Instrument Modes
relative power of the measured harmonic in dBc. You must uncouple channels 1 and 2 for this measurement,

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).
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 8753ET/ES Option 006.

Accuracy and Input Power
Refer to the 8753ES and the 8753ET specifications and characteristics chapters of the reference guide for
recommendations on the maximum recommended input power and maximum source power.
Using power levels greater than the recommended values 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.
