Making A Power Measurement Using Broadband Detection - HP 8711C User Manual

Power measurements can be made using either narrowband or broadband
detection. The example in this section is of a broadband power measurement.
If you are only interested in the output power of your device at the
same frequency as the analyzer's source, you can select (MEAS]
Detection Options Narrowband Internal B for a narrowband power
measurement. A narrowband power measurement only measures the power
within the tuned receiver's bandwidth centered at the source frequency.
When you measure a device for absolute output power, the network analyzer
uses the broadband detection mode and measures the total power of ah
frequencies present in the transmitted signal (B*). This signal may contain
frequencies other than the source frequency such as when the DUT is a
mixer.
This section uses an example measurement to describe how to normalize the
data and measure the total output power of an amplifier.
