Making a Power Measurement using
Broadband Detection
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
for a narrowband detection power measurement. A narrowband
detection 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 all 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.
NOTE
Broadband power measurements are only specified for measurements
with a start frequency of
≥
10 MHz.

NOTE
This example measurement uses the default instrument parameters for
a power measurement. If your particular power measurement requires
different parameters (such as source power level, number of data points,
and sweep time), enter them now.
