Swept mm-wave Measurement with Arbitrary Correction Frequencies,
Example 3
The focus of this example is to use user flatness correction to
obtain flat power at the output of the HP 83550 series mm-wave
source modules. In this case we will use non-sequential correction
frequencies in a swept 26.5 to 40 GHz measurement with an
HP 83554 source module.
The time it takes for a large quantity of power meter measurements
can be long, therefore, we selected non-sequential correction
frequencies to target specific points or sections of the measurement
range that we assume are more sensitive to power variations. This
greatly expedites setting up the user flatness correction table. The
amount of interpolated correction points between non- sequential
correction frequencies varies. This example uses
theHP
437B
to
automatically enter correction data into the array.
Note
Turn off the synthesizer before connecting to the source module
interface (SMI)
cable, or damage may result.
