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.
