Frequency Offset Using Power Sensor (FOPS) (Option 208) unique commands

 

See Also: Example Program


Perform Normalization

There is NO unique FOPS command to MEASURE the source power.

Instead, use the following method:

  1. Prompt to connect the power sensor to port 1 RF Output reference plane.

  2. Send  INIT:CONT 0

  3. Send INITiate[:IMMediate]

  4. Send SOURce:POWer:MEMorize to store the data trace to memory.

  5. Send [:SENSe]:TRACe:MEASurement to display your measurement choice.
