Using the User Flatness

Correction Commands,

Example Program 8

The following program interrogates the synthesizer and an HP
power meter for frequency and power information respectively.
The synthesizer (an HP

is programmed to sweep from

2 to 20

with frequency-correction pairs every 100 MHz and

leveled output power. For this example, we assume that the

path losses do not exceed 5

and that the HP

power meter

already has its power sensor’s calibration factors stored in sensor
data table 0. If another power meter is used, the power sensor’s
calibration factors will have to be stored in a look-up table. Modify
the program to suit your particular measurement requirements. Up
to 801 points may be entered in the user flatness correction table
with this program.

SCPI commands are used to set up the source parameters and enter
correction frequencies and data into the correction table.
