HP 8360 L Series User Manual

Using the User Flatness
The following program interrogates the swept CW generator and
Correction Commands,
an HP 437B power meter for frequency and power information
Example Program 8
respectively. The swept CW generator is programmed to sweep from
2 to 20 GHz, with frequency-correction pairs every 100 MHz and
+5 dBm leveled output power. For this example, we assume that the
path losses do not exceed 5 dBm and that the HP 437B 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 ‘co 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.
