Creating a user flatness array
l
Zero and calibrate the power meter/sensor.
l
Enter the appropriate power sensor calibration factors into the power
meter.

correction point’s frequency and power as it is measured.
l
When the calibration is finished, the flatness correction is automatically
turned on, and the FLTNESS ON LED annunciator is lit on the front panel

measured correction points. The POWER display will the test
port power.
Attention!
Before doing anything else, save this calibration in one of the instrument’s registers. If the calibration
has not been saved, and the instrument is preset, a register is recalled, or the power offset is
changed, the calibration will be lost. To save the calibration, press and then enter the number
of the instrument register you wish to save it in.
