l Enter the appropriate power sensor calibration factors into the power
meter.
l Enable the power meter/sensor cal factor array. For operating information
on the HP 437B power meter refer to its operating and service manual.
l Connect the power sensor to the point where corrected power is desired.

C:onnect. 437B PM -- ENTER.
l Press (Hz/s/ENTEji) to start the calibration. The display will show each
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
of the sweeper. Power correction will be linearly interpolated between the
measured correction points. The POWER display will now.show 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 ISAVE) and then enter the number
