Calibration Procedures
Turn on the Agilent 53147A/48A/49A and then wait for at least
30 minutes to allow the internal temperature of the instrument
to stabilize.
Connect an Agilent E9635A adapter to the Power Meter OUTPUT connector
as shown in Figure 2-2.
Connect an Agilent 10503 series cable from the Agilent E9635A adapter
on the Agilent 53147A/148A/149A's Power Meter OUTPUT connector to
the CHANNEL 1 input connector on the Agilent 53150A/51A/52A
Frequency Counter.
Set the Agilent 53150A/51A/52A Frequency Counter to measure frequency
on Channel 1.
Turn on the Agilent 53147A/148A/149A's internal power reference oscillator:
Press Shift + Menu, use the up and/or down arrow keys to cycle through
the menu to PWR REF, press the right-arrow key, then use the up or down
arrow key to change the setting to ON, and press the Enter key. The
The reference oscillator is normally off. It is turned on automatically
during calibration and then turned back off when calibration is complete.
Setting PWR REF in the 53147A/148A/149A's menu to ON turns the power
reference oscillator on, and it remains on until the PWR REF menu setting
is returned to OFF. When you calibrate the Power Meter with PWR REF
set to ON, the power reference oscillator remains on after calibration is
complete.
Insert a small, non-conductive, slot-type adjustment tool into the hole
in the side of the power reference oscillator shield (see Figure 2-3).
This opening allows access to L9, the adjustable inductor that is used to
adjust the frequency of the power reference oscillator.
