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.

6

Connect an Agilent E9635A adapter to the Power Meter 

OUTPUT

 connector 

as shown in Figure 2-2.

7

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.

8

Set the Agilent 53150A/51A/52A Frequency Counter to measure frequency 
on Channel 1.

9

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 

Pwr Ref

 annunciator should now be activated.

NOTE

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.

10

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.
