E4416A/E4417A Power Meters Service Guide 53
1 Record the input VRC magnitude of the thermistor mount at 50 MHz with
the Agilent 432A power meter set to 200 Ω:
• |R1| ___________
2 Record the input VRC magnitude of the thermistor mount at 50 MHz with
the Agilent 432A power meter set to 100 Ω:
• |R2| ___________
3 Set the Agilent 432A mount resistance switch to 200 Ω.
4 Set the DVM to measure resistance:
Connect the DVM between the VRF connector on the rear panel of
theAgilent 432A and pin 1 on the thermistor mount end of the sensor cable.
Verify that no power is applied to the Agilent 432A.
5 Round off the DVM reading to two decimal places. Record this value as the
first internal bridge resistance (R
1
) of the Agilent 432A:
• R
1
___________ Ω
6 Set the Agilent 432A mount resistance switch to 100 Ω.
7 Round off the DVM reading to two decimal places. Record this value as the
second internal bridge resistance (R
2
) of the Agilent 432A:
• R
2
___________ Ω
8 Set the Agilent 432A mount resistance switch to 200 Ω.
9 Connect the equipment as shown in Figure 2- 10 ensuring that the DVM
input leads are isolated from chassis ground.
10 Preset the instrument:
• Press
then on the power meter.
• Set the Agilent 432A RANGE switch to Coarse Zero.
Steps 1 to 7 of this procedure require pre-requisite knowledge of some Agilent 432A
and 478A parameters. Refer to Appendix A for further information.
Ensure that the Agilent 432A and the power meter under test have been switched on
for at least 30 minutes before performing the following steps.
