HP8935 Power Delta Calibration
Follow the procedure in Table I-3 to perform the HP8935 Power Delta
Calibration procedure.
Table I-3: HP8935 Power Delta Calibration Procedure
Step Action
NOTE
Perform this procedure after test equipment has been allowed to warm-up and stabilize for a minimum
of 60 minutes.
1 Connect a short RF cable between the HP8935 Duplex Out port and the HP437B power sensor (see
Figure I-5).
2 Set the HP8935 signal source as follows:
- Measure mode to CDMA Gen
- Frequency to the CDMA Calibration target frequency
- CW RF Path to IQ
- Output Port to Dupl
- Data Source to Random
- Amplitude to 0 dBm
3 Measure and record the power value reading on the HP437B Power Meter.
4 Record the Power Meter reading as result A ________________________.
5 Turn off the source HP8935 signal output, and disconnect the HP437B.
NOTE
Leave the settings on the source HP8935 for convenience in the following steps.
6 Connect the short RF cable between the source HP8935 Duplex Out port and the RF-IN/OUT port
(see Figure I-6).
7 Ensure that the source HP8935 settings are the same as in Step 2.
8 Set the measuring HP8935 as follows:
- Measure mode to CDMA Anl
- Frequency to the CDMA calibration target frequency
- Input Attenuation to 0 dB
- Input port to RF-IN
- Gain to Auto
- Anl Dir to Fwd
9 Turn on the source HP8935 signal output.
10 Set the Chn Pwr Cal to Calibrate and select to calibrate.
11 Measure and record the channel power reading on the measuring HP8935 as result
B ________________________.
12 Turn off the source HP8935 signal output and disconnect the equipment.
