Table F-23: Test Cable Set–up (using the HP PCS Interface) Calibration Procedure
n ActionStep
15 HP83226A: Perform the following actions.
15a Position the cursor on Show Frequency and Level Details and select it.
15b Under HP83236 Frequencies and Levels, record the Generator Level.
15c Position the cursor on Prev Menu and select it.
15d Proceed to Step 17.
16 HP83226B: Perform the following actions.
16a Position the cursor on Show Frequency and Level Details and select it.
16b Under HP83236B Frequencies and Levels, record the Generator Frequency Level (1850 –
1910 MHz).
16c Position the cursor on Prev Menu and select it.
17 Click on Pause for Manual Measurement.
18 Connect the Power Sensor directly to the RF OUT ONLY Port of the PCS Interface.
19 On the HP 8921A, under To Screen, select CDMA GEN.
20 Move the cursor to the Amplitude field and click on the Amplitude Value.
21 Increase the Amplitude Value until the Power Meter reads 0 dBm ±0.2 dB.
NOTE
The Amplitude Value can be increased coarsely until 0 dBM is reached; then fine tune the
Amplitude by adjusting the Increment Set to 0.1 dBm and targeting in on 0 dBm.
22 Disconnect the Power Sensor from the RF OUT ONLY port of the PCS Interface.
NOTE
The Power Meter Sensor’s lower limit is –30dBm. Thus, only components having losses ≤30 dB
should be measured using this method.
For further accuracy, always re-zero the Power Meter before connecting the Power Sensor to
the component being calibrated.
– After connecting the Power Sensor to the component, record the calibrated Loss
immediately.
23 Disconnect all components in the Test Set–up in order to calibrate each component separately.
23a Connect each component, one-at-a-time, between the RF OUT ONLY PORT and the Power Sensor.
23b Record the calibrated Loss Value displayed on the Power Meter.
S Example: (A) Test Cable(s) = –1.4 dB
(B) 20dB Attenuator = –20.1 dB
(B) Directional Coupler = –29.8 dB
24 After all components have been calibrated, re–assemble all of the components back together.
