Measurement Procedure
On the Measuring Receiver:
1. Press the PRESET key on the Test Set.
2. After replacing the coupler with the Test Set, make a TUNED RF LEVEL measure-
ment, in mW, with the measuring receiver. Record the measured level as Tune RF #2
in step 11.
3. On the Test Set push PRESET.
4. Access the CONFIGURE screen.
5. Set
(Gen) - (Anl)
to 0 MHz.
6. Set the
RF Display
field to
Freq
.
7. Access the CDMA CALL CTRL screen.
8. Change the Avg Power measurement units to
mW
.
9. Set the
RF Gen Freq
field to
840 MHz
.
10. Zero the power meter: a: Temporarily disconnect all RF inputs to the HP 8924E.
a. Select Zero (under the
Power Meas
label).
b. Set
Sector PWR to off.
11. Reconnect the output of the directional coupler to the 8924E’s Test Set RF IN/OUT
connector (connect directly - no cables).
12. Read the
Avg Power
field in mW, and record it as UUT Power in step 11.
13. Calculate the Measured Power as follows:
14. Repeat the Calibration and Measurement procedures for each of the frequencies listed
in the PTR.
