Performance Verification 2-15 Power Meter Verification (Option 29)
S312D MM PN: 10580-00195 Revision B 2-29
Procedure:
1. Turn on the power meter and signal source.
2. On the power meter, press the
Channel
key, the
Setup
soft key and then the
CHANNEL
soft key to display
Channel 2 setup menu. Press the
INPUT
key twice to set the input configuration to B. Press the
Sensor
key
to display both Sensor A and Sensor B Readings.
3. Connect the power sensors to the power meter and calibrate the sensors.
4. Set the Synthesized Signal Generator output power level to 5 dBm.
5. Set the Synthesized Signal Generator output to 50 MHz CW.
6. On the power meter, press the
Sensor
key, the
Cal Factor
soft key, and then the
FREQ
soft key. Use the
keypad to enter
50 MHz
as the input signal frequency, which sets the power meter to the proper power
sensor calibration factor. Repeat for Sensor B. Press the
System
key on the power meter to display the
power reading.
7. Connect Sensor A to the Synthesized Signal Generator output, measure the output power level, and
record the value in column A of
Table A-17, “Power Meter Verification (Option 29) Output Power Level”
on page A-9 .
8. Disconnect Sensor A from the Synthesized Signal Generator output.
9. Connect the power splitter to the Synthesized Signal Generator output and connect Sensor B to one of the
power splitter output connections. Install the 10 dB Fixed Attenuator to the other power splitter output
connection, and then connect Sensor A to the end of the Attenuator. Refer to
Figure 2-13 .
10. Record the new Sensor A reading in column B of Table A-17 .
11. Record the Sensor B reading in column D of Table A-17 .
12. Calculate the Splitter/Attenuator Combined Loss by using the following formula and record the result in
column C of
Table A-17 :
C = A – B
13. Calculate the Sensor B Path Power Splitter Loss by using the following formula and record the result in
column E of
Table A-17 :
E = A – D
14. Display Sensor A on the power meter.
15. Repeat Step 5 through Step 14 for 1000 MHz and 1580 MHz.
16. Calculate the desired Sensor B Readings for –30 dBm Test Power Level at the end of the 10 dB
attenuator by using the following formula:
Desired Sensor B Reading = Test Power Level + C – E
17. Record the three calculated results in Table A-18, “Power Meter Verification (Option 29) –30 dBm Test
Power Level” on page A-9 .
18. Using the power splitter, coaxial cable and adapters, connect the Site Master to the signal source and the
power sensor as shown in Figure 2-14 .
