Programming a Channel Power Measurement
This section provides an example of how to make channel power measurements via GPIB. The following
program example assumes that the mobile station's (UE's) antenna output is connected to the RF IN/OUT
connector, and that the mobile station is transmitting an uplink signal.
The basic procedure to test channel power is as follows:
1. Set the channel power Setup parameters as desired using the SETup:WCPower commands.
2. Use the INITiate:WCPower command to start the measurement.
3. Use the FETCh:WCPower? query to obtain the measurement results.
Programming Example
10
OUTPUT 714;"SETup:WCPower:CONTinuous OFF"!Set the channel power
20
30
OUTPUT 714;"SETup:WCPower:TIMeout 1S"!Set a timeout value of 1 second
40
50
OUTPUT 714;"SETup:WCPower:COUNt 5"!Set multi-measurements to 5 and
60
70
OUTPUT 714;"SETup:WCPower:INTerval:TIME 666.7US"!Set the measurement interval
80
90
OUTPUT 714;"SETup:WCPower:TRIGger:SOURce AUTO" !Set the trigger source
100
110
OUTPUT 714;"INITiate:WCPower"!Start the channel power measurement.
120
OUTPUT 714;"FETCh:WCPower?"!Query the returned integrity indicator and the
130
140
ENTER 714;Integrity,Wcpower!Enter the returned values into variables.
150
IF Integrity<>0 THEN !Integrity <> 0 indicates an invalid measurement.
170
PRINT "Measurement problem; check for signal level over/under range condition."
171
ELSE
180
END IF
190
END
Returned Values
• Integrity stores the returned integrity indicator value (see
measurement with no errors.
• Wcpower returns the average channel power measurement value in dBm.
!measurement to single trigger mode.
!in case the measurement cannot be made.
!enable multi-measurements.
!average channel power measurement.
