Digital Average Power Troubleshooting
Digital Average Power Troubleshooting
Possible Setup Issues
IMPORTANT If the Access Probe Power measurement is currently selected and the Trigger Arm setting is
Continuous, all other measurements are disabled. Use the “SETup:CAPPower:CONTinuous”
command to set the trigger arm state to single and retry this measurement.
During remote operation of this measurement, you should configure the Trigger Arm to Single. See
“SETup:DAPower” . If single triggering is used during manual operation, press the START SINGLE key to
trigger each measurement.
The input signal must conform to “Input Signal Requirements” on page 51.
Digital average power measurement results are affected by the Amplitude Offset value. Use the
“SYSTem:CORRection:GAIN” command to determine offset values.
The test set receiver’s expected signal amplitude and channel number (or frequency) must be set up correctly
for accurate measurements. This is normally done automatically (see “Active Cell Operating Mode” ) but can
also be done manually (see “Receiver Control” on page 194) .
Interpreting Integrity Indicator values
See “Integrity Indicator” on page 222.
If over range (5) is returned the input power has exceeded the test set’s internal sampler maximum value
during some part of the sampling or the input power has exceeded the calibrated range of the test set’s power
detector.
If under range (6) is returned the measurement result is below the expected input power level. Under range is
also indicated if the input power is below the calibrated range of the test set’s power detector.
If the signal has both over range and under range conditions, only the over range (5) will be indicated.
