Tx Spurious Emissions Measurement Troubleshooting
Last updated: October 28, 2004
If the access probe power measurement is on and waiting to measure a probe, all other measurements (except digital average power) will not be able to execute. It is therefore recommended that you turn off the access probe power measurement before attempting any other measurements.
For the lab application, the Tx Spurious Emissions measurement can not be initiated when the MS is in gated transmission on the R-FCH (see
R-FCH Gating
for details).
Possible Setup Issues
-
To obtain valid measurement results, the Tx Spurious Emissions measurement requires the MS is in a loopback call connection at full data rate transmission (see also
Testing 4.5.1 Conducted Spurious Emissions
). The measurement still returns results which appear to be valid even when the MS is in gated transmission. You should make sure that the mobile station is configured properly to obtain the desired result.
-
During remote operation of this measurement, you should configure the Trigger Arm to Single. See
SETup:CTXSpurious:CONTinuous
. If single triggering is used during manual operation, press the
START SINGLE
key to trigger each measurement.
Troubleshooting Techniques
-
Check to see if an integrity indicator other than 0 (normal) was returned with a measurement result (see
Integrity Indicator
).
