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:CFERror:CONTinuous . If single triggering is used during manual operation, press the START SINGLE key to trigger each measurement.
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 ).
A call must be connected with a loopback service option selected (see CALL:SOPTion ) to perform frame error rate measurements.
Frame error rate measurements require an accurate Amplitude Offset value because of the low levels transmitted during sensitivity measurements. Use the SYSTem:CORRection:GAIN command to set offset values.
When the frame error rate measurement is running, changing
PLCM Type
causes this measurement aborted and restarted. See
PLCM Type
for details.
For the
lab application
, when the
F-FCH/Traffic Frame Pattern State
is set to On and the
F-FCH/Traffic Frame Pattern Good Frames
is set to a value less than three the FER measurement may not be able to synchronize with the mobile station. An error message will be generated if the
F-FCH/Traffic Frame Pattern State
is set to On, the
F-FCH/Traffic Pattern Good Frames
is set to a value less than three, and the FER measurement is running. See
