Mode Parameters
Loopback BER TFCI Detection Mode, TD-SCDMA
This parameter allows you to specify the detection state of TFCI used in TD-SCDMA Loopback BER
calculation,Auto or Manual. Its type is bool. True means auto detection mode.

Loopback BER TFCI Word, TD-SCDMA
This parameter allows you to specify the TFCI word used in TD-SCDMA Loopback BER calculation.
Its type is int.
:SERVice[:PRODuction]:LSEQuencer:ADVanced:TDSCdma:LBER:TFCI <int>
:SERVice[:PRODuction]:LSEQuencer:ADVanced:TDSCdma:LBER:TFCI?
PVT Demodulation State
The parameter specifies if demodulation is needed for TDSCDMA PVT measurement. If this parameter
is ON, the midamble of the analysis time slot will be searched and the burst start and stop time will be
calculated accordingly; if this parameter is OFF, the burst start and stop timing are calculated by the burst
powers. No demodulation is performed.

PVT Momentum Criterion
This parameter specifies Momentum Criterion will be used for limit check.
If this parameter is ON, Momentum TDSCDMA PVT limit check criterion will be used. That is, Off
Power Before, Average Power over -33rd ~ -14th chip and Off Power After results (see TDSCDMA
PVT Results) will be used to compare upper limit -65 dBm, -50 dBm and -65 dBm respectively. If all of
these 3 power values are below their upper limits, the TDSCDMA PVT Overall Pass/Fail result will be
passed; otherwise, the Overall Pass/Fail result will be failed.
If this parameter is OFF, the TDSCDMA PVT envelope trace will be used to compare with the upper
limit trace point by point. If any point of the envelope power trace is less than the upper limit trace, the
TDSCDMA PVT Overall Pass/Fail result will be passed; otherwise, the Overall Pass/Fail result will be
failed. For the details of envelop trace result and upper limit trace result, please refer to Envelope Trace
Results and Upper Limit Results.
