:BLER:SETup:DENable <DEnable>
:BERT:SETup:DENable <DEnable>
Activates/deactivates the use of the Data Enable signal and the polarity of the signal if
it is used. The Data Enable signal marks the data that is actually to be evaluated for
the BER measurement. Any data in addition to the PRBS sequence is masked and
thus not evaluated (e.g. sync, preambles, other channels, etc that are present in the
data bits supplied by the DUT).
Parameters:
<DEnable> OFF | LOW | HIGH
OFF
Any signal at the Data Enable input is ignored; all data at the
BERT data input is used for the measurement.
HIGH
The Data Enable signal is used. The only data measured is the
data at the BERT data input during a high level of the Data
Enable signal. The measurement is interrupted during a low
level of the Data Enable signal.
LOW
The Data Enable signal is used. The only data measured is the
data at the BERT data input during a low level of the Data
Enable signal. The measurement is interrupted during a high
level of the Data Enable signal.
*RST:
OFF
Example:
BERT:SET:DEN HIGH
The measurement is interrupted during the low level of the Data
Enable input.
Manual operation: See "Data Enable" on page 194
:BERT:SETup:IGNore <Ignore>
Activates/deactivates ignoring of pure "0" or "1" bit sequences at least 32 bits long.
Activating excludes faulty frames from the measurement. In the case of some mobile
radio standards, pure "0" or "1" bit sequences are generated when errors (e.g. an
incorrect checksum) are detected within a frame. These sequences, instead of the
frame data, are provided for the BER measurement and signal that the frame in ques-
tion should not be used for the measurement.
