Parameters:
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.
OFF
<Denable>
*RST:
BERT:SET:DEN HIGH
The measurement is interrupted during the low level of the Data
Enable input.
Example:
:BERT:SETup:IGNore <Ignore>
Activates/deactivates ignoring of pure "0" or "1" bit sequences at least 32 bits long. Acti-
vating 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 question should not be
used for the measurement.
Parameters:
OFF|ONE|ZERO
OFF
Pattern Ignore is not active.
ONE
Bit sequences consisting of 32 or more consecutive "1" data are
not used (i.e. ignored) for the BER mesaurement.
ZERO
Bit sequence consisting of 32 or more consecutive "0" data are not
used (i.e. ignored) for the BER measurement.
OFF
<Ignore>
*RST:
BERT:SET:IGN ONE
specifies that bit sequences of "1" data at least 32 bits long are not
used for the measurement.
