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 191
: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.
Parameters:
<Ignore> OFF | ZERO | ONE
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.
*RST:
OFF
Example: BERT:SET:IGN ONE
specifies that bit sequences of "1" data at least 32 bits long are
not used for the measurement.
Manual operation: See "Pattern Ignore" on page 192
