R&S AFQ100A
BERT:SETup:IGNore OFF | ONE | ZERO
Activates/deactivates ignoring of pure "0" or "1" bit sequences at least 32 bits long. The activating of
Pattern Ignore 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 signalize that the frame in question should not be used for the measurement.
OFF
Parameters:
ONE (All 1)
ZERO (All 0)
Example: BERT:SET:IGN ONE
*RST value
OFF
BERT:SETup:MCOunt 0.0 ... 2^32-1
Enters the number of transmitted data bits/data blocks to be checked before the measurement is
terminated. With a BER measurement, data that was suppressed by BERT:SETup:DENable is not
counted. This termination criterion always terminates the measurement after the specified number of
data bits/data blocks. Starting from this point, the fourth value is output with 1 (= terminate
measurement) if the result is queried with :BERT:RES?. If the continuous measurement mode
(BERT:SEQ AUTO) has been selected, the measurement is restarted once the results have been
queried.
Example: BERT:SET:MCO 1E6
*RST value

Pattern Ignore is not active.
Bit sequences consisting of 32 or more consecutive "1" data are not used (i.e.
ignored) for the BER measurement.
Bit sequences consisting of 32 or more consecutive "0" data are not used (i.e.
ignored) for the BER measurement.
'specifies that bit sequences of "1" data at least 32 bits long are not used for
the measurement.
Resolution Options
'sets a measurement over 1000000 data bits.
