:MEASure:GSM[:CONTinuous]:RFRX:BER:ALL
Syntax
:MEASure:GSM[:CONTinuous]:RFRX:BER:ALL
Parameters
There are no parameters.
Description
Starts a continuous measurement of the (nonresidual) bit error ratios (BER). To read out the latest measurement
results, use the :FETCh:GSM:RFRX:BER:ALL command.
The RF RX tests performed on this command are:
CIA, the bit error ratio of the class Ia bits,
CIB, the bit error ratio of the class Ib bits, and
CII, the bit error ratio of the class II bits.
Notes:- Please keep in mind that the start of a new RF RX test always terminates the preceding one instantly.
- The number of samples to be used for testing can be set, using the :CONF:GSM:BER:COUNt command.
Query
The query form of this command starts the measurements and - after all measurements have been completed and
all measurement results obtained - delivers a string, containing three floating point real numbers. The order and
meaning of these numbers delivered back is as follows:
1. CIA, representing the bit error ratio of the class Ia bits,
2. CIB, representing the bit error ratio of the class Ib bits, and
3. CII, representing the bit error ratio of the class II bits.
The single measurement result values are separated by commas.
Example
:MEASure:GSM:CONTinuous:RFRX:BER:ALL?
In this case, all BER measurements are performed in a sequence. As soon as all measurements have been completed
and all measurement results obtained, a string is delivered back containing the three measurement result values:
"0.0,0.0,0.2".
