:MEASure:GSM:ARRay:RFRX:BER:ALL
Syntax
:MEASure:GSM:ARRay:RFRX:BER:ALL <int1>
Parameters
int1 is an integer.
The minimum value for int1 is 0, the maximum value is 100. The default value for int1 is 0.
Description
Performs a sequential measurement of the (nonresidual) residual bit error ratios (RBER) a specific number of times
(set with the int1 parameter). To read out the entire measurement results array, use the :FETCh:GSM:RFRX:BER:ALL
command.
The RF RX tests performed by this command are:
CIA, the (nonresidual) bit error ratio of the class Ia bits,
CIB, the (nonresidual) bit error ratio of the class Ib bits, and
CII, the (nonresidual) 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.
- More information regarding ARRay measurements can be found in section MEASure:ARRay.
Query
The query form of this command performs the measurements the specified number of times (int1 parameter). After
all measurements have been completed and all measurement results obtained, the query delivers a string, containing
(3 * int1) measurement result values. The single measurement result values are separated by commas. All
measurement result values are floating point real numbers. The order of the measurement result values delivered
back is as follows:
1. CIA, representing the (nonresidual) bit error ratio of the class Ia bits,
2. CIB, representing the (nonresidual) bit error ratio of the class Ib bits, and
3. CII, representing the (nonresidual) bit error ratio of the class II bits.
Example
:MEASure:GSM:ARRay:RFRX:BER:ALL 2
:FETCh:GSM:RFRX:BER:ALL?
In this case, the sequence of the (nonresidual) bit error measurements is performed twice. All six measurement result
values are kept in an internal memory until they are read out with the FETCh command.
The string returned is:
"0.1,1.5,0.0,0.2,2.7,0.1".
