:MEASure:GPRS[:CONTinuous]:RFRX:RBER:ALL

Syntax

:MEASure:GPRS[:CONTinuous]:RFRX:RBER:ALL

Parameters

There are no parameters.

Description

Starts a continuous measurement of the residual bit error ratios (RBER). To read out the latest measurement results,

use the :FETCh:GPRS:RFRX:RBER:ALL command.

The RF RX tests performed by this command are:

CIB, the residual bit error ratio of the class Ib bits,

CII, the residual bit error ratio of the class II bits, and

FER, the frame erasure ratio.

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:GPRS: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. CIB, representing the residual bit error ratio of the class Ib bits,

2. CII, representing the residual bit error ratio of the class II bits and

3. FER, representing the frame erasure ratio.

The single result values are separated by commas.

Example

:MEAS:GPRS:CONT:RFRX:RBER:ALL?

In this case, all RBER measurements are performed. As soon as all measurements have been completed and all

measurement results obtained, a string is delivered back containing the three measurement result values:
