R&S AFQ100A
BERT:STOP
Stops an ongoing measurement.
This command triggers an event and hence has no query and no *RST value.
Example: BERT:STOP
*RST value Resolution Options
- -
BERT:UNIT ENGineering | SCIentific | PCT | PPM
Sets the unit for the error rate display on the screen. BERT:RES? always specifies the error rate as
the quotient of "Number of errors" and "Number of data items", unaffected by this command.

Parameters:
SCIentific

[SOURce:]INPut:BERT:IMPedance G50 | G1K
The command sets the impedance of the BERT inputs Clock, Data, Data Enable and Restart.
Example: INP:BERT:IMP G50

'stops the measurement. To start a new measurement, the BER measurement
must be switched on again by BERT:STAT ON.
Dependencies
These commands automatically set BERT:STATe to OFF
The error rate is output in exponential notation with the exponent –3 or –6.
The error rate is output in scientific notation, i.e. standardized to one place to
the left of the decimal.
The error rate is output in percent.
The error rate is output in parts per million.
'selects the unit "ppm" for the display of the error rate.
Resolution Options
'the impedance of the BERT inputs is set to 50 ohm to ground.
