Example
OUTPUT 725; ":SENS:SWE:TIME 10"
OUTPUT 725; ":TRIG:INIT"
WAIT 2
OUTPUT 725; ":TRIG:SAMPLE”
OUTPUT 725; ":SENS:DATA? BER”
ENTER 725; value$
PRINT value$ ! BER value after 2 seconds
Command
:FETCh:BER? [BCOunt | ECOunt | ETIMe | BER | ALL]
Type Querry
Description Returns the selected parameter from the memory stored on the FPGA, or
returns all parameters as a vector if ALL or no parameter is specified. Does
not require the measurement to currently be running. This command can
only be used if the set-up measurement time from the command
“:SENSe:SWEep:TIME value” is completed. See examples 470-580.
BCOunt
Total number of bits counted
ECOunt Total number of errors counted
ETIMe Elapsed time (seconds)
BER Calculated Bit Error Rate, or NAN if measurement not ready
The vector is as follows: BCOunt,ECOunt,ETIMe,BER
Parameters [BCOunt | ECOunt | ETIMe | BER | ALL]
Result Described above
Example
OUTPUT 725; ":SENS:SWE:TIME 10"
OUTPUT 725; ":TRIG:INIT"
WAIT 2
OUTPUT 725; ":TRIG:SAMPLE”
OUTPUT 725; ":SENS:DATA? BER”
ENTER 725; value$
PRINT value$ ! BER value after 2 seconds
WAIT 3
OUTPUT 725; ":TRIG:ABOR"
OUTPUT 725; ":FETC:BER?"
ENTER 725; result$
PRINT result$ ! BER value after 5 seconds
