544 Operating Manual 1176.8016.02 ─ 17
Example: INP:BERT:IMP G50
The impedance of the BERT inputs is set to 50 ohm to ground.
Manual operation: See "Impedance" on page 195
[:SOURce]:INPut:BERT:THReshold <Threshold>
Sets the high/low threshold of the BERT inputs Clock, Data, Data Enable and
Restart . In the case of positive polarity, this threshold determines the point as of which
a signal is high (active) or low (inactive).
Parameters:
<Threshold> float
Range:
0.01 to 2
Increment: 0.01
*RST:
1
Default unit: Volt
Example: INP:BERT:THR 1 V
A high/low threshold of 1 volt is set at the BERT inputs. The sig-
nal is high (active) for a signal voltage of 1 volt and higher.
Manual operation: See "Threshold" on page 195
:TRIGger:BLER[:IMMediate]
:TRIGger:BERT[:IMMediate]
Triggers a single bit error rate or block error rate measurement if the single trigger
mode (
BERT|BLER:SEQ SING
) is selected.
Example: BERT:SEQ SING
selects the single trigger mode.
Example: TRIG:BERT
starts a single bit error rate measurement.
Usage: Event
7.6 CALibration Subsystem
The
CALibration
system contains the commands for performing internal adjustment.
Adjustment is triggered by the query commands.
Understanding the query reponse
●
0
: error-free execution of teh adjustements
●
1
: indicates that an error ocurred, the process has been canceled.
