:BLER:SEQuence <Sequence>
:BERT:SEQuence <Sequence>
Selects the type of measurement: single or continuous measurement.
These commands are automatically set to AUTO by
BERT:STARt
or
BLER:STARt
.
Parameters:
<Sequence> AUTO | SINGle
AUTO
Continuous measurement. If one or both termination criteria are
met, the measurement in progress is terminated. At the end of a
measurement, the restart of a new one is delayed until the first
measurement result has been queried with
BERT:RES
. The
resulting brief measurement interruption is irrelevant because
the subsequent measurement will be synchronized within 24
data bits.
SIINGle
Single measurement. A single measurement must be started
with
:TRIG:BERT
. A single measurement is terminated once
the set number of data bits/blocks or number of errors is
reached
*RST:
AUTO
Example: BERT:SEQ SING
selects single measurement.
Example: TRIG: BERT
starts the single measurement.
Options: Dependencies: These commands are automatically set to AUTO
by BERT:STARt or BLER:STARt
Manual operation: See "Mode" on page 189
:BLER:SETup:CLOCk[:POLarity] <Polarity>
:BERT:SETup:CLOCk[:POLarity] <Polarity>
Sets the polarity of the active slope of the feedback clock.
Parameters:
<Polarity> RISing | FALLing
RISing
The positive slope of the clock signal is active.
FALLing
The negative slope of the clock signal is active.
*RST:
RISing
Example: BERT:SET:CLOC FALL
selects the falling slope of the clock signal as the active slope.
Manual operation: See "Clock Slope" on page 190
