Programming Reference

Gating Time

:SENS1:GATE:PER

Syntax :SENS1:GATE:PER? :SENS1:GATE:PER integer

Description Either gets or sets the duration of the gating interval. The allowed range for the gating time is 1s to 608399s (168 hours, 59 minutes, 59 seconds). The gating time is always in seconds. Fractional seconds are not supported, and will be rounded to the closest time in seconds.

Gating Bit Error Rate

:SENS1:FETC:ERAT

Syntax :SENS1:FETC:ERAT?

Description Gets the bit error ration that is captured during the gating interval. This value might/will change while the gating is in progress, and will freeze at the end of the gating interval.

Gating Number of Errors

:SENS1:FETC:ECO

Syntax :SENS1:FETC:ECO?

Description Gets the number of errors that have been counted during the gating interval. This value might/will change while gating is in progress, and will freeze at the end of the gating interval.

Start Gating

:SENS1:GATE:STAT 1

Syntax :SENS1:GATE:STAT 1ON

Description Starts a new gating period. This command will be ignored if a gating period is already in progress.

Abort Gating

:SENS1:GATE:STAT 0

Syntax :SENS1:GATE:STAT 0OFF

Description This command aborts the currently active gating period immediately. It will be ignored if the gating is not in progress.
