:TRIGger:MODe

Command Syntax

:TRIGger:MODe {FILTered | EDGE | CLOCk}

Query Syntax

:TRIGger:MODe?

Description

When the trigger source is set to the front panel (:TRIGger:SOURce FPANel) and pattern lock is turned off (:TRIGger:PLOCk OFF), selects the trigger mode in Oscilloscope mode and Eye/Mask mode:

FILTered

Selects Filtered Edge (DC to 100 MHz) trigger bandwidth. You can set the trigger level using the :TRIGger:LEVel command.

EDGE

Selects Standard Edge (DC to 3.2 GHz) trigger bandwidth.

CLOCk

Selects Clock/Divided (3 GHz to 13 GHz) trigger bandwidth.

The trigger signal's sensitivity to noise and response time is affected by the bandwidth. Selection of the proper mode (bandwidth) is a compromise between the trigger's response to very fast edge speeds and its sensitivity to noise. Noise on the trigger signal can result in inconsistent triggering, which is seen as timing instability (jitter) in the displayed waveform. To reduce the occurrence of inconsistent triggering, reduce the bandwidth of the trigger circuitry. When pattern lock is turned on, triggering information is automatically detected as the FlexDCA generates a pattern lock. In this case, trigger bandwidth settings are not used and are unavailable.
