33 Trigger Commands
Advanced Comm Trigger Commands
Use the COMM Trigger Mode to find a serial pattern of bits in a waveform.
The COMM Trigger Mode is primarily used to find an isolated logically one
bit in a waveform for mask testing applications. The pattern is defined by
the standards used by the telecommunication and data communication
industries. Mask testing is used to verify a waveform meets industrial
standards which guarantees that equipment made by different
manufacturers will work together.

Before Executing
Commands
Before you can execute the :TRIGger:ADVanced:COMMunications
commands, mask testing must be enabled at least one time. The
:MTESt:ENABle command enables or disables mask testing. Then you can
set the mode by entering:
:TRIGger:MODE ADVanced and
:TRIGger:ADVanced:MODE COMM
To query the oscilloscope for the advanced trigger mode, enter:
:TRIGger:ADVanced:MODE?
The :TRIGger:ADVanced:COMM commands define the Communications
Trigger Mode. As described in the following commands, you set up the
:TRIGger:ADVanced:COMM commands with the following commands and
queries.
