:SOURce:PATTern

Simulated and AWG Commands

Command Syntax

:SOURceN:PATTern <pattern>

<pattern> is a token selected from those listed below.

Where N identifies a simulated instrument's specific channel in the form "<connection1-8>_<ch1-8>" (for example, SOURce4_2). With connection 1, the connection number part (that is, "1_") is optional, and you can simply use the channel number "<ch1-8>" (for example, SOURce3 which is the same as SOURce1_3).

Query Syntax

:SOURceN:PATTern?

Description

On simulated instruments, this command selects the pattern for the source waveform.

The NRZ, PAM3, PAM4, or PAM6 format is selected using the :SOURce:FORMat command.

The DATA waveform type is selected using the :SOURce:WTYPe command.

The following patterns are available using these Tokens:
