:SOURce:DIFFerential

Command Syntax

:SOURceN:DIFFerential  {ON | OFF | 1 | 0}

Where N identifies a simulated module's specific channel and must be selected from {1:8}{A|B|C|D}. For example, SOURce3C.

Query Syntax

:SOURceN:DIFFerential?

Query Response

{1 | 0}

Description

Turns on differential tracking between the two channels of a simulated electrical module. The two channels are the primary (+) channel waveform (for example, 6A) and the secondary (−) channel waveform (in this example, 6B). When differential tracking is turned on, the channel primary (+) channel waveform settings (data type, amplitude, and offset) are copied into the secondary (−) channel setup. The polarity of the amplitude and offset values are reversed. For secondary channels, this command can only be queried. While differential tracking is on, the settings for a secondary (−) channel can not be changed. For example, the amplitude of the channel can not be changed. This command does not work on simulated optical channels.
