:SOURce:DIFFerential

Command Syntax

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

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:DIFFerential?

Query Response

{1 | 0}

Description

Turns on differential tracking between the two channels of a simulated electrical instrument. 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 cannot be changed. For example, the amplitude of the channel cannot be changed. This command does not work on simulated optical channels.
