12 :COMPliance Commands
:COMPliance:USB:SOURce:DPLus
(see page 1610)
Command Syntax
:COMPliance:USB:SOURce:DPLus <source>
<source> ::= {CHANnel<n>}
<n> ::= 1 to (# analog channels) in NR1 format
The :COMPliance:USB:SOURce:DPLus command specifies the analog input
channel that is probing the D+ signal.
On 4-channel oscilloscopes, you are forced to use different channel pairs for the
D+ and D- signals. This provides the maximum sample rate. (Channels 1 and 2 are
one pair and channels 3 and 4 are the other pair.)
Query Syntax

The :COMPliance:USB:SOURce:DPLus? query returns the specified analog input
channel.
Return Format
