SCPI Specific and Implied Channel
Some commands, such as PULSe, allow specifying a channel with an optional
numeric keyword suffix. The suffix will be shown in square brackets [ 1 / 2 ]. The
brackets are not part of command and are not to be sent to the pulse generator.
The numeric parameters correspond to the following channels: 0 = To, 1 = ChA,
2 = ChB, etc. Only one channel may be specified at a time.
If you do not specify the channel number, the implied channel is specified by the
:INSTrument:SELect command or the last referenced channel. After power-up or
reset (*RST), the instrument default is channel #1.
SCPI Parameter Types
The following parameter types are used:
<numeric value> Accepts all commonly used decimal representation of
numbers including optional signs, decimal points and
scientific notation:

<boolean value> Represents a single binary condition that is either true
or false. True is represented by a 1 or ON; false is rep-
resented by a 0 or OFF. Queries return 1 or 0.
