Boolean Parameters; Ascii String Parameters; Channel List Parameters - Agilent Technologies U2300A Series Programming Manual

Boolean Parameters

Boolean parameters represent a single binary condition that is either true
or false. For a false condition, the instrument will accept "OFF" or "0".
For a true condition, the instrument will accept "ON" or "1". When you
query a Boolean setting, the instrument will always return "0" or "1".
The following command requires a Boolean parameter:
INPut:IMPedance:AUTO {OFF|0|ON|1}[,(@<ch_list>)]

ASCII String Parameters

String parameters can contain virtually any set of ASCII characters. A
string must begin and end with matching quotes; either with a single
quote or a double quote. You can include the quote delimiter as part of
the string by typing it twice without any characters in between. The
following command uses a string parameter:
DISPlay:TEXT <quoted string>
For example, the following command displays the message
"SCANNING..." on the instrument's front panel (the quotes are not
displayed).
DISPlay:TEXT "SCANNING..."
You can also display the same message using the following command with
single quotes.
DISPlay:TEXT 'SCANNING...'

Channel List Parameters

Channel list parameters have the form (@sccc), where s is the mainframe
slot number (1 through 8) and ccc is the channel number. You can specify
a single channel, multiple channels, or a range of channels. The channel
list must be preceded with the "@" symbol and must be enclosed in
parentheses. The following commands use a channel list (<ch_list>)
