Query commands
The query command requests the presently programmed status. It is identified by the question
mark (?) at the end of the fundamental form of the command. Most commands have a query
form.
:ARM:TIMer?
Most commands that require a numeric parameter (<n>) can also use the DEFault,
MINimum, and MAXimum parameters for the query form. These query forms are used to
determine the *RST default value and the upper and lower limits for the fundamental command.
:ARM:TIMer? DEFault
:ARM:TIMer? MINimum
:ARM:TIMer? MAXimum
<NDN> Non-decimal numeric — A non-decimal value that can be used to
program status enable registers. A unique header identifies the format;
#B (binary), #H (hexadecimal) and #Q (octal). See "Programming
Enable Registers" in Section 13 for details.
*SRE #B10001
<n> Numeric value — Can consist of an NRf number or one of the following
name parameters: DEFault, MINimum, or MAXimum. When the
DEFault parameter is used, the instrument is programmed to the *RST
default value. When the MINimum parameter is used, the instrument is
programmed to the lowest allowable value. When the MAXimum
parameter is used, the instrument is programmed to the largest allowable
value.
:ARM:TIMer 0.1
:ARM:TIMer DEFault
:ARM:TIMer MINimum
:ARM:TIMer MAXimum
Angle brackets < > — Used to denote a parameter type. Do not include the brackets in
the program message.
:DISPlay:ENABle <b>
The <b> indicates that a Boolean type parameter is required. Thus, to enable the display,
you must send the command with the ON or 1 parameter as follows.
:DISPlay:ENABle ON or 1
