• Parameter types: The following are some of the more common parameter types:
<b> Boolean: Used to enable or disable an instrument operation. 0 or OFF dis-
ables the operation, and 1 or ON enables the operation. Example:
:CURRent:AC:RANGe:AUTO ON
<name> Name parameter: Select a parameter name from a listed group. Example:
<name> = NEVer
= NEXt
:TRACe:FEED:CONTrol NEXt
<NRf> Numeric representation format: This parameter is a number that can be ex-
pressed as an integer (e.g., 8) a real number (e.g., 23.6) or an exponent
(2.3E6). Example:
:SYSTem:KEY 16
<n> Numeric value: A numeric value parameter can consist of an NRf number or
one of the following name parameters: DEFault, MINimum, 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 param-
eter is used, the instrument is programmed to the largest allowable value. Ex-
amples:
:TRIGger:TIMer
:TRIGger:TIMer
:TRIGger:TIMer
:TRIGger:TIMer
<list> List: Specify one or more switching channels. Examples:
:ROUTe:SCAN (@1:10)
:ROUTe:SCAN (@2,4,6)
• Angle Brackets < >: Angle brackets (< >) are used to denote a parameter type. Do not
include the brackets in the program message. For example:
:HOLD:STATe <b>
The <b> indicates that a Boolean-type parameter is required. Thus, to enable the Hold
feature, you must send the command with the ON or 1 parameter as follows.
:HOLD:STATe ON or 1
