to zero the measurement channel. Channel dependent commands end with a number to indicate the desired channel as
follows:
Examples:
:CALCulate:STATe ON Turn on measurement channel 1 (default channel number)
:CALCulate1:STATe ON Turn on measurement channel 1 (specified channel number)
:CALC:STAT ON Turn on measurement channel 1 (short form, default chan #)
:CALC1:STAT ON Turn on measurement channel 1 (short form, specified chan #)
:CALCulate:STATe? Query the state of measurement channel 1 (default chan #)
:CALC:STAT? Query the state of channel 1 (short form, default chan #)
:CALCulate1:STATe? Query the state of measurement channel 1 (specified chan #)
:CALC1:STAT? Query the state of channel 1 (short form, specified chan #)
:SENSe:FILTer:TIMe 5.0 Set channel 1 averaging time to 5 seconds.
In the discussion and tables below, the following notation will be used:
Command name long and short form: SYSTem
Optional command name in brackets: SYSTem:ERRor[:NEXT]?
Command with channel dependence: CALCulate[1|2]:STATe OFF
Default channel 1: CALibration:ZERO
Explicit channel 1: CALibration1:ZERO
Select channel 2: CALibration2:ZERO
Short Form: CAL2:ZERO
Command which takes numeric argument: SENSe1:AVERage
Same command; query: SENSe1:AVERage?
Command with literal text argument: CALCulate1:UNITs
Command with no query form: *CLS
Command with query form only: FETCh1:CW:VOLTage?
SYNTAX NOTES
Square brackets [ ] are used to enclose the list of valid channels for a command, or a list of command options separated by
the vertical separator bar | character. This character is for syntax only, and is not to be entered as part of the command. By
default, if no channel number is specified, Channel 1 is selected.
A literal argument denoted by indicates a word or series of characters, which must exactly match one of
the choices for the command. An argument denoted by requires a string which, when converted to a
number, is within the range of valid arguments. Numerical values can generally be in any common form including decimal
and scientific notation. indicates an argument which must be either true or false. Boolean arguments are
represented by the values 0 or OFF for false, and 1 or ON for true. Queries of Boolean parameters always return 0 or 1.
Curly braces { } are used to enclose two or more possible choices for a mandatory entry, separated by the comma character.
One of the enclosed options MUST be inserted into the command, and the braces are not to be entered as part of the
command.
