6-8 GPIB Operation

• <NRf> Numeric representation format — This parameter is a number that can be

expressed as an integer (e.g., 8), a real number (e.g., 23.6), or an exponent

(2.3E6). Example:

SENSe:AVERage 5 Set average count value to 5

• <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 parameter is used, the instru-

ment is programmed to the largest allowable value. Examples:

:SENSe:NPLCycles 2 Set integration period to 2 PLC

:SENSe:NPLCycles DEFault Set integration period to 1 PLC

:SENSe:NPLCycles MINimum Set integration period to 0.01 PLC

:SENSe:NPLCycles MAXimum Set integration period to 10 PLC

• <numlist> Numlist — Specify one or more numbers for a list. Example:

:STATus:QUEue:ENABle (-110:-222) Enable errors -110 thru -222

Angle Brackets < > — Angle brackets (< >) are used to denote a parameter type. Do not in-

clude the brackets in the program message. For example:

:OUTPut <b>

The <b> indicates that a Boolean-type parameter is required. Therefore, to turn on the output,

the command with the ON or 1 parameter must be sent as follows.

:OUTPut ON

:OUTPut 1

Query commands

This type of command requests (queries) 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. Example:

:SENSe:CURRent:RANGe? Queries the present current range.

Most commands that require a numeric parameter (<n>) can also use the DEFault, MINi-

mum, 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. Examples:

:SENSe:CURRent:RANGe? DEFault Queries the *RST default value.

:SENSe:CURRent:RANGe? MINimum Queries the lowest allowable value.

:SENSe:CURRent:RANGe? MAXimum Queries the largest allowable value.
