Keithley 2302 User Manual

7-10 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[1]:AVERage 5Set average count value to 5 for battery channel (#1)
• <n> Numeric value — A numeric value parameter c
an 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
instrument is programmed to the largest allowable value. Examples:
:SENSe[1]:NPLCycles 2 Set integration period to 2 PLC
:SENSe[1]:NPLCycles DEFault Set integration period to 1 PLC
:SENSe[1]:NPLCycles MINimum Set integration period to 0.01 PLC
:SENSe[1]: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 < > — An
gle brackets (< >) are used to denote a parameter type. Do not
include the brackets in the program message. For example:
:OUTPut[1] <b>
The <b> indicates that a Boolean-type parameter is required. Therefore, to turn on the output
for
the battery channel (#1), the command with the ON or 1 parameter must be sent as follows.
:OUTPut[1] ON
:OUTPut[1] 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[1]:CURRent:RANGe? Queries the present current range for
the battery channe
l (#1).
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.
Examples:
:SENSe[1]:CURRent:RANGe? DEFault Queries th
e *RST default value.
:SENSe[1]:CURRent:RANGe? MINimum Queries the lowest allowable value.
:SENSe[1]:CURRent:RANGe? MAXimum Queries the largest allowable value.
