Chapter 3 Programming Your Universal Counter for Remote Operation

Elements of SCPI Commands

3-12 Programming Guide

Parameter Separator

If you send more than one parameter with a single command, you must separate

adjacent parameters with a comma.

Query Parameters

All selectable <numeric value> parameters can be queried to return the minimum

or maximum values they are capable of being set to by sending a MINimum or

MAXimum parameter after the “?.” For example, consider the INPut:IMPedance?

query.

If you send the query without specifying a parameter (INP:IMP?), the present

impedance value is returned. If you send the MIN parameter (using INP:IMP?

MIN), the command returns the minimum level currently available. If you send the

MAX parameter, the command returns the maximum level currently available. Be

sure to place a space between the question mark and the parameter.

Suffixes

A suffix is the combination of suffix elements and multipliers that can be used to

interpret the <numeric value> sent. If a suffix is not specified, the Counter

assumes that <numeric value> is unscaled (that is, Volts, seconds, etc.)

For example, the following two commands are equivalent:

OUTPUT 703;"INP:IMP 1 MOHM"

OUTPUT 703;"INP:IMP 1E+6"

Suffix Elements

Suffix elements , such as HZ (Hertz), S (seconds), V (volts),

OHM (Ohms), PCT (percent), and DEG (degrees) are allowed within this format.
