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.
