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 :GPS:REF:ADEL? query.
If you send the query without specifying a parameter
(:GPS:REF:ADEL?), the present antenna delay value is returned.
If you send the MIN parameter (using :GPS:REF:ADEL? MIN),
the command returns the minimum value currently available. If you
send the MAX parameter, the command returns the maximum value
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 Receiver assumes that <numeric value> is unscaled
(that is, Volts, seconds, etc.)
For example, the following two commands are equivalent:
:GPS:REF:ADELay 100 NS
:GPS:REF:ADELay 100E-9
Suffix Elements
Suffix elements, such as HZ (Hertz), S (seconds), V (Volts), OHM
(Ohms), PCT (percent), and DEG (degrees) are allowed within this
format.
