What’s in This
Chapter This Chapter lists and describes the set of SCPI-compatible
(Standard Commands for Programmable Instruments) remote
commands used to operate the 5251. To provide familiar formatting
for users who have previously used the SCPI reference
documentation, the command descriptions are dealt with in a similar
manner. In particular, each sub-system's documentation starts with
a short description, followed by a table showing the complete set of
commands in the sub-system; finally the effects of individual
keywords and parameters are described. Complete listing of all
commands used for programming the 5251 is given in Table 4-1.
What is Required
To successfully use this instrument, the following conditions must
be met:
1. The instrument is installed (and detected) in the PXI mainframe.
2. Visa 4.0 or later is installed.
3. IVI driver is installed.
4. ArbConnection 4.3 or later is installed.
Installation of one of the IVI driver or ArbConnection is mandatory
and critical to the operation of the instrument as it places the control
dll in the appropriate directory. Installation procedure of the 5251
and its controlling software can be found in the installation chapter
of this manual. Even if you do not intend to use the IVI driver, nor
will you use ArbConnection, it is suggested that you install both
anyway and first operate the instrument through one of these
utilities to make sure the 5251 responds correctly to commands and
queries.
Both the IVI driver and ArbConnection are using built-in functions
that convert standard SCPI commands to machine code.
Knowledge of basic SCPI programming and concepts is required to
operate the instrument and hence the short introduction to SCPI
programming that is given below. If you are not sure what SCPI
programming is use the log file in ArbConnection and select the
show commands only; This will give you an overview on how
commands control various operations of the instrument.
Introduction to
SCPI
Commands to program the instrument over the GPIB are defined by
the SCPI 1993.0 standard. The SCPI standard defines a common
language protocol. It goes one step further than IEEE-STD-488.2
and defines a standard set of commands to control every
programmable aspect of the instrument. It also defines the format of
command parameters and the format of values returned by the
instrument.
