Chapter 1 Outline
1-2.
1.1 SCPI Remote Control
SCPI (Standard Commands for Programmable Instruments) is a
standard concerning the command syntax and data structure of remote
control commands developed for measuring instruments.
The MS9740A Optical Spectrum Analyzer provides command messages
that conform to the SCPI standard syntax. However, it does not support
the status registers and required command messages that are specified
in the SCPI standard.
1.2 Message Format
For general description of messages, refer to 2.5, “Message Format” in
the MS9740A Optical Spectrum Analyzer Remote Control Operation
Manual
.
SCPI messages have a hierarchical structure separated by colons as
shown in the following example. Lowercase characters and sequences of
characters enclosed in square brackets can be omitted. The behavior of
MS9740A is the same between the following messages:
:DISPlay[:WINDow]:TRACe:X[:SCALe]:STOP
:DISP:TRAC:X:STOP
A query command has the question symbol (?) appended to the string.
Example:
:DISPlay[:WINDow]:TRACe:X[:SCALe]:CENTer?
:SYSTem:INFormation?

2.1 Preparing Equipment
The following MS9740A is required to perform remote control.
•PC
•Ethernet interface
•Ethernet cable
•GPIB interface (when installing Option 001)
•GPIB cable (when installing Option 001)
•VISA
•Program development tools
Ethernet Interface
Prepare the interface that conforms to the following specifications:
10BASE-T
100BASE-TX
1000BASE-T
Furthermore, use the cable corresponding to each specification.
GPIB Interface
Procure the GPIB interfaces that conform with IEEE 488.2.
VISA
When controlling the MS9740A remotely using the Ethernet port, a
VISA*1 driver must be installed in the PC controller. We recommend
using NI-VISA™*2 from National Instruments™ (NI hereafter) as the
VISA driver.
Although a license is generally required to use NI-VISA™, the licensed
NI-VISA™ driver is provided free-of-charge for use when performing
remote control*1,*2of a MS9740A unit in which the MS9740A-001 GPIB
option has been installed.
The NI-VISA™ driver can be downloaded from the NI website at:
http://sine.ni.com/psp/app/doc/p/id/psp-411
Be sure to comply with the NI license agreement for the usage and
license scope.
Be sure to uninstall the NI-VISA™ driver when disposing of the
MS9740A or transferring it to a third party, etc., or when ceasing to use
NI-VISA™.
*1: Although the NI-VISA™ driver itself can be downloaded
free-of-charge from the web, an implementation license is required
for legal reasons if some requirements are not met. (Check the NI
web page for the detailed requirements.)

2.1 Preparing Equipment

Before Use
*2: If these requirements are not met, permission is not granted to use
NI hardware and software and an NI implementation license must
be purchased. However, since the MS9740A-001 GPIB option
incorporates NI hardware (GPIB ASIC), the NI-VISA™ driver can be
used free-of-charge.
Glossary of Terms:
●VISA: Virtual Instrument Software Architecture
I/O software specification for remote control of measuring instruments
using interfaces such as GPIB, Ethernet, USB, etc.
●NI-VISA™
World
de facto standard I/O software interface developed by NI and
standardized by the VXI Plug&Play Alliance.
Trademarks:
●National Instruments™, NI™, NI-VISA™ and National Instruments
Corporation are all trademarks of National Instruments Corporation.
Program Development Tools
Prepare some tools for developing and running programs for performing
remote control. Refer to the VISA and Interface manuals for the
specifications required by the program development tools.
PC
The PC must be able to run the GPIB interface, VISA and program
development tools.

2.2 Connecting Equipment
2.2.1 Connecting Ethernet
Connect the Ethernet connector on the rear-panel of the MS9740A and
external devices using LAN cables.
Use a LAN crossover cable to connect the MS9740A and an external
device. Use a network hub when connecting to multiple external devices.
Note:
Check the network settings of the MS9740A when connecting to
multiple external devices
Figure 2.2.1-1 Sample Connection with One External Device
Figure 2.2.1-2 Sample Connection with Multiple External Devices
Note:
External devices may experience difficulty in communicating with
the MS9740A, depending on the status of communications between
them. A LAN crossover-cable connection is recommended to ensure
communication stability.
