MTD200 MPEG Test Decoder User Manual
The MTD200 MPEG Test Decoder is fitted with an RS-232-C interface as
standard. The connector is located at the rear of the instrument and permits an
external controller to be connected. The instrument supports the Standard
Commands for Programmable Instruments (SCPI), version 1995.0. The SCPI
standard is based on the IEEE 488.2 standard and aims at a standardization of
device-specific commands, error handling, and status registers (refer to SCPI
Introduction on page 5–4).
Basic knowledge of SCPI programming and operation of the controller is
required for a clear understanding of this chapter.
The requirements of the SCPI standard on the command syntax, error handling
and configuration of the status registers are described in detail in the relevant
sections. Tables provide a quick overview of the commands implemented in the
instrument and the assignment of the bits in the status registers. The tables are
supplemented by a detailed description of commands and status registers. For the
description of the commands, a basic knowledge of the MPEG test decoder
manual operation is assumed.
All program examples for control via RS-232 are written in C for the program
package V24.Tools Plus from Langner.
The following brief operating instructions allow you to quickly put the instru-
ment into operation and to set the basic functions:
1. Connect the MPEG test decoder to the controller via a null-modem cable.
2. Set the MPEG test decoder (menu item SETUP/RS232) to 9600 baud, 8 bits,
parity NONE, 1 stop bit, and the protocol PACE.
3. Start a terminal program on the controller, and set it to the same protocol as
the MPEG test decoder.
4. Enter the following command sequence:
a. DISP:OSD:MODE ON
b. SYST:DISP:CONT STAT
c. CONF:MON:CONT CLEA
d. CONF:MON:CONT START
