ZVA/ZVB/ZVT Remote Control: Introduction

Remote Control: Introduction
The instrument is equipped with different interfaces for remote control:
•
A GPIB bus interface according to standard IEC 625.1/IEEE 488.1. The GPIB bus connector for
direct connection to a controller is located on the rear panel of the instrument.
•
Instruments connected to a Local Area Network can be controlled via the RSIB or VX 11
interface. Two connectors for LAN connection are located on the rear panel.
The GPIB Explorer is a easy-to-use program tool that allows you to obtain an overview of all
implemented remote control programs, test programs, compile and run test scripts.
This section assumes basic knowledge of GPIB bus programming and operation of the controller. A
description of the interface commands can be found in sections
GPIB Bus Interface and RSIB Interface
Functions , respectively.
SCPI compatibility
The analyzers are compatible to the final SCPI version 1999.0. Not all of the commands supported by
the instrument are taken from the SCPI standard (Standard Commands for Programmable
Instruments), however, their syntax follows SCPI rules. The SCPI standard is based on standard IEEE
488.2 and aims at the standardization of device-specific commands, error handling and the status
registers.
The requirements that the SCPI standard places on command syntax, error handling and configuration
of the status registers are explained in detail in the following sections. Tables provide a fast overview of
the bit assignment in the status registers. The tables are supplemented by a comprehensive description
of the status registers.
Reset values
In contrast to instruments with manual control, which are designed for maximum possible operating
convenience, the priority of remote control is the "predictability" of the device status. This means that
when incompatible settings are attempted, the command is ignored and the device status remains
unchanged, i.e. other settings are not automatically adapted. Therefore, GPIB bus control programs
should always define an initial device status (e.g. with the command *RST) and then implement the
required settings.
GPIB Explorer
The GPIB Explorer is a easy-to-use program tool that allows you to obtain an overview of all
implemented remote control programs, test programs, compile and run test scripts. The program can be
opened from Windows XP's start menu:
Programs – R&S Network Analyzer – GPIB Explorer or by
starting the executable file
iecwin32.exe
in the program directory of the network analyzer (e.g.
C:\Program Files\Rohde&Schwarz\Network Analyzer\Bin
) .
After the GPIB Explorer is started, the interface for the connection to the instrument can be selected in
a dialog:
