Communicating with Remote Instruments
The TLS 216 Logic Scope can connect into a system environment, so you can
control it remotely or exchange measurement or waveform data between it and a
computer. This article explains how to prepare and setup the logic scope for
control and operation over the IEEE Std 488.2-1987 (GPIB) interface.
To Prepare for Remote Operation
To transfer data between the logic scope and other instruments over the GPIB, do
the following tasks to make sure the instruments support GPIB protocols and
observe GPIB Interface requirements.
Make sure the instruments to be connected support the GPIB protocols. These
protocols cover:
H
Remote instrument control
H
Bidirectional data transfer
H
Device compatibility
H
Status and event reporting
To simplify the development of GPIB systems, include instruments that use
Tektronix defined codes and formats for messages that travel over the GPIB.
Each device that follows these codes and formats, such as the TLS 216 Logic
Scope, supports standard commands. Use of instruments that support these
commands can greatly simplify development of GPIB systems.
To prepare to connect the logic scope to GPIB networks, read and follow these
rules:
H
Connect no more than 15 devices, including the controller, to a single bus.
H
Connect one device load every two meters (about six feet) of cable length to
maintain bus electrical characteristics. (Generally, each instrument represents
one device load on the bus.)
H
Do not exceed 20 meters (about 65 feet) of the total cumulative cable length.
H
Turn on at least two-thirds of the device loads present when you use your
network.
