Enable Remote Control of Test Equipment
If you are using the specified Tektronix DTG and AWG models, the TDSHT3 software can configure the connected test
equipment automatically as you run tests. If you are using another DTG or AWG, you must configure the test equipment
manually.
Use this procedure to:
H Connect the AWG and DTG for remote control
H Configure the GPIB address for remote control
You will need:
H Tektronix DTG5274, Tektronix AWG710
H Tektronix 7000 series digital oscilloscope
H National Instruments GPIB−USB−B with the included software, NI−488.2 for Windows
Install NI−488.2 for Windows
NOTE. If you already have NI−488.2 installed on your oscilloscope, ensure that you have the version and installation
parameters that are described in step 1. If you do not, then uninstall NI−488.2, and install it according to step 1.
1. Install NI−488.2 for Windows (ver−
sion 2.1 or later).
During installation:
2. Do not install NI−VISA.
3. Install the Measurement & Automation
