Agilent Technologies 34401A Quick Start Tutorial

Connecting the 34401A to a PC using Agilent Connection Expert
Agilent Connection Expert (ACE) is an Agilent IO Libraries utility that configures the IO interface between the 34401A
and your PC. The IO Libraries are contained on the Agilent Automation-Ready CD or may be downloaded from the
Agilent Developer Network website at: http://adn.tm.agilent.com.
1. Install the Agilent IO Libraries on your PC and connect a GPIB cable between the PC and the 34401A.
2. From the PC taskbar, click the Agilent IO Control icon
and select 'Agilent Connection Expert' from the menu.
3. Select the PC's GPIB interface and select 'Add Instrument'
from the Connection Expert menu bar.
4. Select the GPIB0 interface and then select the
34401A GPIB address (factory setting = 22).
5. To verify the IO connection, open 'Interactive IO'
and send the *IDN? command to the 34401A by
selecting "Send & Read".
6. Use the 'Options' tab to increase the timeout period
for commands with execution times > 5 ms (e.g. *TST?).
