Description
A GPIB cable still ties together many production and QA test racks. The Keithley 2220G-30-1 power supply keeps that option, because its listing names both USB and GPIB beside two isolated outputs. Lost in HCM lists it for rental and sale and arranges service on request.
Dual rails for a GPIB-controlled rack
Automated test often starts with a controller, a switch matrix and a stack of instruments. Add this unit, and the fixture gains two powered rails from one slot. Each channel gives up to 30 V and 1.5 A, while the total reaches 90 W. Because the outputs stay isolated, the two rails do not share a return. The Keithley 2220G-30-1 power supply therefore suits a fixture with two separate loads.
Choosing the interface
GPIB suits a rack that already runs older drivers and cables. For a laptop on a bench, USB works better. The 2220G-30-1 lists both, so you can start on a laptop and move to the rack later. In contrast, the 2220-30-1 listing names USB only.
Typical places to use it
- End-of-line test cells, because a script can power the board under test.
- Incoming inspection benches that check small modules before assembly.
- University and R&D labs that automate repeat measurements.

What does the G in the model code add?
This listing names USB and GPIB, while the 2220-30-1 listing names USB only. Output ratings match: 30 V, 1.5 A per channel and 90 W.
Can I run it without GPIB?
Yes. USB is also named in the listing, so a laptop works for control.
How do I ask for a rental?
Send Lost in HCM your dates, site and accessory list. Price and availability come back individually.
