Test Equipment... yum!

Scope: LeCroy WaveSurfer 64MXs-B
Power Supplies: BK Precision 9130B / GW Instek PSP-2010 / Modified QCB4
with current limiting
Multimeters: Fluke 26 III / BK 5492B / Keithley 2002
DAQ devices: Several LabJacks - U3 and U6

All tied together through a PicoPC mounted to the back of a large
touchscreen display. GPIB stuff goes through a Prologix USB to GPIB bridge.
This allows me to automate when more complex measurements are needed. I'd
probably move over to a Raspberry Pi running the show, but a couple of
pieces of equipment don't have Linux support yet.
