Hi folks. This is very much off-topic, but I know several people here use this sort of stuff either at home or at work. I've picked up one of the Prologix GPIB-ETHERNET bridge boxes, and I've been writing an instrument control library in the R language to control GPIB-interfaced instruments via the Prologix unit. I've been writing instrument drivers like a madman; these are the ones I have working so far: Standalone: HP 3325A synthesized function generator HP 3458A 8.5-digit multimeter HP 54111D digitizing oscilloscope HP 70900A spectrum analyzer HP 8505A RF network analyzer VXI: HP E1406A and E1301A VXI command modules E1411B VXI digital multimeter E1416A VXI RF power meter E1445A VXI arbitrary waveform/function generator Racal 3271 VXI RF signal generator This is amazingly powerful stuff when combined with the mathematical, statistical, and graphical plotting capabilities of R. I've started a mailing list for discussions amongst people using the Prologix units (not restricted to my work with R), and our efforts to get them running with different instruments. If you're interested in that stuff and want to be put on that list, drop me a note privately and I'll add you. -Dave -- Dave McGuire, AK4HZ New Kensington, PA
