I'm sending this a 2nd time since for some reason the 1st time I never saw it show up....
[ping test it is now 2:50] I'm going to upgrade an old HP instruments this winter and am looking for recommendations on a SBC that will run Linux. For those that are curious, the instrument is a HP 8401C Network analyzer. This instrument predated even GPIB and initially did not have any computer interfaces. Even when it did, it took a lot of external hardware. The other instruments are those required to provide a RF signal sweeper, or synthesizer, relay controllers, power supplies etc. All of which are GPIB based. Internally there will be the need to open/close relays, read switch setting, etc. all of which can be done from single I/O lines. Communication via Ethernet, UI will be on a PC. Device I/O requirements are: - RAM Don't know how much, programs will take very little, my guess less then 20 MB. - Disk. Solid state ? - Ethernet 10/100. 1000 Optional - Enough Parallel I/O to .. - Interface to 4 each 12 bit A/D converters. Data rate of a maximum of 200 K samples/second. Can be externally buffered with hardware FIFOs. - Create a GPIB interface. This interface does not have to a full GPIB, nor does it have to be fast. Just enough to set listeners such as a RF sweeper, synthesizer, relay controllers etc. - Interface to various parallel devices. Right now 16 output lines and 16 inputs are enough. These are slow devices. I/O be interesting to have - LCD interface on optional board ? _______________________________________________ PLUG mailing list PLUG@lists.pdxlinux.org http://lists.pdxlinux.org/mailman/listinfo/plug
