connecting lock-in amplifier to USB-6009/6211

[cjdiet]

I am working on re-setting up a labview environment in the lab I work at. We are using a SR810 DSP lock-in amplifier and want to bring the data into labview. The labview code says that in the past we used a USB-6009 to read in data from the lock-in amplifier. The output ports on the lock-in are an RS232(DCE), a IEEE-488 port, and a preamp port. Is there someway to feed one of these outputs into the DAQ that we have. Thanks

The cheapest approach is rs232, no need for the 6009

We still have the USB-6009 and 6211 devices and would prefer to use those if at all possible.

If you have code, why aren't you using that? I don't believe for a minute that it actually used the RS232 or GPIB, though. The instrument has other outputs.

An RS232 or GPIB connection directly to the computer would be best, but if you insist on using the 6009, run a line from the CH1 outut BNC on the front panel of the lockin into the DAQ device. Note that this is a -10 to 10 V output and that the mapping to the actual LIA voltage depends on the sensitivity setting of the lockin (see pgs 4-2 and 4-12 of the 810 manual).
