Hi I am trying to connect a Lock In Amplifier - Manufacturer: AMATEK , Signal Recovery 7270 DSPLock In Amp.I downloaded their drivers and labview codes to check interfacing of the device. When I run the main vi, it runs and shows no error code but the magnitude and phase data can not be read on the front panel (OUTPUT), which I expect it should read from the Lock In. I checked the block diagram,there is a sub vi called: initialize.vi which gives an error code: -1223 , LabVIEW: Instrument identification query failed. How do I get rid of this error. what does it mean? Lock is connected to MAX, it shows device is running properly and also the VISA interactive control worked fine. I am attaching the .llb file for this Lock In. Main vi (orginal by AMATEK)is saved by file name: SR7270 Front Panel-Single Reference Mode.vi I want to plot the Oscillator Frequency against the Osc. Amplitude but as OUTPUT is not showing a change in data, graph is also not showing any data. Can anyone please suggest what is going wrong in the vi.

Maybe the 7270 Lock-in Amplifier's driver is not right.you should completely remove the original error driver.Then install the right driver from AMETEK.
