Read trace 1 (X) in SR850 lock-in amplifier

[Cordeoli]

Hi,

We have a SR850 lock-in amplifier connected to a HP 6632A power supply and both devices connect to a fiber puller.

We are using labview to automate the experiment and right now we are having problems with the labview program giving us the correct trace 1 value when the program runs.

The read trace driver for SR850 is included in our program but the final file, when opened, does not give us the trace 1 from the lock-in amplifier. In other words, the read trace driver is not reading the lock-in amplifier.

Could you please give us any help on this? Please let me know if you need any information from us to help us debug this error.

Thank you very much.

Hi Luciana,

Please reply with a little more information regarding your current hardware/software setup.  For example, what NI card are you using (PCI-GPIB?), what version of LabVIEW (2010?), what drivers (NI-488.2 version?), operating system (Windows 7?).

Also, are you using the 6632A driver from NI's instrument driver network?

Thanks!

HI Greg,

Answering your questions:

- we are using the GPIB cables

- the LabVIEW version is 8.6

- the drivers we use are for the Agilent 6XXX series and SR850.

- the operating system is Windows XP.

 The power supply we have is a HP 6632A, and the driver we used to test is the Agilent 6XXX series which actually worked ok for this device. I am not sure about the version, all drivers we downloaded were taken from the NI instrument driver network.

Please let me know if you need any further information.

Thank you so much for your help.

Hi Luciana,

Unfortunately, NI's resources are quite limited on this driver since it is not officially supported (according to the SR850 driver download page).  Do you have any problems running the examples provided with that driver?

Hi Greg!

We were able to solve the problem yesterday, instead of using the drivers we decided to use commands instead and it worked. It made the coding less cluttered and simpler.

Thank you so much!!!
