[dsg-hdice] HDiceNMR2 and/or Zurich lock-in amplifier availability?

[thomaso at jlab.org]

Hi Tyler,

Xiangdong is currently ramping down the magnetic field to zero so you can
play around with the heater switch.  He wanted me to tell you if you need
to change the field during your test, please don't exceed 0.25 Tesla or 5
Amps.

Xiangdong just let me know the field is now zero as of 3:45PM.  You are
free to test now.

Best Regards,
Tom

>> Hi Xiangdong and Tom,

>> If the Zurich lock-in amplifier is, I'd look at the CSV to H5 conversion

>> Hi Xiangdong,
>>
>> I logged on to HDiceNMR2 and added a version of the Oxford IPS power
>> supply program Peter had to the fsNMR project. You can open it from the
>> fsNMR LabVIEW project. A screenshot is attached with the new VI circled.
>>
>> After opening it, you'd just need to set the GPIB address to match the
>> power supply.
>>
>> I also ran the data review program for the ~400 cycle run with no
>> issues.
>> I was able to see all ~400 cycles after zooming out on the plots.
>>
>> Just a side note, the cycles aren't listed in the review program in
>> numerical order since LabVIEW sorts it "alphabetically". This can't be
>> changed since that behavior is just how LabVIEW works.
>>
>> If you have any issues with the Oxford IPS program or the data review
>> program, let us know and we'll take another look.
>>
>> I am now logged off of HDiceNMR2 so you can continue your testing.

>> Hi Tyler,
>>
>>
>> Here are my questions for today:
>>
>>
>>
>> 1.    What’s the maximum number of traces can bae reviewed for each
>> session?
>>
>>
>>
>> 2.    The Oxford VI of IPS on the NMR2 rack PC is an RS232 version (we
>> seems not have the GPIB version any more in the HDice lab). Do you know
>> how to convert it to a GPIB, currently used by the field-scan NMR
>> program?
>>
>>
>>
>> 3.    What’s the status of the program for controlling Zurich Lock-in?
>>
>>
>>
>> 4.    Is there any way to save the offline processed signals to the
>> format
>> which the Lock-in amplifier can recall as background?
>>
>>
>> Thanks,
>>
