Keithley 6517 real time measurement and sampling frequency

Hello,

I am using keithley's 6517 Electrometer. I have connected this instrument to my PC via GPIB.I am doing dynamic pressure measurement and I need to sense how charge or voltage changes with respect to time during dynamic pressure applied via piston to a liquid.
I have two queries
a) I want to know the sampling frequency or time interval of measurement of this instruement as dynamic pressure pulse lifetime in my application is only 3ms. I want to read changes in charge or voltage in micro second time interval. Is it possible with this 6517 instrument?
b) In addition, I am using labVIEW 2012 and using "keithely 6517 example.vi" program that comes with driver as an example.Is it possible to create a graph which shows real time changes of charge with respect to time?

PS: I have attached labview file which I am using now

Any kind of help or suggestion would be appreciated.
Thank you

Have you read the manual or looked at Keithley's web site - http://www.keithley.com/products/dcac/voltagesource/application/?mn=6517B? It clearly states the sample rate.

Hi,

 

thanks

 

Yes I saw it..it can read 425 reading per second..means sampling rate is around 2.4 ms

So Its impossible to get micro second sampling rate

Unless you're wanting to sample every 2400us, then yes it's impossible to get a sample in microseconds.  The device tells you that from the start.

Thanks

 

And how to get real time graph of a charge or voltage in labview

You pass an array of values to a graph. If you acquire a single point at a time, you pass the scalar to a chartinstead. Show where you are stuck.

Hi,

 

finally I did it. I made it very complicated

Hii pateIMIKES,

 

I am trying use your Labview program attached (6517.vi) in previous message but SUB-VIs of following were missing while running this program,

1. Keithey 6517 coulombs config.vi

2. Keithley 6517 Single read.vi

 

Can you send the Sub-VI files or Driver files you used for this program. Looking forward your reply.

Thanks in advance.

 

Warm Regards,

I am running into an issue with the code as some sub-VIs are missing can you send me these 

(Keithey 6517 coulombs config.vi) & (Keithley 6517 Single read.v). I'd really appreciate it.
