GPIB how to read burst of samples from HP E1326B with E1347A multiplexer

[yin_the_novice]

I am trying to read a collection of samples from a single channel with a sampling rate of 1kHz every time a trigger is activated. My problem is that although I have a lot of example code in text format, I am not sure how to configure the HP E1326B to change the number of samples read each time it is triggered using the Labview pallete. There is no effect when I change  the Sample Count setting on the Configure trigger Vi, although i can get an arrray like i want by setting multiple triggers. When I set a single trigger and a high sample count on the Configure trigger Vi i still only read one sample per trigger. I know I am supposed to have code similar to :

160 OUTPUT 70903;"  SAMP:SOUR TIM"

170 OUTPUT 70903;"  SAMP:TIM 0.001"

180 OUTPUT 70903;"  SAMP:COUN 100

The problem is when I use multiple triggers the sampling rate is slow. Is anyone aware of how to set the sampling rate on this DMM and collect multiple samples per trigger? Also, is there a way I can type text commands to the instrument through labview ?  I have attached my test code for reference. 

Thanks !

Yin,

I put together a simple example of some code which should be similar to what you need. It basically allows you to write a series of commands to the GPIB device, then read off the data. I used some of the example code from page 45 of the user manual for that device found here:

Heres a code snippet: 

Let me know how that works for you!
