Read a 'burst' of data from TDS 1002b using Labview with USB

[Rphennessy]

Hello,

I am trying to acquire a 'burst' of data using an external oscilloscope (Tektronix TDS1002B) connected by USB and using labview 8.6. I've downloaded the driver and I've made my own VI based on the provided VIs (see attached VI). I can manipulate both the horizontal and vertical axes with ease. My problem is that I can only seem to get 2500 points in one capture (no more, no less). I would like to set the number of samples to captured to  >2500 pts. This will allow me to achieve good resolution. It seems like this is feasable, but I am not familiar enough with the driver language to do this myself. Any / all help is greatly appreciated!

Tried reading the programmer's manual?

Maybe it is not a problem with the driver.

Thanks for the reply.

I'm sure it's not a problem with the driver - what I would like to know is how to manipulate the driver in such a way that the oscilloscope returns more than 2500 points in one capture. Any idea of how to do that?

Read the programming manual. Learn what the command is to do what you want. Modify the VI for that command.

This is exactly what I'm looking for - - I need the string that accesses how many points the scope caches. For example, I use the string ':HOR:MAI:SCA 0.000500;' to tell the scope to set the time base to 0.0005. I know that there must be a set term for setting the number of samples, I just don't know what that is. I'm not sure what programming manual you're referring to - could you please post a link?

:HOR:MAI:SCA 0.000500;

I don't know why this forum automatically replaced that with an emoicon...
