how fast we can Retrieve waveform from scope

[RBCHAVAN_77]

We are using GPIB-PCI  card for acquiring wave form from Tektronix TDS 2024 scope using CURVE? Query. We are able to get all the 2500 points and plot the wave form but it takes around 2-3 seconds to do these process to write the query and read the wave form data. Can we reduce the time to acquire the data or can we write the CURVE? query command and do some other opeartion like to read the data from other device in the program and again after 2-3 seconds read the response for CURVE?. How can it be done and where that data(waveform - 2500 points) will be stored.  We were using CWGPIB ActiveX control. Also can we use CWSERIAL ActiveX control for reading the 2500 points of data at a time? what is max buffer size that can be used in CWSERIAL ActiveX control? What is the typically response time for *IDN for any instrument for GPIB and SERIAL data access?

Hi

The time is the time the scope needs for sending the curve data.

In LabVIEW you could use a parallel loop to read the data and do some intelligent stuff in another loop.
