Data transfer

[goh toh meng]

Using a Tektronix TDS7000 series scope, I want to transfer scope data in .CSV or .TXT out from the scope into an external PC via GPIB.

From the scope the acquired data has an accuracy of 5 decimal points.

I want to know, when I transfer this data using an NI GPIB card connecting my PC and the Scope. Will I see a truncation/rounding off of accuracy? say from 5 dp to 3dp?

GPIB does not truncate any data. GPIB is a byte-parallel bus that transfers one byte at a time from the talker to the listener. The data that the device sends will be exactly the same data that the controller receives.

I'm trying to transfer a waveform from a TDS7000 series scope in a .csv file.  I have a TDS7704B and I can save the image file as a JPEG but not the waveform as a .csv file. Here is my string inputs to NI VISA:

DATA:SOURCE CH1

SAVE:WAVEFORM:FILEFORMAT SPREADSHEETCSV

SAVE:WAVEFORM CH1 (DESTINATION AND FILE NAME)

EXPORT START

Have you get this working and will you share the code?
