Here is my scenario:
* I am collecting data with "BenchLink Data Logger 3" from two units of "34970A".
* I tried to collect data over 24 hours ( data size will be smaller than 10 MB), and want to monitor the data anytime.
* Unfortunately, BenchLink Logger will lost connection to both 34970As (at different time) after a couple hours.
(although 34970As are still running by themselves)
* I know 34970A can run by itself without connection to PC.
* But when I tried to upload the data from 34970A, it reports that channel configurations are different from latest channel configurations on BenchLink Logger, how come?
Anybody has similar problems? any hint?
Thanks!

This is very strange. If you send the ROUT:SCAN? query to get the scan list, is it the same as you expect? The same as you have configured in BLDL? Have you queried for any errors (SYST:ERR?) after the connection is lost? Be sure to repeat the error query until "0,No Error" is returned as there can be multiple error messages in the error buffer. Try running the IO Libraries Connection Expert IO Monitor to capture a trance of all the bus traffic while BLDL is running. This should tells us what happens when the connection is lost. Are you using GPIB or RS232. A good GPIB to USB adaptor like the Keysight 82357B is generally more reliable than RS232. If you are using RS232, you might try a slower baud rate. 9600 is usually good. Hope this helps.
