Hello Frank
OK, I just hooked three instruments in parallel to my 10V Geller SVRT
All three instruments are hooked up to BenchVue via Network Cable on a 1 gbit network
This is what I get for collecting 1 Mega Samples at fastest acquisition time:
34410A
10.024 KSa/sec
Time for collecting data: 99 Sec
344110A
50.118 KSa/sec
Time for collecting data: 19 Sec
34470A
25 KSa/sec
Time for collecting data: 40 Sec
I can send you the exported Excel files, if you like.
It is interesting how the screen of the three instruments are changing to just show the word: "DIGITIZING"
Is this what you wanted to know?
Or do I need to do some more test's
Hello HighVoltage,
sorry that I discovered your post and answer so late!
No, that's not yet the crucial test, because with these settings, both instruments (411A and 470A) will handle all the digitizing fully inside internal memory. If you increase the number of samples to more than 1MSa for the 411A, and more than 2MSa for your 470A @ 50Khz also (has to be manually set to digitizing at the instruments panel!), then you might notice a delay and even data loss, as at least the 470A is not able to transfer data fast enough over the bus, at first due to the ASCII format.
The 411A may have a dedicated state machine, or faster SW code, to handle that fast transfer to PC, as specified in its manual (*)(lacking for the 470A!), and might also transfer in 4 byte / 8 byte format, which would be 4 or 2 times faster, than with the ASCII transfer.
Would be nice, if you could test again with 50kSa/ sec and 4MSa for both.
THX!
Frank
PS: I assume, that both instruments don't have the possibility to transfer data directly to PC, omitting the buffer.
This method is available on the 3458A (@ >100kSa/sec), and allows real-time digitizing.
