lecroy scope save waveform works slowly

[Andranik_]

Good day everyone,

I am using Lecroy 6051A scope and it seems to me, that saving waveform works too slowly. I have written a program for my Lecroy and there have a loop with N=100 to save 100 waveforms. It takes around 20 seconds to do so, which, as it seems to me, is too much. I want to be able to save at least 20 waveforms in 1s. 

I have attached my vi. I use 1 channel, timebase was 200 ns/div (250Ms/s). I was advised to use VICP descriptor instead of TCPIP, as it should work faster with VICP

I was trying to delete all the vis in my programm except for those in the 'for' loop, but still it was almost 20 seconds to save 100 waveforms. I am new in working with Labview, maybe I am doing smth wrong, could anyone help me please?

Your timebase is irrelavant. How many datapoints per waveform?

20 seconds for 100 waveforms is .2 sec per waveform, that is not bad for a scope!

The good question is how much data points indeed and what is your tcp/ip speed?

Hallo Albert, greetings from Germany,

here I attach one of these 100 waveforms in csv format - there are 500 points. Actually in this file its only amplitude points, but I can save amplitude with time, but the saving time doesn't change much. Do you think its ok?

I am not sure how to measure TCP/IP speed as you say. But I used speedtest.net to measure upload speed, which is 7.44 Mbps and download speed = 6.17 Mbps

hi nyc,

I have 500 points for the waveform

That seems a reasonable speed for an instrument.

Ethernet can be faster but probably the scope is at its limits.
