I meant ch1 ch2 on a usb key.
can someone please export two specific csv's from an Owon?
one when Owon ch1 enabled, no signal connected, AC counpled, timebase set to 500us/DIV, 10Mpoint, 1GS/s and the first volt/div with no bw reduction, so i think 5mV/DIV. And then second one with same settings but ch1 set to gnd.
Just wondering, how did it pass the EMI test?

I don't know of a way to export CSV files from the Owon. The attachments are binary files (.bin renamed to .hex) with the scope setup as you specified and the corresponding images so you can see what the waveforms looked like. I assumed that by no signal you meant nothing connected to the BNC. Hope that helps.
There are many convertors "bin to csv", so there is no any problem with the bin files.

I'm out from work and can not do it now but with this computer here was old Owon PC soft .11.
With Owon PC software you can convert bin file to .txt, .xls and .csv.
If there is twi channel in use then there is Ch1 and Ch2 selection. If convert both it go to same file
something like this. (this is not from example image how to use PC soft)
In example image, there is 1M memory Ch1 and it produce around 13M .csv
(it was only Owon .bin file in this computer what I find)
(from Owon PC soft example files becouse it have two channel together)
First some information bytes
sample no,Ch1,Ch2
1,-600.00,3440.00
2,-600.00,3360.00
3,-600.00,3440.00
4,-600.00,3360.00
5,-600.00,3440.00
6,-600.00,3360.00
7,-600.00,3440.00
8,-400.00,3360.00
9,-600.00,3440.00
10,-400.00,3360.00
...
In PC soft, (of course first open stored .bin file from PC or USB memory and then... first open View, select data table, select sequence, Ch1 and/or Ch2 and then Save as...
Select file type and save. (10M bin to .csv take some time... and result is over 100M if one channel)

TomC, he asked the first scale of Volts (2mV/div or 5mV/div). For what I remember, the SDS limited automatically the BW at these scales. Set the menu "Probe Set" to 10X and repeat the measurement.

mlhstock, 160mVpp is in the normal range for scopes prior to the June production with modified PSU & Adapter boards. So provided you did the test using the setup guidelines suggested in recent posts, your scope's performance in this respect is similar to what other of us have been experiencing. On my scope, before I added some ferrites, the GND noise level was in the range of 145mVpp.
However, as I understand it, you were promised a scope from the June production. If I was in your shoes, I would try to convince the dealer to stand by their promise. I would state the facts without getting angry, and elevate the complaint to higher management if necessary. As a last resort, I would complain directly to Owon, explain the circumstances, and try to get at least new components to get my scope up to date.
I bought mine from a dealer on E-Bay (SMTZONE) that shipped the unit directly from Hong Kong. Mine is from the new June batch and is very good.

I bought one recently on E-Bay (SMTZONE) with serial SDS7102 1312 517
Is this a new batch?
As I am a newbe I dont know what to think. Where is the explaination of the spring test?
What kind of capacitor is the 1000pF SDM: ceramic, metal, etc.?
See attached the noise test as described in msg #1332
TomC, you just received the shipment of Owon...we 'll waiting for the tests!

As far as I know the first 2 digits of the s/n, in this case 13, is the year (2013 in this case). The next 2 digits, in this case 12, is the week of the year. So your scope was built during the 12th week of 2013. Not quite the June batch, but scopes built during this period have been reported by other members to have lower GND noise than earlier batches. Member dgmoore78@yahoo.com's scope is 1319, so it was built during the 19th week of 2013, which is not quite June, but it's very close.
Here is another ground test.

The new PSU board and the modified Adapter board are in. In general, I'm disappointed with the performance of this upgrade.

As TomC you said, this noise level is a little higher than average.
My opinion is that noise is high if you set the schema of probe cable as we told you. If you set the schema of probe cables "free" and straight, OK this is an average noise.
(sorry for my english...)
