I do not know your model and firmware.

Also you did not tell what EasyScope version you have.
There is two totally different EasyScope softwares. EasyScopeX    and EasyScope|somenumber|
Main thumb rule is: If your oscolloscope menu have USB selection USBTMC you need EasyScopeX

SDS1000DL/CNL/CML User Manual V1.2,  pages 106 - 110. There is instructions.

As far as I know, NI-VISA version  5.1.2 is compatible.
No need huge full package, only small runtime is enough.


-------------
Screen  image (BMP format) you can of course save directly to USB stick.
 Just connect FAT32 formatted usb stick to front panel and push "PRINT".

If want save some other things to USB. Push SAVE/RECALL button.
In menu select "Save to" = FILE
In menu select "Type" you can select Setups,  Waveforms, Picture and CSV  (also there is selection for recall factory settings)
Then there is "Save" and "Recall" menu.. where you continue (I think menu is self explanating)
-----------


Note for PC communication becouse I do not know how is your model default or settings: Go to UTILITY menu.
Page 2/4
There is "Back USB" selection.
Look that you can select between Printer / USBTMC. If it was other change it to USBTMC.  Wait 15 seconds. Shut off scope and then boot agen. 


If you have done many kind of failed installations and also windows have done some crap usb istallations etc hassle. I will recommend  first clean all installations related to this case  and then follow instructions for just your EasyScope version.

I have used XP for all testings (becouse I test every single unit before sell) and it works.

I hope Siglent write better instructions and exatly explanation what version to use with what oscilloscope version (FW version).
(example older FW's did not have at all USBTMC. There was selection Printer/Computer  and in some equipments USBTMC/USBRAW)

Some links for some manuals and Ni-Visa can find also here.

Dear friends, good afternoon!
Excuse me if I jump-in on this thread just to ask you a question about Siglent SDS1102CML.
Since I would by a new one by china (€324 shipping included) I would kindly ask you if you checked the "frequency meter" function in a HF typical maximum range. So, for example, on 28 MHz (28.000.000 MHz).
If you put in a 28 MHz sinusoidal signal, how DSO measure it? What does appear on display? I'm afraid if it shows, for example, 28.0001 MHz, that should be not good for my purpouse.
I need to calibrate/set-up oscillators on the range (7-28 MHz) for CW (Continuous waveform modulation of radio-frequence, Morse Code in other terms). So I need a precision of 20Hz (twenty Hertz), no more.
So, again, is there anyone can have this test for me?

Thank you very much indeed.
I appreciate the time you will spent to answer to my question, and excuse me for this not perfect written english ..... anyhow better than Chinenglish!  :-DD

Best wishes from southern Italy.

Roberto.

By finchinglish ;)  Just simple answer.

It do not meet your needs about frequency measurement accuracy. (and around same for also other this class of oscilloscopes, Owon, Rigol 1000E, Hantek etc)
Its accuracy is least 1:100 what you need.


No need test. It read in datasheet.
If one test it is just random individual unit, some unit may be "accidentally" perfect but also tomorrow it may have other result..


This separate frequency counter what display appear bottom right corner of display.
Specs sheet tell (typical) accuracy +/- 0.01% (+/-100ppm).
With 20MHz  it can show up to +/- 2000Hz wrong and still inside specs. 

It is cheap ordinary oscilloscope, not frequency meter.
(but of course this separate freq counter is nice also in oscilloscope use becouse it measure frequency by counting trig line)

Also there is not any adjustment for internal frequency reference. It is just with its (oscillator component) factory default. But if some really want, it can modify (change reference, good 100ppb or better class TCXO or OCXO.  But, then it can ask, is is clever if think this tiny counter functions and other things, (example resolution. It have 6 digits. 20MHz least significant digit is 100's Hz.)

Automatic or cursor measurement from displayed captured waveform is of course much much more inaccurate.

--- End quote ---

Eh. The CNL and CML are very different - the CNL does not have deep memory (only 40kpts), thus cannot sample at high rates over slower time bases. The CML has 50 times more memory to fit sampling in over the same time base. Did you check the Acquisition menu to see what the sample rate was? Switch to DOT mode to show the actual sample dots. Also switch off sin/x interpolation.


--- Quote from: johansen on September 19, 2013, 09:18:42 am ---at 500MS/S per channel , it should capture 25 samples per division per channel.
not so. in fact, you might be able to say it is capturing 10 data points per division, or it can't tell the difference between the LSB.

--- End quote ---

Verify that by checking the Acquisition menu and placing into DOT mode.


--- Quote from: johansen on September 19, 2013, 09:18:42 am ---note the decay rate and you should see something is seriously wrong.

What should it be?

roberto.pietrafesa:
Dear friends, thank you very much indeed for your explanations. These are very useful for me.
I will consider what I have to buy now.
Again, thank you and have a good luck for all!
I'm involved in built (DIY - Do It Yourself) HF kits, so principally up to max 30 MHz.
So now I would like to buy a SIGLENT DSO, since I like the possibility to save data on USB and after analyze these data on PC. But I'm not sure if I have to buy:
1)  a 100MHz or 60/70MHz DSO
2) a CNL/CML/CFL/DL type

The price differences are up to 120€. That is not a problem to spend much, but if I save about 100€, I can buy a good used frequency meter, so that I can complete the instruments set I need (I just have a FLUKE 87V DMM).

I don't want to buy a "better" DSO that I will pay more but it is not needful for my purpouse.

Thank you for your further suggestions.

Sincerely,
Roberto.

Roberto.
