Siglent SDS2000X HD, 12bit, 2GSa/s high definition oscilloscope serie.

[egonotto]

Hello,

now my SDS2XHD-BND has also arrived. Getting the licenses took some work. When I plugged in the USB dongle, I had problems because my SDS2104X HD crashed.

When installing the SDS2XHD-BND LIC files ?

Hello,

no, after I had installed the licenses and wanted to try out the USB stick on the other USB port. Then it crashed.

Hello,

in segmented memory mode I always get less than 100 Mpts/channel with four channels.

Am I doing something wrong?

According to 2N3055 you get much more with the SDS3000X HD: "It is 159 Mpts with 1Mpts length, per channel". With my SDS2104X HD I only get 97 Mpts per channel

With my SDS2104X HD I only get 97 Mpts per channel

"Record length up to 200 Mpts/ch, 400 Mpts in total for all 4 channels"

Correct however it need be pointed out the 200 Mpts is available to a single channel or when 1 channel is on each ADC and as each ADC has 200 Mpts available this will be divided down to 100 Mpts when 3 or 4 channels are in use.

Yup, but it's like they say: why type something out when you know Rob will do it for you? 😉😉

[mawyatt]

Yep, Rob is immensely valuable to the entire Siglent community, helping everywhere well out of his physical area of responsibility. We all are deeply indebted to Rob for his continual help and guidance with Siglent products

Folks considering various equipments should consider the Built-In Siglent" help Rob represents here

Best,

All true, but Rob helps with non-Siglent stuff too. Don't tell Siglent tho. 😉

Hello,

many oscilloscopes from other companies have much more segmented memory than in non-segmented mode. E.g. R&S RTB, RTM, RTA, MXO 4, MXO 5, Rigol DHO1074, Micsig MHO3, Cleverscope CS328A.

Well it's not like I didn't know what you meant so only added clarity for other readers that may not be aware of the acquisition system configuration in these models. 
Not all work like this......

That's true, but you're listing some scopes that cost significantly more (10x to 30x more!!), and some scopes you should recheck the datasheets for.

[KungFuJosh]

I'm procrastinating going to bed, and decided to waste some time comparing those models:

Memory Depth:   
CS328A: This seems to have the worst specs, but they list them oddly. Maybe 4 Mpts? Bueller?
MHO3: 360 Mpts (1 ch, or 180Mpts for 2 channels, etc.)
DHO1000: 50 Mpts(100M opt)
RTB2000: 20 Mpts
RTM3000: 80 Mpts
RTA4000: 200 Mpts
SDS2000X Plus: 200 Mpts (per ADC)
SDS2000X HD: 200 Mpts (per ADC)
MXO 4: 400 Mpts/upgradable to 800 Mpts
MXO 5: 500 Mpts/upgradable to 1 Gpts

Anybody see anything missing or inaccurate?

Thanks,
Josh

[egonotto]

.... and some scopes you should recheck the datasheets for.

Hello,

which scope do you mean? Perhaps MXO 4 or MXO 5?
RTB, RTM and RTA have far more than twice as much segmented memory. RTA has about 2 GSa segmented memory.
Cleverscope CS328A uses double buffers and makes the second buffer available for segmented memory.
The MHO3 has about 2 times 860 MSa of segmented memory.
If I remember correctly, I have more than 300 MSa of segmented memory in my DHO1074.

SDS3000X HD 400 Mpts

SDS6000A      500 Mpts/ADC
SDS7000A      500 Mpts 1 Gpts option.

You're comparing different things I (and Rob) listed memory depth per each respective datasheet. That's to be compared to the 100Mpts per channel when all 4 channels were active on the SDS2000XHD.

This is the memory depth spec in the DHO1074 datasheet:

Hello,

I am referring to this posts.

I am concerned here with the segmented memory.

The non-segmented memory is in the data sheet and is also present in the device.

I am disappointed that my SDS2104X HD has so little segmented memory.

Presumably Siglent also uses double buffers and could use this for segmented memory.
Picoscope does it the same way. In Run mode you only have half the memory.

Oh, it's way past my bedtime, I missed that part. Somebody else should chime in on the segmented memory comparison. I find it hard to believe that those other scopes are better based on the memory depth comparison, but I don't really know anything about comparing segmented memory and regular memory depth.

Hello,

the RTB2000 from R&S is particularly striking. It has 20 MSa per ADC, but you can have 16 segments with 20 MSa in segmented mode.

"
record length: 20 Msample
segments (up to): 16
total memory (per channel): 320 Msample
"

I have not found any information on the size of the segmented memory in the Rigol and Micsig data sheets. I can only provide the data from my devices.

Best regards

I also experienced some strange behaviour when installing the licenses from the bundle on my 2104X HD.

I had a 10MHz sine wave connected to CH1 (edge triggered, 50Ohm input set, 2Vpp signal) and it was 100% stable on the screen.  I proceeded to install the licenses from a USB stick (which seemed to install fine), but at completion of the install, the trigger on CH1 was completely lost. No matter how I tried, I was not able to get the scope to trigger properly again on the 10MHz signal.  Only after I rebooted the scope was everything back to normal again.

[Martin72]

I would describe this as normal, it has to be initialized once by a restart.

Yes, it seems so.  Not a big deal, just unexpected (to me as a new Siglent user).

[Performa01]

We normally install the license keys once and then just forget about them.

Yet it just so happens that just recently I decided to bring some of my scopes up to date and install the missng licenses (e.g. of options that haven't been available back when I got the instruments), therefore I remember very well how it goes.

The instrument prompts you to do a restart after each and every license key that has been accepted. You can ignore that prompt and install another license immediately, yet after entering the last key you should perform the requested restart.

I had the USB stick loaded with the 8 license files that were included with the LA bundle, and in my case there definitely were no prompts between each license.  They all were installed automatically one after another once I started the installation.

That is how it works. Same with some other models with genuine .lic files in USB stick. (done it for some customers who have purchased scope with optional licenses)

Well, then there is a problem with the USB-installation method. Of course we would not expect a restart prompt after every single key, but after the last key from the USB-stick has been processed.

I'll clarify that with Siglent.
