Siglent SDS2000X Plus

[thinkfat]

I measured a 10MHz Butterworth low-pass filter that is supposed to create a sine from a square wave by suppressing the harmonics and it's really nice being able to just set markers on all harmonics and then see how many dB the most prominent harmonic is below the carrier. The only grief I have that it seems not possible to set the vertical config to dBc instead of dBVrms or dBm. I get the absolute value of every marker and a simple subtraction addition gives me what I need, but it would nevertheless be more convenient to just have marker #1 setting the reference and then listing all other markers relative to marker #1.

YES! Found it! You can switch on a "DeltaAmpl" column in the marker list. This lists all markers referenced to #1! That's exactly what I was looking for.

SPL2016 logic probes shipped with SDS2000x+ seems very similar to Lecroy posted by tautech, thank you for sharing!

The LA set includes:
1. the PCIe interface cable to 2x 20pin parallel connector (2.54mm raster). All pins on one side of the PCIe are all ground, connected to ground pins on the 20pin connectors (10pin on one side plus 1pin on each end of the other side all grounds). There is 92kOhm serial resistance to be measured between the 8 active pins and and the PCIe active pins.
2. the 20pin parallel connector to single-wire probe cables. All grounds are pass-through, all acive pins have serial resistor 91 Ohm between probe and 20pin connector.
3. a box of probe adapters, same as on tautech photo

I recall someone saying the PCIe adapter use 8x coax ribbon cables. From the PCB photos published here, scope PCB includes LA comparators with threshold voltage adjustment. So it seems, the LA probe is passive only. This was only a quick check, so no warranty. Pls see my SPL2016 photos attached.

I made the same measurement on my MSO2072A La probe, i find 91.5 kOhms between each terminal and PCI-E plug,
and 150 Ohms between PCI-E plug and female header.
So, that seem quite similar to Siglent probe.

Yes but it is little surprise the LeCroy MSO probe similar when in fact they will be the same as LeCroy market a few Siglent products as their own. It's of greater interest Tek use very similar PCI-e socketed probes which might indicate they don't have concerns of limited mating cycles where in fact the contact loadings and data throughput rates for LA probes will vastly different to what's required for PCI-e cards in a PC Mobo.

Thanks for the measurements but:

This is not the conclusion I came to after buzzing some connections out.
Even the flying lead breakout sections seem to have active components inside and those with a better camera might like to take picks of how these pieces are constructed or better still, as mentioned before X-rays !

Well looky here, 16ch MSO probes from both LeCroy and Tek appear very similar:
LeCroy  Number   T3DSO2000-LS
Tek P6616 and some similar pt#'s
RIGOL RPL2316
I wonder who makes them ?   

Find some cheap busted ones from eBay and dissect/RE them ?

Have a look at the current probes….
Siglent, Rigol, R&S, Lecroy, Keysight and partially Tek....It´s all the same...

Bugs:

FFT Marker Table:
- Even when the switch for "Show Table" is on, the table is not shown unless you toggle the switch. Same for "Show Delta".
- When switching off the "Show Frequency", the "Delta" column is incorrectly labeled as "Abs.Freq" (screenshot)

I received my scope today. Three days after ordering from Germany. Excellent service. Sadly Miyagi's update method did not work. I get a refused connection when I try to TELNET in with Putty. The scope can see the startup.sh file that has the telnetd but I dont think its reading it on startup. Any thoughts?

Just a follow-up... I purchased a demo unit from WELECTRON in Germany and DHL charged me $53 in duties ($38 duties, $15 processing fees) for delivery tomorrow in the US.

What tariff code did they use? Mine is coming under 90302000 so no idea if ill be pegged yet as technically that code isn't listed but 90302010 is

I haven't received yet, so don't know what tariff code they used.  It was a 4% duty, so it is not the Made in China tariff which I think starts at 25%

I have not received any bill from DHL. Weird. Not complaining though. Man I love this instrument.

You dont get a bill from them like fedex... they will hold hostage your item till you pay lol

What's your import BOL say on it?

Yeah cant wait to get mine.. they just shipped it today

Also found this bad ass probe station setup thanks to their advert banner.. i got a similar one for soldering and under my microscope

I bought a full set of 4 scope probes and 8 logic probes from saelig

It's the 4003, right?

4015, it has the large base + 2 scope probes

then i added 2x SP100 probes so i have a full set and since i got this nice new logic analyser coming, i threw in two packs of 4005 so i can do 4x analog and 8x digital which is fantastic for me

I've been wanting a system like this for years now as i try not to litter my boards with a hoard of test points which get in the way of high density designs

[stafil]

Nice helping hands!!

Wow!   That is so cool!   I can imagine the probes moving by themselves in a cheesy SCI-FI movie!

I got mine today before i got the scope.. lol

Anyway its kinda like i thought, they are a specific impedance set by 100K / 18pF components and the wiring.  Your paying for controlled impedance

Now how many need that? all depends on what you are doing, if someone doesnt need it then anyone could rig something up using pci-e header for a few bucks

I debated it but my own laziness wins when its already in hand, i'd say most wouldnt need it unless you already know about controlling pcb material impedance and that's how far you are going and signal tuning / timing.. if not odds are you dont

I have only maybe two applications that fit that out of dozens of others where its not a critical parameter

Edit: another fun tidbit... you can track carrier flights on flightaware.. how cool is that.. watching my scope fly across the pond in real time

I think I discovered the rule (or the symptom) of an upgraded SDS2000X+ becoming a 2354X+ (w/ 500MHz) or a 2504X+ model:

It's all in the S/N:     

SDS2Pxxx3Rxxxx  will turn into a 2354
SDS2Pxxx4Rxxxx  will turn into a 2504

3 or 4 AFAIK is just part of the production quarter/date code

I don't like the way this scope is drawing the waveform: why it cannot draw a smooth trace?

[TK]

10-bit resolution acquisition bug???  What am I missing?

@8-bit resolution, Pk-Pk is 1.3267V


@ 10-bit resolution, Pk-Pk is 1.014193V


EDIT: Found the answer in the manual... BW is limited to 100MHz in 10bits mode

[nctnico]

High res means filtering. Look at the frequency of your signal.

Mine is a 4R but turned into 2354, not 2504.

[Elasia]

Mine just cleared customs with no duty charge.. woohoo

I'll do mine tomorrow and see what it does for upgrading with the serial

Yep, in this case bw is limited to 100Mhz when using the 10 bit mode.
