content: 2 models it seems ....The SMM3000X series is a precise source/measure unit (SMU) instrument that can simultaneously source and measure voltage and current. It integrates current source, voltage source, voltmeter, and ammeter functions, and is particularly suitable for semiconductor feature analysis, nanoscale devices and materials, organic semiconductors and other test applications.Key Features6½ display digits (2,100,000 count)100,000 points/s maximum acquisition rate10fA / 100nV minimum programming and measurement resolution±210V / ±3A(DC) /±10.5A(pulsed) Maximum outputSupports DC, pulse, scan and list output, minimum pulse width 50μs5-inch touch screen with graphical and numerical viewsFeatures and BenefitsWebserver5-inch true color TFT-LCD large screen display, resolution 800*480,with touch screen and new UI interaction, graphic and digital view mode10 fA / 100 nV minimum output and measurement resolution6½ display resolution (2,100,000 count)Maximum sampling rate 100ksps, 0.0005 PLC sampling interval, maximum100 PLCMinimum trigger interval 10 μsUp to 100k points of internal storage space, support time stampFour-quadrant precision power output (single/dual channel) and measurementUp to ±210 V DC voltage, ±3 A DC current/±10.5 A pulseFive basic modes: voltage source, current source, voltmeter, ammeter or resistance meterSupport DC, pulse, sweep and list outputThe minimum pulse width of pulse output can reach 50 μsArbitrary waveform generation and list sweep function (minimum 10 μs interval)Two-wire measurement/four-wire measurement, Delta low resistance test method,Effectively compensate for measurement errors caused by thermal electromotive forceSupport standard SCPI remote control commandsOutput filter time constant can be set to achieve different frequency response outputs, maximum5msConfiguration interface: USB Device (optional USB-GPIB adapter),USB Host, LANDatasheet (Chinese)https://www.siglent.com/wp-content/uploads/2025/02/SMM3000X_Datasheet_CN01A_.pdfMore info to follow as it becomes available.Unknown western release date....

content: Quote from: 2N3055 on February 28, 2025, 05:19:07 pmThis is interesting, mentioned to Rob a few years ago Siglent should consider a SMUDual SMU will likely be north of $6K.Wonder how it will compare to the GW Instek??Best

content: Quote from: mawyatt on March 01, 2025, 12:55:27 amYes we spoke about it how it would be nice. Apparently Siglent listens...I think it is too early to say anything about anything. Nobody saw it yet, and there might even be market differentiations if/when it comes to the west.There is only datasheet in Chinese and that one is V. 1.0.0.0.It is part of "serious instruments" line and price will be in line with that. I doubt it will be hobby purchase..Everything else is too early to even speculate...

content: Quote from: 2N3055 on March 01, 2025, 10:38:39 amWell, since it is 3000X (and not A) it will cost less than a middle class carSpec-wise it does look very ambitious in my book. Will there finally be an alternative to Keithley?

content: Quote from: Performa01 on September 08, 2025, 08:03:03 amThere is no direct match to Keithley models AFAIK.It has more power than 2450, lot more pulse current too.It also have 2 ch (very compact) version.It also have 100kSps/s sample rateIt actually covers range such that you would need to buy two different SMU from Keithley to cover.Yes, ambitious sounds about right...

content: It would be nice if they could add some waveforms for the output voltage or current source generation, like sin waves and harmonics. I hope they shock the market with a price of under 800$

content: GW Instek has a SMU competitive with Keithley, the GSM-20H10. We almost got one for a previous project (new chip design and test that didn't progress past the conceptual circuit design) when Newark had a "Special Sale" for about ~$4K. Before we could even think about it, these were gone!!Will be interesting to see how this new Siglent SMU behavesBest

content: In performance specs, it's clearly gunning for the Keithley 2600 rather than the 2450 -- and while it only modestly excels on that front, it really pulls ahead in areas of technological innovation such as not using a vacuum fluorescence display on a new $10k instrument in 2025.

content: The 2600 is a cludge to use from the front panel. I honestly don't understand why they even bothered with a front panel, it's really a system meter for remote use, and too noisy for the bench. Even a single channel instrument on the bench is best used from PC software. To make the most of an smu you want arrays of data, some math processing and graphs (not on a 5" display thanks). Unless your just using it as a fancy psu with high res current reading.

content: These appear to be a copy of the Keysight B2960C Series SMUs. Will be very interesting to see the prices - in the UK a single channel B2961C goes for £8665 and a dual channel B2962C for £12537.

content: Quote from: chilternview on September 09, 2025, 07:35:26 amYou mean designed to compete in same specifications bracket?Specifications wise they are very similar to B2961C/B2962C, I agree.Output connectors are also in a same configuration,AFAICS their user interface has no resemblance....If anything, in that regard they take design clues from Keithley touch screen SMUs, but it also looks completely different when you use it...So I would agree that it could be compared somehow directly with B2961B/B2962B

content: Quote from: MadTux on September 12, 2025, 09:58:59 amYou're right that nylon is NOT ideal, but nice thing about the safety plugs is the long path from mounting point to terminal. I've had no issues using them as a breakout for a K236(7) SMU, though I did put a guard ring around them by using a PCB as a front panel (hidden by the lip of the connector - can't have it exposed due to the voltage present), see here for some pics:https://www.eevblog.com/forum/testgear/test-equipment-anonymous-(tea)-group-therapy-thread/msg5541853/?topicseen#msg5541853
