Technologies SDS1104X-E 100Mhz Digital Oscilloscope 4 Channels Standard Decoder, Grey

I think there are enough positives to recommend this scope over the 1054Z offering from Rigol to make the extra cost worth it. The user interface on this scope is responsive and clean vs sluggish response to input on the Rigols. The signal grid offers 14 divisions instead of 12. Menu headings do not overlay waveform view area. The sample rate at 4 channels is okay for a 100Mhz scope and mediocre for a 200Mhz scope. However, dual ADC's make it possible to get 2 channels at 1Gs/sec and that is pretty good. This is much better than the Rigol 1000Z series' single ADC that drops to 500Ms/sec at 2 channels and 250Ms/sec at 4 channels. The probes are decent but not anything special. Keep an eye on the 1X/10X switch which is easy to shift accidentally. Sometimes the hook catches on the hat instead of fully clamping on the lead so be careful to insure a good connection is actually made. The cables are slim and flexible which is nice. Unlike Rigol the remote access features of this scope are really useful. The built-in webserver updates quickly and allows you to view signals full screen on a PC at an update rate that actually makes using it worthwhile. A LAN connection is included and very simple to setup. I was able to use my laptop to control the scope in about 45 seconds of setup. The signal noise levels are pretty mild on the inputs letting me see some low voltage signals within reason. It is possible to add MSO capability later on, but the integration is not that good compared to the Rigol MSO1000Z scopes. Still it's an option that one simply can not add to a Rigol DS1054Z even with hacking. So far I am very pleased with this scope and would have no problem recommending it to hobby users or others that need a low cost 4 channel scope.

Probably the best value in oscilloscopes on the market. Comes with all the serial decodes unlocked (can't do some of the more uncommon ones, but the average hobbyist probably won't encounter them anyway). It's 500Msps with 4 channels on, so that's fine for the 100Mhz bandwidth (sin(x)/x interpolation wants the sample rate to be at least 5x the BW). The 1 Gsps is only achieved with 2 channels on (and they can't be 1 and 2 or 3 and 4, they have to be 1 of the left 2 channels and 1 of the right 2 channels). It's basically 2x the sample rate of the closest competitor, the Rigol DS1054Z, with no hacking to get the features most people want. Memory depth is great, even handily beats out the Keysight 3000x scopes at work. The UI is simple and modern. No complaints there. It feels just as nice as the Keysight scopes I use at work. Ethernet works well and is a nice feature at this price point. Many other scopes charge more for that feature than this scope costs. Wouldn't recommend the digital - the reports say since the circuitry for that is in an external box it can't do some of the things other MSO scopes can do. Not a detractor - I'd hardly expect any sort of digital channels in this price range. The optional WiFi (license key required) uses the TP-Link TL-WN725N. That's even Siglent's model number for it, so you can save a few dollars and buy it on Amazon. Minor nitpick - you can't use a USB mouse or keyboard to enter info, like you can on the SDS2000X Plus series. Since it's a Linux OS underneath, should be simple enough for the firmware to do that. Maybe a future firmware update. Overall great scope - feels like a professional level scope but at a price a hobbyist can afford.

Very nice scope has alot of features

Love it. Inexpensive for a whole lot of measurement and convenient features. Do look up website for details like FFT and decoding signals. FFT is extremely useful. Overall: It's a highly streamlined and optimised scope in an inexpensive package. Caution: If you want a Mixed Signal Oscilloscope (MSO) with a Built-in AWG, this model becomes less appealing with limitation of 1GSa/s. It's value is great as a basic scope but decreases as we add more options. Screen is beautiful with good contrast. Adjustable brightness and transparency (for background to display expanded waveform info). 4 Pay Options: 200MHz Bandwidth (if originally 100MHz), AWG, MSO and WiFi. AWG and MSO features require respective (optional) accessory components. The 3rd pay feature is for the WiFi, which also requires the TP-Link TL-WN725N USB WiFi dongle. WiFi is extremely useful for using a NTP Server (Google's NTP: 216.239.35.0) to sync time and date automatically. Without network connectivity, date-time stamp reverts back to 1970. No internal clock on battery. With a browser, by typing in the scope's IP address (to access its built-in webserver), we can access the scope and screen on the notebook, PC and Mobile device. Convenient! Firmware and OS are well maintained. No bugs or issues were detected so far on my part. The fan can feel a tad louder due to close working proximity. Limit at Max. 200MHz bandwidth, 1GSa/s per ADC. 2 channels share an ADC. Bode plot uses 2 channels from the same ADC. When both channels are being used it's 500MSa/s. If needs anything more, buy a higher spec. scope. Look out for promotions around Christmas, Black Friday, Cyber Monday and Amazon Prime Day.

Going from entry/mid level Tek scopes at work to this Siglent at home i'm more than pleased with the features. For the price, it really is hard to beat for hobby work. I have noticed the display save to png/jpg appears pretty fairly aliased but performing capture from the web interface is much more sharp. Serial and i2c decode work well, have yet to try SPI. Small signals trigger well and stable (audio and up to 75 mhz LO/IF freqs as low as 10 mV tested). I haven't gotten the logic probe or AWG options yet so can't comment on those. Good scope for cost.

This is my first scope. This is the most useful tool! I'm an electronics hobbyist coming from the computer science side of things. I've learned so much about my circuits using this scope, and it's helping me design them better. I first tried a $12 logic analyzer for a problem that I was having with some PWM signals, but I was getting garbage output. This scope helped me understand what was going on. It has been incredibly useful in other scenarios, too. I got this scope over the Rigol DS1054Z for these reasons: * I read reviews that the Siglent was a bit easier to navigate and the interface was more responsive. * I wanted serial decoding. * I didn't want to pay for extra licenses (or to deal with hacking it) to unlock higher frequencies or serial decoding. * The web server seemed useful. * The possibility to add MSO and waveform generator seemed useful to let me grow into new features. My afterthoughts on my original reasoning above: * I figured out the basics like scale, position, and triggers within 30 minutes of poking around. All other features like cursors and measurements just take a minute or two to figure out. Having never used a scope before, I'd say that it's easy to navigate, but I don't have anything to compare it to. * The serial decoding is nice to have (I've only tried I2C so far). It does feel a bit slow to respond for triggers, and when displaying decoded data of messages sent at 1Hz it only refreshes every few seconds. They may all be available in history, but I can't seem to get a real time updates to work. A $12 logic analyzer picks them all up perfectly fine, and that interface (PulseView) is easier to navigate. The best part about serial decoding on the scope is triggering on decoded events, e.g. I2C start/stop signals. Otherwise, I feel like the logic analyzer is better suited for decoding. * The web server is neat, but I prefer the physical buttons and knobs to control the scope. Having a larger display may be nice, but it's more convenient to just look at the scope's screen as you're adjusting the knobs (it's large enough). The web server could be invaluable for something like a video chat screen share or screen recording. * The MSO expansion costs nearly as much as the scope itself. Given my thoughts on the serial decoding, I don't think it's worth it. A $12 logic analyzer works well enough for low frequency signals, and a Digilent Digital Discovery can apparently go up to 800Ksa/sec, just shy of the 1Gsa/sec of this scope, plus it's only half the cost of the MSO expansion. * The waveform generator expansion costs nearly as much as a discrete waveform generator. I think I'd prefer to have a dedicated unit, if I ever need a waveform generator. For now my needs are met with some $3 PWM generators. In retrospect, I'm not sure if I would make the same decision to get the Siglent over the Rigol. Don't get me wrong - I love this thing! But maybe saving $150 on the Rigol would be more cost effective. You could use that money to get a decent digital logic analyzer. I'd say that the web server is probably the deciding factor. If you want to do screen shares/recordings then the Siglent wins, otherwise just get the Rigol. A potential killer feature that I think they missed out on is a screenshot tool built into the web server. Screenshot onto USB works fine, but doing this via the web server would bypass the USB storage device. Maybe Siglent could add this in a future firmware update?

Writing this review after almost one month of daily use. It was down to this or the Rigol DS1054Z. The Siglent is faster at 100 MHz (yes, there are easily found cracks to speed up the Rigol, but if everyone's using the crack, why don't they just sell it that way?). For me the deciding factor was CANbus & LIN decode, which works very well, and provides a good selection of CAN trigger options. Operation is a close follow of the Tek TDS scopes, so quite intuitive to use, and the LCD is bright and sharp. It comes with four reasonably high quality 100 MHz probes complete with spring hook 'witches cap', and snap-on color rings for channel ID. I used the ethernet port to plug this into my LAN, and the built-in web server provides a VNC-based realtime display. Since there's no touchscreen, they provide a fly-out button menu to allow remote control. You can use any VNC client for a display-only connection. Negatives: The Adjust / selection knob, which requires a push to click, is a bit twitchy, so sometimes pressing it to select an option bounces to the next item, and selects *that*. Requires a bit of care in use. The firmware gets updated about 2X per year, but there are separate downloads for the application updates and the operating system updates. Siglent doesn't bother to explain why you should, or should not, update the OS. The current version supports NTP to set the clock, but the options (sync on power on, sync at interval, clock display on/off) don't persist. Neither does the screensaver timeout. Channels 3 & 4 are color-coded light blue and light green, which makes distinguishing them a bit harder than it should be. Neutral: Scope allows save/recall of multiple setups (20!), but the menu defaults to *external* storage even when there's no USB stick plugged in. Comes with an IEC 3-prong straight plug which sticks out a good 2" or so from the back. The first thing I did was order a right-angle plug so I can place the scope flush against the back of my bench. Fan is somewhat loud, but low pitched, so no more annoying than my server when running. Scope has folding tilt-feet, but these are not sprung or latched, and it's very easy to pull the scope forward (say, while unplugging a probe), and have one or both feet fold up.

This piece of equipment is an absolute game-changer for anyone in the field of electronics or engineering. The functionality and features packed into this device are simply outstanding. From its crystal-clear display to its intuitive user interface, it's a breeze to use, even for someone like me who is relatively new to oscilloscopes. The accuracy and precision it offers are second to none, and I've been able to troubleshoot and diagnose electronic circuits with ease. Whether I'm working on a simple DIY project or tackling a complex engineering task, this oscilloscope has consistently delivered flawless results. The build quality is top-notch, and it feels robust and durable. It's clear that the manufacturers paid attention to every detail, ensuring that this oscilloscope will stand the test of time. I also appreciate the variety of connectivity options, allowing me to integrate it seamlessly into my workbench setup. Plus, the availability of software updates ensures that my oscilloscope will stay up-to-date and relevant for years to come. I also purchased a Wifi USB dongle so that I could connect it to my computer.
