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

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.

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.

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.

Powerful accurate excellent value real oscilloscope. Great value. Well made. Smooth controls. Neat features. A lot of oscilloscope in a small package and for a good price. Love it.

I used this scope for debugging some complex AC power issues and it was great. It's easy to use with many features, including a FFT for frequency analysis and using the AC power input as a trigger. It is well built and I would highly recommend it. The only thing to be aware of is that it's only an 8-bit scope so it doesn't have the dynamic range to look at very small signals right next to or within big ones. For most people the dynamic range will likely be more than fine though and this scope is perfect for many use cases.

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.

Siglent SDS1104X-E 100Mhz I've only had this scope one day but so far it is easy to use, no issues yet. I've only used it for some basic low speed monitoring of PWM signals in the 100 Hz to 5KHz range. I was wondering about screen size. The actual utilized screen size is about 177 mm. (154 mm wide by 87 mm height) I've mostly used TDS2024. It has the dedicated vertical position control for each channel that is missing here, but no big deal. I like the dedicated on/off channel buttons on the 1104. I've also used some of the nicer Rigols. There was something that never seemed quite right about the trigger on those, when looking for intermittent spikes. Seems like it often failed to trigger when it should (the TDS worked fine). I haven't done much testing with the trigger yet on the 1104, but it's working fine for these slow speed signals. I like the dedicated buttons for Auto, Normal, and Single Trigger. The fan is slightly louder than I remember with the TDS, but I'm in a super quiet room now. I don't think I would notice it in a normal office or lab environment. There is not any noticeable breeze from the fan, which is good. It's not like some power supplies I've had that sound like an airplane, and you can point it at your lab neighbor to really annoy them :). Probes seem adequate, although on one of the four of mine, the tip stays in the hat when I take the hat off.

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.
