I have lasted with my 2 channel 20MHz USB scope since 2007, and it has done me well. I got the PropScope after I did the technical review for it at Parallax. For a USB scope it does a whole gambit of functions. Like I mentioned, it’s a 2 channel, 20MHz bandwidth, 20Vpp (this is what killed me on bigger projects and did for many customers that I talked to), came with a function generator and Logic Analyzer, though you can only use some of these in limitation together. I am working on fine tuning an AC Controller board, and needed to view 120VAC, and there was just no way the PropScope could do it. So, it was time for an upgrade.
Turns out the 4-channel scope industry has been largely uncontested by Rigol. Recently Siglent looked to change that. Hantek seems to have thrown their hat in as well. Siglent has plenty of other scopes that run thousands of dollars, but my budget just didn’t allow me to go that far, and if I did, I would have gone the Tektronix route. My budget had to stay under $500.
Enters the Siglent SDS1104X-E at $495. After many hours of reading about scopes, researching differences, and talking with another long-time developer (Chris Savage), we both got this scope for our personal use. It’s a 4 channel (WOO HOO), 100MHz, 1GSa/s duel/ 500MSa/s quad scope with plenty of perks. It has serial decoding for UART, SPI, I2C, CAN, LIN (automotive and robotic arms use this communication), printing to thumb drive or data saving, 400Vpp (I clarified with one of the Siglent engineers), and it doesn’t require me to plug it into my PC though I can run it over LAN if I wanted to and many more features.
I talked to Siglent directly and worked with a few people within the company to see how their customer service response time and communication operated like. I have been very happy with the results and pulled the trigger and ordered with them. They matched a price and comped shipping and I have been in communication with their support, engineering, and sales team frequently. So far, so good, and with the completion of my desk build it has a permanent spot in my workspace, I can really put it through the paces.
