![]() With all euphoria towards this scope there are some voices raising short comings and critics. Quote from: hj on November 02, 2021, 07:01:59 am Hi folks, 2104x+ owner here. (**) I experienced some predictable crashes in the past, for example when loading certain files. (*) A quick selection: Siglent SDG2042X: 22 seconds, Siglent SDG1032X: 23 seconds, Siglent SDM3045X: 17 seconds, Keithley DMM6500: 18 seconds. But would not be surprised if I end up buying an RTB again. If I’d need to buy an instrument in this range today, I’d surely look at all the options. Like any device, the RTB is not perfect and there are always things left to be desired – some of them reasonable desires given the price and category, others less so -). Although I only touched upon some (user) aspects in the above they make that if I go to my lab, the RTB is my instrument of choice that makes me happy when I use it. To me, some devices just feel ‘good’ when using them, others less so. Clever and clean layout, good looking, quality buttons, and rotary dials (much more pleasant than my Keysight DSOX and many more instruments I have). Even if this device has been on the market for some years, R&S have been constantly addressing things and also has been issuing meaningful additions even recently (like a variable low pass filter in its mathematics section). ![]() It’s great for screen video capture (for future reference or sharing with others). The ‘life’ UI via the webserver is 100% identical to the front panel (buttons and screen) has no delays on controls or screen update whatsoever. No cryptic messages, no functions that depend on some other setting hidden in a different menu, etc. Items are exactly in the places /menus where you expect to find them, from day 1. No Christmas tree of presentation modes, fonts, entry methods, etc. It’s well thought and consistently implemented. Snappy and consistent, regardless of the mode or menu you’re in. (*) - A very fast and responsive user interface. Most other instruments on my bench also take at least twice as long to power up. This is heaven compared to my Keysight DSOX1204G oscilloscope which takes a frustrating 45 seconds to start up. It takes a mere 10 seconds before you can do your measurements. I was surprised to see several critical comments about this perhaps there have been significant firmware upgrades in this regard before my purchase 1.5 years ago? Using the current firmware version (2.30) I see: - a really fast power-on. Let me in the below comment a couple of reasons why. In fact, I consider myself to be a rather satisfied user the RTB is probably my preferred kit on my bench. But as an RTB2004 user, I’d like to share my experiences with that instrument. I do not own an SDS2104X+, so will not comment on that. Remember he is reporting this for the 1102x but I can reproduce it on the 2104x+ and already asked if this is DSO standard behaviour or Siglent specific in the main thread (maybe some of you experts can answer this question for me:) There are other things this guy complains especially the massive oversampling on decoding signals reducing the effective recording time down to 0.28secs (for the 14MS buffer) BTW: He ended up getting a RTB2002 YMMV, Jo some other stuff This one is about the effective DAC resolution available on screen. ![]() ![]() As I have already stated, I am a DSO new-by with no first tier DSO experience so I can't really judge and assess it but here are two german YT videos that reveal some stuff: This guy compares the 2204x+ to his LeCroy well aware that the two devices are in a different league to show - wave form going wild beyond a certain vertical threshold (~10:20) - over/undershooting square wave edges due to over compensation of the analog inputs (~11:40) He puts it into perspective "if you know that the scope does this, you can live with it at this price point". ![]()
