Many times, all you need to know is if a pin is high or low or toggling states, and takes less time to manually probe around a board than to hook up a logic analyzer.It's been a long time since I wrote a blog post. What might be more helpful for many people is a Logic Probe. The above quad-portable starts pushing up against the price of low-end bench scopes.įor less, you are back to USB-based scopes Other than USB scopes, this is a step between the bottom-end cheap boards and a bench scope. These are cool little boards that can plug into a breadboard. Other low-end scopes less than $100 might be enough for some people. I'm not saying that you should buy a DSO138, but instead that it might meet the needs of some people, and it's better than nothing. If a person is working with slower signals, then a low-end scope will be fine, but if a person needs to look at very fast signals then cheap scopes would be a waste of money.įor $254, this might be reasonable starter bench scope.Ī $17 DSO138 can show audio waveforms. It depends on what type of signals you want to examine, and what features that you can "live with" and "live without". You're not wasting money on a touch screen

Works like a USB drive so you can easily grab CSV data dumps without any extra software

UI design looks professional, almost like aviation software, there's no awkward Windows XP crapĬan handle mains voltage with 10x probe (I think! not that I need it) You can add extra apps (I guess for specialist automotive tasks) With wildcat's firmware it can do FFT, logic analysis/debugging (decoding and encoding some popular formats), advanced signal generation (including sweep with freq response profile) and what looks like a mode where you can do a line scan with amplitude as pixel colour! It's cheap, as low as £90 from some suppliers but realistically £150 if you don't want to wait weeksĢ analog + 2 digital channels (or 4 digital channels if you need)Īs far as I can tell this is basically a 18 or 20MHz bandwidth scope that can potentially go higher (maybe on digital, not confirmed), this is not ideal but I'm fairly confident it will meet my limited needs I could justify spending up to £200 on a nice bench top DSO, even second hand, but £200-400 feels like a step too far and I don't see any second hand Rigols for cheap.Īm I being unrealistic? Should I just live without it? Is there a decent digital bench top oscilloscope to be had for under £200?Įdit: thanks everyone, I've ordered a DSO203 (thanks /u/McShotCaller and /u/Enlightenment777) and I'll post a review if anyone is interested. What would you recommend? I would like to limit a USB oscilloscope to £50, maybe £75 if it had a combined logic analyser but I can just about live with my cheap Saleae clone. I definitely don't have space for a big old analog oscilloscope as much as I would love one. I'm not working with high voltage and I don't particularly need a high bandwidth oscilloscope, this will mostly be for debugging simple things connected to Arduinos. I get that and I am really on the fence because although I can afford it I really can't justify that much for a hobby and it may be that I only use it a couple of times a year - who knows. Looking around Reddit I get the impression that USB scopes are awful and I should invest £200-400 into a real oscilloscope like a Rigol DS1054Z or a second hand analog unit from ebay. I'm getting back into electronics and I need an oscilloscope.
