				Hi,
 
 I've been troubleshooting a serial port issue, & fired up the old 
 Telequipment scope for the 1st time in about a decade. Spent more time 
 bringing it out of hibernation than actually using it, and it occurred 
 to me that at today's prices, an el-cheapo solid state scope might make 
 sense to have next to the digital meters (or maybe, in place of...).
 
 Anyone here tried any of the sub-$100 models, or even the sub-$50 
 versions? Obviously not looking for lab grade here, just something 
 mainly to detect signal presence/absence.
 
 Thanks,
 
 Charlie

				I have use the pokit meter from   https://pokitmeter.com/ Multimeter, single channel scope and data logger, uses your phone as a display.

				Charlie,
 When I was debugging a serial port issue, my son borrowed a logic analyzer from his office and we connected it via USB to his laptop. When clipped to the TX and RX pins, it was able to decode and display the ASCII characters being transmitted. Much more useful than a simple oscilloscope would have been. See if you can find one of these logic analyzers that hooks up to a laptop.

				If you truly just want to see the presence or absence of a signal, one of the cheap 1-channel Chinese scopes work pretty well.  I have one of these...
 
 http://www.ebay.com/itm/163807642144
 
 ...and it's surprisingly decent for basic troubleshooting away from your bench.  It's low-bandwidth and probably isn't very accurate, but it works to see if there's activity or not.
 
 If you want to decode a serial bus to see what's happening, this is a decent option at low cost:
 
 http://www.ebay.com/itm/123355594893
 
 Or, if you want even cheaper, there's this option:
 
 http://www.ebay.com/itm/383085783631

 P.S.  All three links are to the lowest cost U.S. seller.  All are available cheaper from China if you want to wait a few weeks.

				Hmmm... good thought. I might consider       two instruments, instead of just one. A scope would have a wider       application, though. 
        
        Thanks for the idea.

				Hmmm....I was more focused on a self       contained instrument, but that path might actually be a better       idea. I'll did through the site to evaluate.
        
        Thanks!

				That's the Rolls Royce option. Does it       make sense to hunt for a logic analyzer when it will likely be       sitting idle for the next decade? A simple multimeter with scope       option is a lot cheaper and will get more use.

 A very capable hangar neighbor of mine showed me this unit that connects to a PC.
 https://www.picotech.com/products/oscilloscope
 
 The base level unit (~$80) is quite capable and can log the the waveform and continuously convert the waveform to ASCII characters.  I think this is similar (or the same) as what Art Z. described.
 
 The manufacturer offers some very high end scopes and claims to extend their quality and performance through their entire line.
 I’ve not purchased one (yet) as my legacy big box scopes are still working but for convenience and added functionality I’m looking forward for an excuse to purchasing one.

				In general, I'd agree, but a toe in the web waters found that not everything has been tariffed out of existence (yet). The 1st example I found:
 https://smile.amazon.com/HiLetgo-Analyzer-Ferrite-Channel-Arduino/dp/B077LSG5P2/ref=sr_1_2_sspa?crid=1A07VX9T9OILX&keywords=logic+analyzer&qid=1580995620&sprefix=ogic+anal%2Caps%2C206&sr=8-2-spons&psc=1&spLa=ZW5jcnlwdGVkUXVhbGlmaWVyPUEyTzVFVUlIUVlGWlIyJmVuY3J5cHRlZElkPUEwNTI2NzYyMjEzSU9FVFVPUjBLVCZlbmNyeXB0ZWRBZElkPUEwOTc0MDg3M1E5VzlKVUk4RlBZTiZ3aWRnZXROYW1lPXNwX2F0ZiZhY3Rpb249Y2xpY2tSZWRpcmVjdCZkb05vdExvZ0NsaWNrPXRydWU=
 
 That would be less expensive than a new set of voltmeter probes.   And it seems to have the somewhat weird sounding advantage of *not* having batteries, since I've managed to damage several rarely used instruments by forgetting about the installed batteries.

              When               I was debugging a serial port issue, my son borrowed a               logic analyzer from his office and we connected it via USB               to his laptop. When clipped to the TX and RX pins, it was               able to decode and display the ASCII characters being               transmitted. Much more useful than a simple               oscilloscope would have been. See if you can find one of               these logic analyzers that hooks up to a laptop.

                Hi,
                
                I've been troubleshooting a serial port issue, & fired               up the old 
                Telequipment scope for the 1st time in about a decade.               Spent more time 
                bringing it out of hibernation than actually using it, and               it occurred 
                to me that at today's prices, an el-cheapo solid state               scope might make 
                sense to have next to the digital meters (or maybe, in               place of...).
                
                Anyone here tried any of the sub-$100 models, or even the               sub-$50 
                versions? Obviously not looking for lab grade here, just               something 
                mainly to detect signal presence/absence. |

				Hi Dan,
 Thanks for the link. That does look interesting, but until I get around to setting up an actual electronics bench again, my desire is for something I can easily take to the work area, like a hand-held VOM. I do have the Telequipment and also a 10 NHz Tectronics analog scope for bench work, but balancing one of them on the wing of the a/c for troubleshooting isn't fun.

				Be careful though. This appears to be       an Arduino with some software. Cute but not up to the task for       real RS-232. The inputs are standard TTL and will fry if you       attach RS-232 level signals to it. You'd have to add a level       shifter (MAX232 or something like it), or a limiter of some sorts.

                          I've been troubleshooting a serial port issue,                         & fired up the old 
                          Telequipment scope for the 1st time in about a                         decade. Spent more time 
                          bringing it out of hibernation than actually                         using it, and it occurred 
                          to me that at today's prices, an el-cheapo solid                         state scope might make 
                          sense to have next to the digital meters (or                         maybe, in place of...).
                          
                          Anyone here tried any of the sub-$100 models, or                         even the sub-$50 
                          versions? Obviously not looking for lab grade                         here, just something

				Good point, but I just linked that item       to show how stupid cheap decent test gear is getting. The 30V 10A       fully adjustable voltage *and* current limiting supply I bought       recently for ~$60 would have cost me at least $300 30 years ago,       *in 1990 dollars*. It's almost like they're paying you to take the       stuff.

The inputs are standard TTL and will fry if you         attach RS-232 level signals to it. You'd have to add a level         shifter (MAX232 or something like it), or a limiter of some         sorts.

              https://smile.amazon.com/HiLetgo-Analyzer-Ferrite-Channel-Arduino/dp/B077LSG5P2/ref=sr_1_2_sspa?crid=1A07VX9T9OILX&keywords=logic+analyzer&qid=1580995620&sprefix=ogic+anal%2Caps%2C206&sr=8-2-spons&psc=1&spLa=ZW5jcnlwdGVkUXVhbGlmaWVyPUEyTzVFVUlIUVlGWlIyJmVuY3J5cHRlZElkPUEwNTI2NzYyMjEzSU9FVFVPUjBLVCZlbmNyeXB0ZWRBZElkPUEwOTc0MDg3M1E5VzlKVUk4RlBZTiZ3aWRnZXROYW1lPXNwX2F0ZiZhY3Rpb249Y2xpY2tSZWRpcmVjdCZkb05vdExvZ0NsaWNrPXRydWU=
              
              That               would be less expensive than a new set of voltmeter               probes.   And it seems to have the somewhat weird               sounding advantage of *not* having batteries, since I've               managed to damage several rarely used instruments by               forgetting about the installed batteries.

Does it make sense                   to hunt for a logic analyzer when it will likely be                   sitting idle for the next decade? A simple multimeter                   with scope option is a lot cheaper and will get more                   use.

                   	  | Quote: | 	 		                     Hmmm... good thought. I might consider two                     instruments, instead of just one. A scope would have                     a wider application, though. 
                      
                      Thanks for the idea.

                          When                           I was debugging a serial port issue, my son                           borrowed a logic analyzer from his office and                           we connected it via USB to his laptop. When                           clipped to the TX and RX pins, it was able to                           decode and display the ASCII characters being                           transmitted. Much more useful than a simple                           oscilloscope would have been. See if you can                           find one of these logic analyzers that hooks                           up to a laptop.
