The oscilloscope probe it came with the unit looks really familiar, It’s the same probe I got with the handheld scope I bought last year, most likely all these manufacturers of handheld oscilloscopes are buying the same off the shelf probes.
When I was looking for my first scope a few year ago I chose to get a big old used Kenwood CRT 2 channel instead of a little modern portable one. I don't regret it. It's a joy to use. That said, the functionality from these little devices is incredible.
@@12voltvids It was worth getting just to meet the seller... an old Georgian (the country) gentleman living in Ireland, he maintains analogue radio gear for the army. The o'scope was from a local college and had service tags. It came with a late 70's 'Feedback' analogue signal generator. That needed a new power supply. They are both solid workhorses. Can't beat old gear.
@12voltvids Nice tear down and demo. My DSO firmware version is 1.5. FW 1.6 is now available in FNIRSI web site. The manual says you have to keep pressing the power button while the firmware is updating. Have you done a FW update ?
I have one on order, just to try it. My biggest concern is the probable longevity of the connector. An inadvertent stress might damage the PC board. Sadly I don't have the space for an analogue scope so my Rigol will have to do as my main scope.
Great little device. With firmware version 1.6 they made it impossible in the generator menu to enter frequencies above 10 kHz. I don't know if it's just so the product doesn't compete with their more expensive lineup or if there was some risk of instability with higher frequencies.
Likely so it doesn't undermine more expensive models. Usrobotics was king at that. They had a very expensive modem back in the day. The usr dual standard. For those old enough to remember. There were 2 high speed standards. HST and .v32 then v.34. In the bbs days some sysop chose HST and others v.3x. You needed the correct modem or you were limited to 2400bps. HST went to 33.6k v.32 28.8k. The dual standard did both and cost a fortune. About 1000.00 USR also had the sportster modem which was v.34 version which sold for 149.95 and was the exact same modem as the dual standard. They just disabled in firmware the HST protocol. Thing is you could enter an AT command in the initialize string to re-enable it. That news spread like a wild fire and everybody was buying these cheaper models and sending the command. So usr struck back and encouraged an update for security. Ya, their financial security. Many got sucked in to the upgrade only to find the AT command now returned an error and they had down graded the modem. A few guys set up shop to refresh the old version back on for a cost. Same goes for one of my hdmi capture devices. It ignores the hdcp protection but all the cirrent ones will not record hdcp content and 100% guaranteed if I put the update on mine that the manufacturer has encouraged me to to improve performance it will down grade it.
My V1.5 generates clean signals upto 22Khz. FNIRSI has introduced random frequency error above 10khz so that the displayed reading is not correct. The device can be used with external measuring device. I feel it is capable of generating 100khz with a hack.
If I understand correctly the bnc from the signal generator goes to the oscilloscope and what is that small cable called and what does it go to ? Also can you shut off the tone while generating a signal ?
The way I pronounce it (which could be incorrect) is "nurzey" keeping the "F" silent. Makes more sense in English, as this is obviously a Chinese brand. The bandwidth is good up to 1MHz.
Most of the names aren't meant to be pronounced as a word. serpentza did a really good video about why stuff like this gets the odd names they do; it's tied in with the shipping subsidies or something
That is the target market period someone just working on older audio gear. That's what it was basically designed for that you're not troubleshooting an LCD or plasma TV with one of these or anything that uses really high-speed data.
As an audio oscilloscope I'd greatly favor a USB audio stick with a SW scope. This is waaay too slow. I mean: perhaps you could set a level on it... not sure how accurately, but phase shift? transients? with that kind of refresh rate I am not even sure you could tell if a photo detector going high and low is working.
man thats crazy, i used to daily the old DSO138 almost 10 years ago. Then i tried to get the then new DSO150 but i got a counterfeit one confirmed by JYETech themselves lol. I Started to fall out of the electronics hobby about 5 years ago now :( that 153 looks worlds ahead of my trusty 138. I Think the 138 was only rated for 100kHz tho. 150 was i THINK 150kHz. both were driven by an STM32 of some kind. I Would have loved that built in function gen. i just built a kit with the old XR2206
My very first DIY project was a scope (passed through adjusted signal to computer software via audio input) and function generator with a tiny single ended amp. No money for gear at the time and it helped fix a few amps;)
Good Oscilloscopes are not cheap, and having invested in a good analog one many years ago i still prefer it. These modern LCD digital ones have too many limitations, so expecting a small pocket size one to perform well is asking a lot. Probably ok for simple waveforms, but not realy suited to working on video gear.
The tektronics on my bench was free. I have 2 others that also cost my nothing. They are only expensive if you look on ebay. Lots listed on other sites for cheap
@@12voltvids The one i bought was fron the A/V shop that i worked for and closed. They bought it with all the test rigs and discs for Pioneer, Denon and Sony CD.DVD and Laserdisc players. it was not cheap when new, but still outperforms the LCD DSO ones that are as you say are not great for video /RF waveforms. All my other test gear came from surplus suppliers and auctions, all i have bought recently were some bench power supplies and an autoranging DMM.. Buying gear on ebay is not worth the risk, most of it is faulty and expensive.
It is what it is. It's cheap. For looking at basic data circuits and audio its fine. Its like 30 bucks what do you expect. For many this is all they require. If you need higher performance then you will pay hundreds or thousands. The thing is most obvious don't need that kind of performance they're looking for audio signals or clock signals or data lines. To tell you the truth the 63-year-old HP dual trace 10 MHz analog scope that I have sitting on the floor under my bench is more than adequate for 90% of the stuff that I would need a scope for. Even my $500 digital scope that I bought thinking it would be a great bench scope to have is useless for what I needed for which is looking at analog video and iPad and's off of CD and DVD players. In fact in addition to my analog scope this little one would be a perfect addition for doing things like tape speed calibration and generating test signals. That's more than likely what it's going to be used for. Generating test tones.
I have the same experience. My 152s are great, but I needed the vertical trigger to be adjustable beyond 4div. I got the 153 as the trigger goes through all 8 div and it has the horizontal trigger. I was all excited to retrofit into my project, but after some testing, I'm really disappointed. Screen refresh rate is horrible.
WOW. At almost 64. I can still hear that high. HAHAHAHAHAH My Logitech Sound system reproduced the Highs really well... I remember a Trip to the Dayton Hamvention. The Bus had CRT Video monitors hanging from above. and with no Video the Horiz outputs went buzzerk and it was so loud. there were a few on the bus that could not hear what I could Hear. I had to ask the Bus Driver to turn off the Monitors when the Movie was done LOL... Thanks Dave...
I noticed some distortion at the extreme high and extreme low frequencies if the amplitude was turned to maximum output. If I set the output to < 3 V it seemed to be fine but it was just when it was turned to the maximum that I got weird things in reality though most audio generators are not outputting 3 V you're outputting typically 1 or 1 and a half so this was kind of the acid test of seeing how it output at maximum and gain it did okay. The rated speck on it was only to 10 kHz but as we saw it went to 22 before it crashed out. For the money however it looks great.
I wouldn't know because I have never seen one before. Same with the tiny ones used to connect wifi cards to the antenna. Couldn't tell you what they are because I have never looked them up. That should tell you how much I care about this shit. I guess if I had to order one I would look it up but as far as plugging something in I don't care. I know sma (threaded) bnc, tnc, pl259, N, F ect but all the others nope. Don't care. Lol.
Back when I went to high school, the scopes were big. And had round screens. I never dreamed of it coming in pocket size!
Not much in them these days.

Yep, I got 2 of these years ago for my analogue scope. They work flawlessly. I only use for audio frequencies though.
