FNIRSI 1014D - How to use the signal generator

[@ChupoCro]

I found this oscilloscope very intuitive and easy to use even without reading the manual. But everything you showed in the video and much more is clearly explaned in both the manual I got with the device and in the manual downloaded from the manufacturer's site.

[@curtvincent3355]

Ah! Finally! You figured it out! So easy once you explained it but without directions it was maddening! Sincere thanks!

[@ecosta]

Thanks! I’m glad I could help!

[@danedewaard8215]

I like your humor!!! This scope was like a jigsaw puzzle! The fun was figuring out how to use it and for that they gave a discounted price!

[@werner7156]

Hmmm.. I haven't thought of that yet, but that's an option if I don't really like it, I'll definitely check it out as soon as I get it delivered. I don't really need 100 Mhz, but if it's sold below, someone has to stand for it

[@pavolkrupa4036]

thank you very much. you are good teacher. you help us

[@spasovski1984]

can you adjust the amplitude of the signal, for example i would like to gave 0.775 v (0 db)?

[@andersjansson6705]

Yes, good that you showed how to create custom generator waves. Thx

[@eduardoo1652]

very good, very useful function, thank you very much

[@hacklabdesign]

How can I check to the frequency of what a tens unit produces.

[@TitoSpadini]

Thank you for this video. Please, do you know if it is possible to specify the amplitude of the generated wave? It seems to be a fixed value. Apparently, it allows to change the frequency, the wave type and the duty cycle, but not the V.

[@ecosta]

As far as I know, you can't. That's quite a limitation, unfortunately.

[@TitoSpadini]

@@ecosta thanks for you reply.

[@werner7156]

just modify it yourself or use an amplifier. the amplifier could also be installed internally as there is more space in the housing than is necessary. I will install a 3S battery pack with 5 A in the housing and connect a step-down converter because the power supplies obviously produce interference.

[@RJHElias]

Thanks for the explanation, can you also make a video about how to set time/div? I have issues with that

[@ojbeez5260]

How do you get it to generate the signal in the first place?!?!? No explanation of how to generate the signal using the signal generator??!!

[@HowardJohnstone]

Is it possible to record a frequency sweep (other gen) and use as a custom file for audio Frequency measurement?

[@almircampos]

How about the voltage amplitude? Can we change it?

[@SongsForDamnation]

Thanks for the video. Is there a way to set the amplitude of the standard waveforms of the signal generator? I have the same model and I really can't figure out how

[@ecosta]

As far as I know, you can’t do that. It outputs a signal between -1 and 1V, then you transform it as needed. For digital signals, I was able to use a transistor. Analog might be doable with OpAmps, but that’s a domain I’m not knowledgeable.

[@PeterMLauer]

I got the unit too, looks like it can't adjust the output voltage of the generator, its fixed to about +/- 1.5V on sinus output

[@don7680]

I believe you can calibrate the probes using a 1K square wave from the generator?

[@ecosta]

It is possible. I’m not good at it, but I was able to use the generator to calibrate the probe.

[@antoniobregoli9305]

Hello . Sa dove service fnirsi? Best regards

[@paymonsani]

I found it useful, thank you for sharing. How do I adjust the gain of the signal in the signal generator? I need to produce a 1KHz sineware signal (this part is easy now) but how do I adjust the Vpeak for this sivewave signal?

[@werner7156]

I think it's a pity that this oscilloscope comes off so badly with all the KZbin videos, most of the people who do a test here are professionals who simply assume a different standard that takes place in the upper price range... the corresponding ones are then too results. I ordered the scope anyway, it's more than enough for my applications, but I'll get it in 14 days at the earliest. Apart from whether the specified data is correct or not (which will still be proven) the only thing that bothers me about the Oszi is that there are no indicators for the push buttons (LEDs) and the weight also seems to be too light to press buttons without it slipping on the table, so I'll will add some weight in the Housing. I will definitely install a signal amplifier in the device because it is absurd that the amplitude cannot be changed. Otherwise, I can only assume that the current price for a two-channel scope including a function generator and other functions is just great. What is or would be of interest to me personally... It is often criticized that this is not a real 100 Mhz Oszi, maybe someone can try and measure a single cell pulse in a pulse series at 100 Mhz with a courser, which would give results stress me out. A big problem seems to be the power supply, which generates spikes, but for my own safety I will only use battery power anyway. When my Oszi is there I might make a video because there is nothing to be found in German. I only bought the part because my old tube Russian analogue Oszi ( 50 years old ) smoked away I can't get any original parts for it :-(.... between the stand of the Russian Oszi and the FNIRSI 1014D there are galaxies !

[@alb8758]

I feel like I'm missing something fundamental, how do you change the amplitude of the signal generator when using the non custom signals? EDIT: oh, just saw the other comments, I guess you can't. Ok I can work with the default amplitude for my purposes anyway.

[@bobisyouruncle1]

You cannot. It's fixed at 2.5vpp

[@StarJar58]

Very helpful. You talk like me! And your fingers and nails look like mine...oops off subject. Thanks for showing what you figured out. It would have took me days. I like my machines though.

[@halalexpressions]

Hi, you said, you will record the basics of using an Oscilloscope. I am new to electronics and I just bought this one. It would be awesome if you could spare some time and guide newbies on how to use it with basics. Thanks in advance.

[@ecosta]

I'm glad to see some interest in this topic! I'll find some time to do something more basic.

[@halalexpressions]

@@ecosta Thanks

[@houasidou]

there is a possibility of making a video with a circuit of three resistors powered by the oscilloscope generator, measuring the voltages of each resistor and visualizing two voltages of two different resistors, thank you for your precious time

[@RodolfoGuimarãesdaSilva]

Can you generate am modulated signal with FNIRSI 1014D generator?

[@rtwodtwo9338]

Nice demonstration ! I have the same model but the first channel is almost blind ! And the second is not accurate . My psu output is +5V and the oscilloscope measures +4.3V dc. Overall is a nice scope but the measurement accuracy is a very significant thing. I am not sure if there is anything I could do to fix the problems..

[@werner7156]

YOU should maybe look under the blister covers to see if the chips are soldered in correctly, with the model it is very common that they are positioned incorrectly. there are some videos on youtube of the procedure kzbin.info/www/bejne/hoSQdnRuidGfa5I

[@rtwodtwo9338]

@@werner7156 Thank you for your answer , when I find some time I will proceed with the operation!

[@werner7156]

@@rtwodtwo9338 No problem. please leave feedback here if this was your problem for others ! BTW.. after the repair, be sure to calibrate again in the menu.

[@miss.wright3035]

Can this replace my old millivolt meter ? Can it read .3 mV / 250 kHz ? Can it generate .2 mV 500 kHz Sine ?

[@ecosta]

I think it might be able to do both, but it is not really easy to use as a signal generator. If you need/want a cheap oscilloscope (and you are willing to accept its limitations), then it is a good product. But if you only want to replace something that currently works, then I would not recommend this change.

[@fickfehler3866]

@@ecosta Your response didn't answer the question. Sounds like you don't even own one ?

[@ecosta]

@@fickfehler3866I own the one used in this video. But I'm no expert to give a solid answer those out of blue - I would need to test these with a real circuit. All I can give right now is my opinion.

[@3dsmaxrocks699]

New to scopes.....so go easy on me. Does this scope show the waveform in dot mode AS WELL? Like a single dot going across the screen instead of a line? I know it can do all sorts of divisions of the waveform.....just curious if it can be set to see a single dot

[@ecosta]

I'm no expert as well, but this model doesn't have a dot mode - as far as I know.

[@alejandrocollantes]

Hi! I appreciate the video and the good intentions, but I believe the first thing to make a good video is to have a plan to explain the different topics and speak clearly and slowly, trying to have a clear and paused pronunciation to reach everybody. Thanks for sharing, but, please, try to observe these basic rules.

[@naasikhendricks1501]

I had one... it really noisy at 10ns/div and 50mv/div. It can be resolved, by powering with linear regulator 5v 2a or battery. I got 150 to 200mv made it difficult to use for anything useful. The second channel was really difficult to calibrate.

[@ecosta]

Thanks for the info! I noticed some of those issues and I'm glad I'm not the only one. I'm waiting for a new power bank to try it on batteries, but I might look for a decent power supply as well.

[@naasikhendricks1501]

@@ecosta I would advise trying to get a linear power supply if you want constant results. The power bank will only help for a bit. Alternatively break open the power supply and soldier on power supply pcb output point xr7 caps 2x22uf , 10uf , 4.7 uf and 1pf. The frequency that is generated from the power brick is between 45 to 140hz depending on your mains. Those caps will do the trick if you a diy person.

[@ecosta]

@@naasikhendricks1501 got it! It’s a matter of waiting for a bunch of deliveries. I will try your idea later!

[@naasikhendricks1501]

@@ecosta no issues. It will help reduce that noise to about 10mv. You can even create a small perf board with caps. You can add a common mode choke. Plus with the perf you can decap like crazy, if your local noise is different. I discovered that fnirsi power bricks are very inconsistent they will have you scratching your head when looking for a part of the noise. If you want to check a op amp, 10mv, it's crazy high noise. All the best

[@robertoperotti6644]

hi, can the fnirsi 1014d generate an amplitude modulate sine wave ?

[@ecosta]

Not on its own. Its wave generation capabilities are very limited

[@hardykefes5686]

Thank you for the video. Very helpful, yet very hard to listen as you keep jumping around and not finish a thought before you add information. A more structured presentation would very much improve your video. Still very helpful.

[@gianlucamazzoni1672]

It's possible use for laser cd eye pattern reading??

[@ecosta]

Well, an oscilloscope translates voltage over time into a visual graph and detects when a specific threshold is crossed. Assuming you are not actually pointing Class I lasers into people’s eyes (which will blind them before you get a working prototype), then all you need is a circuit to translate whatever your output is to a voltage signal. Then the opposite to translate it back to your input. Also, assuming again you are not burning people’s retinas, this device is not super precise nor fast. You will struggle if you need higher frequencies - which I imagine is the case for last signals

[@kv4atv]

@@ecosta Have you tried to or looked into taking a sample at the LASER emitters input and the receivers signals? You should be able to see the sent signal on one channel and the reflected signal on the other channel. Won't hurt to try and see the results. Do know that the frequency of LASER pulse can be Way beyond what these scopes can capture. I work with LASER communications and some of them are in the 680,000 GHz area. That speed allows LASER to send and receive 1-2 TBs speeds.
