Thank you. Great tear down. My supply is dead (lightning transient with rear switch ON). Thanks to you I have a plan. First, apply +/-12V & 5v to main board and check for operation. If it is still good, rather than fix the power supply, I would like to supply the needed voltages thru a connector on the back. That is because people have commented that the switching supply in the box contributes to noise on the waveforms. BTW, with the rear switch ON, any power failure and restore turned on the generator.
yes, i have mine on a switchable outlet i dont want to let it run 24/7 get rid of the awful psu and put something good low noise in there. like those small mains psu modules that output +-15v with 7812/7912 afterwards and one for 5v
look for RAC20-K and LH05-23B05R2 on digikey, they should do. or RAC10-15DK if you want to add linear regulators for +-12v afterwards to lower the noise even further. @@dougbas3980
Im not able to adjust the duty cycle for rise and fall in square 4:19.. seems like there is a bug on Fy6900 sw 1.3.1 and it seems like a bug as you can get it to show "rise" if you fool around, but no adjustment and if you then push it again it will go back to duty and be locked there. only in trapezoid it works.
Yet another review on this product that does not use the maximum frequency and amplitude. If you want to test it properly, you need to see how it performs at it's limits. Also what is the lowest amplitude? IE: Can it output microvolts to simulate a received signal? Do the wave forms distort at it's upper limits? Looks just like the 6600 with upgraded buttons and power supply.
... its limits ... its upper limits Yet another comment made by someone who doesn't know the difference between the possessive pronoun (its) and the contraction of it is (it's) and it is i.e. not IE!
technically its the 6600 with the upgrades you mentioned. + grounded bnc's + firmware update via pc software. so yea, for raw performance tests you can reffer to a 6600 review. i couldnt measure the limits with my dscope anyways, since it was the limiting factor. but i did some tests / pictures with my new scope further down in the comments
I spotted the modulation of one channel with another, please can you tell me if you have used it (or checked) it with modulating an external source (eg: DTMF / voice / ) for both FM and AM ?
you can use the external input which goes from 0 to 5v to modulate the signal. ive used it for speech by having a 2.5v offset and a audio signal, fm modulated on a 4 cycle sine (custom waveform of 4 sine cycles made in the pc software, so output frequency is 4x whats on the display) set to 25mhz, i could hear stuff on 100mhz on my FM radio. didnt sound good actually.
Thumbs up for an excellent review! I just received my FY6800-60 yesterday and was glad to see your introduction before reading through the manual with it's interesting variation of English! :-) I was interested in whether you found an adjustment pot for calibrating the amplitudes of the waveforms, but you didn't mention it. One suggestion for future videos is that you might consider starting with the spectrum analyzer hooked up. This allows the viewers to see each mode as you're going through it without any obvious downside. I was afraid during the initial portion of the video that you weren't going to actually show the waveforms. Another suggestion would be to do a video on the PC software interface. I will be using this seemingly amazing dual channel DDS waveform generator to control a power amplifier for an ultrasonic sonar running at sub 100 kHz frequencies. The ability to have the two channels coupled with a fixed phase offset was crucial since I need to drive a differential TTL input to a dual power MOSFET gate driver. Normally it costs a lot of money to either buy a DDS waveform generator or even more to build a custom unit into the equipment. Thanks especially for verifying that the BNCs are referenced to earth ground. This would be assumed from the front panel markings, but Chinese equipment doesn't always get this right... Oh, and AWGN stands for Additive White Gaussian Noise, but at best it's WGN up to the frequency limits of the device, possibly generated using a fed-back shift register in the FPGA. By the way, the Cyclone IV is a rather powerful FPGA for use in this low cost equipment. Seems pretty remarkable that they can offer this functionality delivered to my door for less than $100...
thanks for your feedback, i will consider doing more indepth view in future reviews. funny thing is, the bnc's on the previous model were also marked as grounded, even tho it had a C7 plug, which doesnt even feature ground connection. lol but i found that the device isnt well EMI shielded.. well it had no shield but i expected less radiation. When setting it to 27.xx Mhz on CH1, some audible Tone on CH2 and FM Modulation and tuning into my SDR & CB Radio its quite a mess, even if the amplitude is 0V, those tracks after the DAC's radiate like crazy. Increasing the amplitude makes things just much worse. i think some copper emi shielding tape inside wouldnt hurt anyone. there were some pots inside, but didnt look further into it what they do. actually i did the teardown before the actual review. couldnt hold myself back. impressive what the chinese can do for under 100 bucks these days, id like to see more in future.
When I first got the package, I was immediately struck with how light it was. So I'm not at all surprised that there is no hint of shielding. At least they never claim to be compliant with any FCC or EU standards on EMI/EMC. I'm looking at just using the boards with control via the BNC so I'll be able to put the waveform generator in its own steel case. I just finished reading through the manual. The unit seems to have a lot of capabilities although the microhertz claims are a hoot! :-D There are a few strange items as well. The input impedance for the counter is 100 Ohms! Maybe they couldn't afford another 100 Ohm resistor to make it 50 Ohms? Or maybe they wanted to offer both a 50 Ohm input and a high impedance input and couldn't do it and compromised? Dunno. There was also this explanation for the power button: "When the signal generator is turned off, the indicator light will enter the breathing lamp state". But those are all minor things. If the unit allows me to generate a reasonable range of moderate fidelity waveforms in the sub 100 kHz frequency range, I'll be a happy camper!
no ch1 is the main signal, which can be modulated by either ch2 or EXT input. to modulate ch1 with ch2, ch2 has to be enabled. in the software there is no ch1 ch2, its main and auxillary channel, since all special functions like the adjustable pulse waveform, modulator and vco runs from ch1 only
In one of your answers you say that the unit has no sync/trigger pulse. Have you tried using a pulse output from ch. 2 as a trigger? Also have you looked at the sync output to see if that can be used?
@@gamerpaddy Yes I understand that ch2 does not give a sync pulse. I wondered if ch2 could supply a pulse at the same frequency as ch1 and could be phase shifted to act as a sync signal. Also do you know (have you scoped it?) what sort of signal the rear sync output produces? Your excellent video has left me very curious about buying one of these instruments.
Sync Out Outputs a 3.3v CMOS Signal with the set frequency of channel 1 divided by 2, in a sweep..it sweeps aswell. Its allways outputting it even with channel 1 disabled. Ch2 Runs Independend of the sweep a 1hz signal on it isnt sync with a sweep thats 1s long it even drifts slightly apart since its not exactly a 1 second sweep The only way this could Work is via a FM Modulation Set ch2 to a Ramp or exponential function with the Speed of your sweep like 0.1hz for 10sec. and Set ch1 to the Center frequency of your sweep range like 10khz for 0-20khz Then do a FM Mod in ch1 with ch2 as source. Set bias to your range (20khz) Then you can Trigger Off ch2's falling Edge But its phase ist drifting very slightly
no the original firmware is protected and cannot be read from a working controller, also it cant be donwloaded anywhere the only thing you could do, is reverse engineer your unit, learn stm32 programming and do the community a favor by writing a custom firmware for it.
Can anybody please tell me whether the FY6800 would be accurate enough for calibration and adjustment of an analog oscilloscope from the ealry 1970s? Or should I save and buy a more expensive unit? I have read a lot about this unit on the forums and here on YT - YT6800's problems with noise, jitter and other things. At the moment I can afford to spend around 300 Euros / dollars (260 UK pounds) at most on a Uni-T, Voltcraft, Rigol, Sigilent or Owon (or maybe you can recommend something around my price point). I would like the most accurate and precise instrument I can afford at the moment - I want to be able to calibrate other instruments and devices with it. Thank you in advance!
@@gamerpaddy Thank you, I eventually bought the FY6800 last September. I am very impressed with this magical box, all the different functions in a very small package. However, I will probably be using a professional calibration service to get my oscilloscope up to spec - the voltages required in the service manual are ridiculous. For example, the adjustment of input attentuators requires square waves at 10 kHz, 200 ns rise time, voltage in ranges from 6 mV to 80 volts!
do you think your scope is worth it? the tech in the 70s wasnt that good compared to later stuff.. 1960 was the year of the first ever transistorized oscilloscope from tektronix.. 10 years isnt much time to make a lot of progress. and for the price of a calibration you probably get something really good new or on the used marked thats allready more accurate than what your scope ever can be.
@@gamerpaddy You are absolutely right, but my thinking is a bit unorthodox. Of course it depends what will the calibration lab ask for the alignment, but it is a nice 2-channel 25 MHz scope I would like to have as my main scope (Philips PM3210). At the moment all I have is the inexpensive DSO138 kit. The Philips scope's specs are plenty enough for what I want to do with it - mostly audio work, some am receiver alignment. I am planning to get a decent DSO later.
i have had the Philips PM3100 and a tektronix t935 analog "storage" oscilloscope but since desk space wasnt quite there anymore and since i started repairing hifi equipment and doing digital stuff aswell, i went and bought a siglent sds1104x-e its capable of so much more, yes its digital but supports the usual analog stuff like display persistence, xy mode and such. plus you get automatic measurements, not just a trace on a screen where you gotta count the divisions. i havent tried the dso138 kit, but theres only so much you can cram into a repurposed mp4 player, but for quick n dirty work like checking if a signal is present and rough measurements they will do the job.
Can you tell me what the maximum sweep rate is? I have an older FeelTech that has a sweep rate of only 1Hz/s, while my Siglent SDG1025 will sweep .02Hz/s. I am wanting to replace my SDG1025 with something cheaper but need a better sweep rate than the 1Hz/s my old FeelTech has.
gamerpaddy Thanks. I'll have to do more research on that I guess. My old Feeltech also has a max sweep time of 999.99s, but regardless of the time the maximum sweep rate is 1Hz/s... if I set the time to 200s I can scan 200Hz but if I try to scan 199Hz it doesn't do anything. 1Hz/s is still a pretty good sweep rate but there's no comparison to my Siglent SDG1025 that will do .02Hz/s & more as I haven't found the limit on it yet.
how about using FM and a low frequency on the second channel? the main thing that annoys me on the sweep function is the lack of a sync/trigger signal.
How exactly do you test? go to sweep function, 0 to 200hz within 200sec right? and when going from 0 to 199 it doesnt do anything? well i cant reproduce the issue this ways it works for me.
gamerpaddy Ok- so it can sweep less than 1Hz/s....if you reduce the time but keep the sweep range at 200Hz how low can you reduce the time before it stops.
See your email. i didnt use a 50ohm load, not sure what load my siglent scope has. here are the photos i took. 28.5Mhz 5V, 36Mhz 5V, 36Mhz 20V (10V for the fft picture) www.file-upload.net/download-13353386/Photos.zip.html
