FeelTech FY6800 60MHz Signal Generator / Counter Review

A while ago I found myself in need of a signal generator (link below). Not having one I resigned to using the test output of my oscilloscope and conditioned the signal with a few parts. But now I’ve bought the latest and greatest from Banggood.

I put that brand spanking new Feeltech FY6800 through its paces. And I go into great detail about it. If you endure that one hour long video you’ll be able to operate that thing, know its limitations and are aware of its quirks.

Introduction …
00:00 Introduction – it’s going to be a very long video
01:11 In the box – the unit, various cables and a guarantee card
01:47 Comparison – to the FY6600 and Ruideng/JunCe JDS6600
04:02 Mechanical – lightweight and a wee bit flimsy
Handling …
04:57 Switching – power and channels on and off
06:59 Waveforms – more than enough
10:22 Frequency – setting it is straight forward
11:44 Amplitude – same as frequency
11:56 Offset – same as above
13:28 Duty cycle – same as above
13:48 Phase shift – same as above
14:14 System menu – not quite intuitive
Bandwidth …
15:08 Sine – up to 60MHz, with some jitter above 10MHz
18:18 Square – up to 10MHz, maybe 20MHz, some jitter above 10MHz
19:59 Triangle – up to 10MHz, maybe 20MHz, some jitter above 10MHz
20:31 Saw tooth – up to 10MHz, maybe 20MHz, some jitter above 10MHz
Parameters …
22:20 Amplitude – maximum 20Vpp
23:16 Offset – ±10V, but the output is limited to ±10V
24:49 Duty cycle – 0.001% to 99.999%, with oddities at 0% and 100%
25:48 Phase shift – 0.000° to 359.999° absolute, not channel relative
Advanced …
28:30 Modulation – everything you’ll ever need, at least I’ll ever need
35:05 VCO – frequency, amplitude, offset and duty cycle voltage controlled
39:14 Sweep – same as VCO, but timer controlled
Counter …
42:10 Basics – in fact very basic and with a delicate input, but it works
45:48 Principle – of operation, probably counting zero crossings
System menu …
48:04 Settings – menu with information and basic settings
49:51 Configurations – loading and saving them, lots of them
Conclusions …
54:05 General – works, (almost) meets its specs, good value
56:33 DC offset – it’s annoying, but maybe it can be corrected
