Taking a look at the FeelTech FY6900 Function Generator from Banggood.
FY6900 Dual Channel DDS Function Arbitrary Waveform Signal Generator 60MHZ Affiliate link:
banggood.com/custlink/vGKR9r6RkR
Index:
0:00 Intro
2:48 Test Setup
3:55 Max peak-peak voltage test to 60 MHz
8:50 Duty cycle range
10:04 Phase adjust
10:52 Frequency meter/counter
11:22 Firmware glitch on measured frequency
12:27 Burst mode output
13:17 Modulation skim-over
13:32 Sweep mode
14:30 DC Offset Adjust +/- 12V
14:40 Output stage switching above 5V or below 0.501V
16:33 Higher freq. waveforms
19:05 USB Serial Control from com terminal
21:07 Conclusion
This cost effective little function generator makes a good entry level workbench addition.
There are 2 independent outputs plus a frequency meter and counter.
With built in arbitrary waveforms and the ability to download custom user generated patterns over USB, this generator can output up to 24 volts p-p up to 20MHz, or 5 volts p-p up to 60 MHz.
The unit can be controlled from a PC app or text commands over serial USB UART, allowing for automated control in test setups.
It's not intended to be a top of the line unit and it does have some firmware glitches (as of version 1.3.1, the frequency reported on the frequency meter may not always be correct) but for the price, as a learning instrument or a backup unit, it can have its place in the work shop.
