I like you didn’t replicate the same information capably presented by other reviewers. Your impressions of the usefulness and operational characteristics from your chair are most valuable to me. As a hobbyist, and new one at that, I don’t have much of a budget for “nice to have” but not essential kit. I appreciate your frank comments as what to expect from this unit.
"Bode plots" are mentioned a few times in this video, pronounced with a silent 'e'. However, the correct pronunciation is the way their inventor, Hendrik Bode, said his name, as "boh-dee".
I found using the VCO with a cable from Ch 2 was messy and not accurate. From what I've seen, the response of the VCO isn't quite linear and mine had to be pushed slightly over 5 volts with the ramp to reach the end frequency. The offset was also slightly off.
I’ve had mine for around a year now, it’s pretty great other than the lack of a power switch on the front panel. I’m not a fan of devices that “sleep” as does this, being used to older stuff that might decide to burst into flames in the middle of the night. I mainly use it as an RF generator for aligning AM radios, and it accomplishes that task very well.
thank you. I power up my fy6900 almost ever over the usb port - that works perfect. The ratio between price and usability ist very, very good and i think for hobby and educational purposes it is a nice product.
To reach the same functionality you can use the modulation of the fy6900. Only the freqence setup is slightly different. It can be set the middle freqency und a span. Its useful to find the center frequency of filters. The sweep rate configuration is simular to your setup, means CH2 ist set to ramp of 5V.
I’m thinking of purchasing one of these, but can I ask it is capable of outputting a 455khz tone mod at say 30%. So you can align IF stages of a transistor radio ie Roberts rambler ?
I haven't purchased one of these FY6900 units yet, but I am VERY close. Some interesting ideas for doing frequency sweeps for filter and Bode plot measurements. The FM modulation idea from fredsmith5473 looks promising. I was wondering about another idea...
Thanks for this interesting video. I too have a FY6900.
do you recommend for a student and hobbyist man? Thank you good video.
Another great video Bill.
I had my one going for calibration and I had it at Hz and now it’s at MHz and I don’t know how to change the frequency to go back to hertz damn. Anyone can help?
Can this generator output an AM modulated signal, say 600Khz w/ 1Khz Mod?
On your way to 1k, huh?

Why do you need so many different devices? Are you a collector?
