FeelTech FY3200S Dual Channel Function Generator - Safety Checkout

Too much difficulty with some of my vintage test equipment has prompted me to bring in a modern signal generator. Some users of this generator have reported a voltage on the terminals that may be dangerous to sensitive equipment or even to me. I need to check this out before putting it to regular use in my shop.

That Feeltech FS3200s NEEDS grounding, otherwise you will have 40-80 volts on the ground of the BNC! YOU'VE BEEN WARNED!!!!
There are plenty of RUclipss on this Generator.

He doesn't have all the settings set on the Feeltech!

Well the leakage current as f.ex. measured by XRayTonyB is 100uA (microamps!)
That is no danger to either a human, nor a circuitry if used correctly! First rule, you dont hook up this generator with the equipment powered on. Secondly, even if you do, any sensible person would connect the ground lead first. And at that point the generator is grounded via the DUT or both float up to the same non lethal potential of 40-80V @ 100uA
A Mr. Nilly-willy-pokey who does not care or think and connects the signal wire before the ground wire however deserves to run the risk of blowing up his gear. But at 100uA that is quite a remote risk even on transistor gear.

@@randomsteve4288 - Well I own one of these and WAS getting a shock until I tied all the grounds inside and put a 3-prong cable on the unit. nuff said!

Hi Jim, the impedance of the Signal Gen is 50Ohms, you need to also terminate with 50Ohms at the scope using a 50Ohms BNC Cable not the probe...

[@randomsteve4288]

If a signal generator drops the output voltage by a factor of 10 just because of a load mismatch, then it is totally unuseable.
Just imagine hooking this thing up to an IF strip via a "adapting" RC network; these network dont present a perfect 50ohm load to the gen. Or if you used a coil of some random wire to improvise an inductive coupling like shango does so often - I dont want to imagine what mismatch that complex impedance load would present to the gen. Or if you blasted the signal onto the glass envelope of a tube using a tube shield, you would basically be have the generator output unloaded.
All of these are everyday scenarios in which a sig-gen has to work without proper termination.
Nah, either his scope is broken or that "modern piece of equipment" is blending in perfectly with the other test equipment in that shop. Tho I also would not discount the possibility of his scope/scope probe being broken too.
On many many previous videos his scope had trouble displaying small signals even on the x1 probe and set to max sensitivity.
