BK Precision 4017B DDS Function Generator
« on: July 10, 2013, 06:40:15 am »
I just put a best offer on a BK 4017B function generator on eBay and got it. It seems like a good general purpose function generator, I don't need much, just more than the old home-built opamp generator can give. I had been bidding on some non-DDS function generators, even the older BK 4017, but this wasn't going for that much more.

Does anyone have any experience with these? Not a whole lot of information out there on them.

I just got the function generator today and the 50 ohm output fuse is blown, it is a little SMD fuse with the marking F250 on it, which I assume is just voltage and gives me no useful information. I can't find a service manual for it, but I did email BK and asked if they could tell me the value of the fuses.

If BK doesn't respond, I'm going to have to determine a replacement for myself, would I be wrong in thinking that 0.2A would be appropriate since the output is 10V and 50 ohms?

F250 means Fast blow 250mA, so your assumption is more or less correct.

Makes sense, I was just assuming it was voltage because 250V is very common in fuses. I was also assuming the outputs would be fused differently, though that is based on no prior experience.

I need to find some kind of cheat sheet for SMD markings, I'm so used to through hole.

Thanks, now I just need to measure the thing so I get the right size.

Probably a good idea to get replacement devices for the output stage at the same time. Chances are pretty good the fuse didn't save them...

It appears to be outputting fine up to the fuse, just not through it, I didn't put a load on it though.
