Default Function Generator?

I am looking for a function generator that can do 15 MHz and has sweep. Programmability would be nice but not a requirement. I would like to spend no more than $400. I found this one but have never heard of the brand.

Any recommendation?

Thanks,
Matt

I can safely recommend the function generators from Thurlby Thandar Instruments (TTi). Not sure how much they cost in the US though. I've used both TG210 and TG550.

Sorry, forgot about 15Mhz bandwidth. Try looking at Wavetek at eBay?

For your budget, you might consider two generators. One for low frequency (<5MHz) audio sweeping like a Wavetek, and an RF generator that overlaps and goes out to wherever. Though they are getting old and often need service, my favorite is the Wavetek 185 with two separate knobs to set the sweep start and stop points, combined with an HP8640B that will do every AM and FM alignment task you'll likely run across, up to, I think, about 500MHz. These can both be had within your budget, but some service will certainly be required. Good solid guaranteed units will be more. There are also Waveteks that will cover the range you want. The model 166 does everything you'd want out to 50MHz, if you can find one at a reasonable price.

The new unit you showed looks good too. There's a company that seems to make these things for everybody, but I can't find the name and site right now- I may have it at work and will list it later if it turns up.

Waveteks sound like a fun way to go. I saw a 148A on ebay that looks like it might work. I couldn't find any 166 or 185 though.

Is there a website that list the different Waveteks models and specs? I checked google and couldn't find such thing.

Thanks,
Matt
