BNC Berkeley Nucleonics Signal Generator 845 Mini Handheld Cald! 20 Ghz Options

Description

This is for one bnc 845 mini handheld signal generator ranging 9khz to 20 Ghz!!

It meets almost all basic  specs according to bnc which we had calibrated and realigned a while  back! Comes with bnc cal cert and sticker. Was over 1800$.

But now performs quite well.

Please note it requires a special ultra low noise power supply for best performance . I have one I custom made for it. Or buy one from bnc for 100$.

Also for an extra 300$ you can get an even cleaner power supply(a big brick that outputs 120v) thus no line ripple which greatly affects the phase noise performance.which brings me to another point…. This model has a special low phase noise option and for a little 5 lb toy , this thing rocks pretty hard! Even at 20 ghz!

As you can see there are close in spurs which are as designed according to bnc. I guess it’s the trade off for such close proximity with the internal circuitry in a compact 5 lb lunchpail!  . But it really excels in mid range and far out purity for such a little thing! I’m very impressed!. Just don’t use it for any close-in work and you’ll love it guaranteed!.  The spurs are mainly due to the fan ..I’ll try to add a toroid and a cap onto the fans power supply and see if I can clean things up.ive had success with such a thing in the past. Check back. Meanwhile I’ll be using it a lot in our lab . It’s so handy and hopefully no one buys it soon 😉

The only real issues are there are some flurries(light noise transient signals occasionally like you see with many generators) but overall fairly clean.

It’s not perfect as any micro signal generator is that can hit this range but overall it’s somewhat impressive. It has internal pulse modulation . And a sweep function . I both freq and power sweeps. The interface is a lot bigger and easier to navigate once you train yourself on them, than hittite which only has a knob really!  The newest bncs have touch screen but they run about 20 to 25k$. So this is a steal. Also they make a GUI for it as it’s designed to be connected to PC to operate however also works seamlessly without all that. But for sweeps they told me that’s the way to go.apparently you’re supposed to pre program these and then recall the presets you make on the PC .
