Re: Which Tektronix Signal generator?


 

¿ªÔÆÌåÓý

I have an HP 8660D which I like. It uses plug-ins and will generate signals up to 2.6 GHz with the right plug-ins (and the 11661B optional frequency extension option). I also have a couple of 8660Cs which I need to sell. These units are very heavy but work well. You can look at the specs for the C in a mid-80s HP catalog; the D showed up in the late 80s, IIRC.

Two points .... first, you need to get a unit with Option 002* installed. ?This option gives operation from 512 MHz to 1024 MHz. ?Without it, the generator will INDICATE the higher frequencies, but will have zero output.

Second, the plastic gears inside the HP8640B are known to be fragile, and if they break, the repair is non-trivial. ?I understand there's a fellow who can provide brass gears, but I haven't looked into this yet, as neither of my HP8640Bs have failed. ?Yet.

Other than that, these generators are superb instruments.

* Major options are:
001 -- enhanced AM modulation
002 -- expanded frequency coverage
003 -- 25W reverse power input protection

To get up to 1GHz, you cannot go wrong with a HP8640B for your application.? Of course, it's not on the light side, but does fit pretty nicely on a modest work bench.

I am trying to narrow down my choice of a signal generator for my shack.

I would be glad to have your opinion on which Sig Gen to buy
I need something that covers from 0.01 MHz to 1000 MHz or preferably up to 3000 MHz. If the sig gen goes up to 1000MHZ a second set to cover 1 to 3 Gig would have to be purchased later. At the moment I have several oscillators to cover the 1 to 3 Gig range. Carrier noise better than -80DBc at 10 kHz would be okay. Nothing too fancy but sweep capability, AM and FM is needed.

I do not want to buy a very heavy post world war device although I admire them and have a few RT sets from olden times. I have to have it courier shipped to Pakistan and THAT costs.

Prefer Tek or HP, and something for which I can get the service manual which is a must have.

I will be using it to play around with building transmitters and receivers for my ham gear.
