Re: [Elecraft] OT: Test Equipment
Not sure what you plan on using it for, but you might just be happy with your antenna analyzer output. Antenna analyzers I've looked at (MFJ-259B, AIM4170B, AA-200) have a pretty well regulated RF output level across their full range. The MFJ-259B and AA-200 have 2Vp-p output levels, and the AIM-4170B has about a 20mVp-p output level. The MFJ-259B drifts around a lot, and needs to be run from a fixed voltage external power supply for best frequency stability after warm-up. The AIM4170B and AA-200 are synthesized and let you sweep as well. The AIM4170B even lets you zero its accuracy to WWV. Then all you need are some step- and/or fixed-attenuators to get the level to where you want it. I'm sure that the phase noise isn't HP-quality, but you can do a lot of normal ham-stuff. I use the high level outputs with an oscilloscope for filter work. Phil - AD5X___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

If I were to buy a RF signal generator off of Ebaywhat is a good one to buy? I don't want a WWII surplus RF signal generator and do not want the 10,000 dollar one either. I would like to have a transistor RF signal generator so that kind of leaves out the old Heaths and Eicos. Does this august body of homebrew swamis have any suggestions?

Re: [Elecraft] OT: Test Equipment
HP8640B is the generator of choice for (a) low phase noise and (b) more or less affordable (in the $1K and less category.) That being said, these generators are now well over 20 years old and are notorious for mechanical problems associated with switches and tuning gears. I would not purchase one unless you are prepared to do some work on it. If a switch or two isn't broken when you buy it, it soon will be. These are very complicated mechanically. If your budget will stand it, I would purchase an HP8657B, or, as a somewhat less desirable unit, an HP8567A. Both are synthesized signal generators and are free of some of the problems that have been found with their lower price brother generator, the HP8656. The phase noise and spurious outputs of these synthesized generators are much inferior to the 8640B. They are, however, fully synthesized, and can be remotely controlled over an HPIB interface, neither of which is the case for the 8640B. I have a pair of 8640Bs and a pair of 8657A's. Both 8640B's have mechanical problems that, fortunately, I can live with as I am not all that good at complicated mechanical repair work.

Re: [Elecraft] OT: Test Equipment
The K-3 uses direct digital synthesis to get its frequencies, why not you? For those of you who want to do a little HBing . There is a direct digital synthesis RF generator kit from the below for under $30. Upper audio to 60MHz with at least 1 Hz resolution. Fits in a tiny minibox. http://www.amqrp.org/kits/dds60/ You need to be able to assemble SMT stuff. You also need to provide an attenuator since it puts out several volts. There is a free parallel port based program one may use to generate the programming word. It can run for 10 hours on an eight pack of rechargable AA NIMH batteries . Several alternative ways of providing the programming word are given in the documentation. The alternative ways involve PIC's and some programming-- not for everyone. I threw together an alternative using a BASIC STAMP, STAMP floating point processor, an LCD display and pushbuttons for input. Works for me. The unit drifts initially about 50 Hz and settles down to be as stable as the K3 in about half an hour. Recently used it ( + 80 db attenuation) and the FILTER tools program described in posts on this reflector to generate a bunch of filter plots. Worked very nicely. Held it's frequency within 1Hz for the whole series of filter runs. I have no financial interest in AMQRP or the DDS-60 product. 73 de Brian/K3KO Don Wilhelm wrote: Lee, Assuming you want quality without a lot of expense, I would wait until an HP 8640B shows up. 500 kHz to 512 MHz CW or AM (some have FM capabilities). They are well shielded and the output attenuator is calibrated - goes from +20 dBm to -130 on the fixed attenuator and can be reduced to -140 dBm. There is some warmup drift that lasts for as much as 2 hours, but they do settle down to a very stable frequency. There may be newer signal generators that have the same performance specs, but this is an old favorite of many. The only major problem I know about is reports of broken gears - mine does not suffer from that problem (yet). 73, Don W3FPR Lee Buller wrote: If I were to buy a RF signal generator off of Ebaywhat is a good one to buy?

Re: [Elecraft] OT: Test Equipment
If you can get by with ham-band only frequency coverage, what about using the K3 + KXV3 + some attenuators as a signal generator? You could even forgo the KXV3 if you have attenuators that can handle 100mW. 73 -- Joe KB8AP On Jan 22, 2009, at 11:02 AM, Lee Buller wrote: If I were to buy a RF signal generator off of Ebaywhat is a good one to buy?

Re: [Elecraft] OT: Test Equipment
You might want to check out the siggen in this months QEX. It has I/Q output up to 200MHz. Output level is settable and controllable. And if you need low phase noise, it has provision for an external low phase noise clock. It's also small and light; can be controlled by a pc or external microprocessor.
