Well, to be fair to Arthur, we can quibble with the presentation, but he's right. (I've always assumed he's using a handicap-accessible input device of some kind.) You asked how to run an 8640 from

Lothar thought that you wanted to drive one instrument with the other's scan ramp voltage. That would be a failure. If you can get the 8553's 1st LO into the 8601A, then it might be good enough.

The 8553B does not have a LO output jack, only the 8553L does. To use a non-option 007 8601A with the 8553B would require 8601A modifications and a special cable to connect to the 141T. Regards, Dave

Hi ZL4AI, Thanks for repply. I'm looking the manual and I'm looking the HP8601.....I havent the option 7. I have only a VTO OUTPUT connector,the LO INPUT connector is not mounted on the rear

The 8601A employs the same mixing strategy as the 8553, with a 200-310MHz 1st LO. Option 7 adds rear-panel jacks to the 8601A to accept the 8553L's 1st LO output in place of the 8601A's internal 1st

Look in the 8601a manual (read Option 7). There is provision to take control signal from the 8601, and use that to control the spectrum analyzer. The frequencies between the analyser and the 8601a

I found where the jumpers are located, thanks again. The answer that I was looking for. 73, Dick, W1KSZ/7

Thank you, I will look into that. 73, Dick, W1KSZ/7

I see your reputation for off-handed comments is well deserved. Too bad you have no clue what you are talking about and I don't wish to explain it to you. 73, Dick, W1KSZ/7

I am in Florida. For those in Au or the like with PAL, I could (I think) make PAL DVD's or just make the files available by DVD, if they're not too large. Harvey

They made movies? Wow Uber geeks!! I'd love to see them - I could xfer to dvd - but Australia is a long way to ship such precious tapes. Harvey White wrote:

The 8640B external reference can be configured to accept a 1MHz input, but the jumpers are deeply buried in the time-base module on A8A3. It is not necessary for the reference to be a sinusoid. It is

the first digits filled up with 0s usually lead to the unit, for example 08360-xxxx is from a 8360 series Geraldo Lino de Campos <geraldo@...> wrote: Usually there are HP YIG

Usually there are HP YIG oscillators or filters at reasonable prices on EBAY, sometimes identified by the board number. It will be very interesting to know the instrument they fitted, to be able to

a flip flop and simple low pass if needed is too much for an extra class ham to build up??

a flip flop with a low pass filter should work quite well at generating a nice sine wave go to tonne software and download his free filter design software you can

So basically what you are telling me is that it is not worth the effort to try and supply an external reference to the 8640B, yes ?? I have two TrueTime XL-AK GPS Receivers that have 5 outputs on the
