Re: Measuring frequency on a 50W transmitter

John Miles
 


A great safety measure is to us a fused device on the counter input, to
protect it from excessive power. You could make one with a small
1/8 amp fuse, a
small box and RF connectors. Many commercial ones are also around.
The counter's input stage, whose geometry has about 1/1000 the size and
thermal mass of the fuse, will do a great job protecting the fuse. :) A
pair of back-to-back Schottky diodes, perhaps the kind rated for use in
switching supplies, might help if placed after the fuse.

An inline attenuator for the power/frequency range in question is really the
right way to go. Don't guess when it comes to protecting your test gear's
input stage. That's where we get all those auctions that say, "Removed from
a working environment! Powers up!!!11!"

Re: Measuring frequency on a 50W transmitter

Most VHF/UHF frequency counters use a terminated 50 ohm input, usually rated
at about 500 mW, and in this case, the fuse will provide protection, if you
do something that you shouldn't have done. If the input is a high impedance,
the fuse probably won't help, until the input melts.

Measuring frequency on a 50W transmitter

[email protected]
 

Gene, there are several way to get it done. You could transmit into an
antenna and put a second antenna on the counter, or you could get a 30 dB or
higher power attenuator and place it between the transmitter and the counter. I
have a 1 kW 40 dB attenuator that I use on my test bench, but these don't come
cheap!

A directional coupler would also attenuate the power into the counter, while
the transmitter power is going to a load. A sampling loop could also be
used, but it's hard to know how much power is getting into the counter input. A
loop can be made by getting a piece of coax that matches the counter input
connector, and making an insulated 1 inch loop on the other end, between the
center conductor and the braid.


A great safety measure is to us a fused device on the counter input, to
protect it from excessive power. You could make one with a small 1/8 amp fuse, a
small box and RF connectors. Many commercial ones are also around.

Happy Holidays to all list members!

Again, I must call for help from this great group.
I want to use my 5302A to measure the frequency of a high power transmitter (50 watts +), so how would this be done?
Would I construct some sort of 'RF pick-up loop and if so, how would I do it?
As always, I really appreciate the help.

Looking for HP 8505A spare parts. Anyone???

 

Hi to all
I've a 8505A RF/IF Unit (lower part) that needs some repair. Basically
I'm looking for some spare parts only and not a unit to salvage for,
but if there is any available out there I will give it a try...
However, now I'm looking for a pot, for the vernier of stop frequency,
a rotary encoder for frequency adjuster, and some other spares inside
the unit that might be hard to find. These are 2 connectors of 2x25
pins for the pcb slots positions on motherboard. At least a source for
them or any related info...
Thanks in advance

Re: HP8170a Information needed

 

I've got an 8170a and the Operating and Service Manual for it. It's
the typical HP O&S manual; about 2" thick and loaded with fold-out
pages. If there is something I can look up for you, I'd be happy to
do so, and, if anyone has figured out a good way to copy those fold-
out pages, I'd be happy to scan the thing in or loan the manual out
so somebody else can do the dirty work.

My 8170 is in very good shape. The battery was bad but didn't do any
damage to the board or surrounding components; it was in the "fuzzy"
stage, but hadn't leaked acid over anything. I need to rebuild the
keyboard, which is sticky, but otherwise it's quite nice.

Except, of course, that it's missing the output pods (15452a, 15453a,
15454a, 15455a, 15456a) - and so utterly worthless. I'm sure nobody
will be surprised, but I haven't been able to find them anywhere. Any
leads (no pun intended) would be appreciated.

Hi,
I've recently lost some of my storage space and am looking for a home
for a small collection of PCB's from various items of HP test equipment.
They are mostly from earlier solid state equipment. Collection
preferred, I'm in Christchurch Dorset, or postage at cost.
Anyone interested please contact me off-list

TCXOs, anyone?

 

Adding to the recent oscillator thread: Maxim has introduced +/- 1minute/year
(+/- 3.5ppm) at 0-40C integrated TCXOs (DS3234, for example). IMHO, that's
pretty darn good for something that fits in a 20 pin wide so package.

Does anyone have experience with their phase noise? As far as I'm concerned,
those are mighty good specs for such a small, non-ovenized package??

Cheers, Kuba

I'm looking for 00204-66538, that's the power supply assembly for an HP 204C
sine oscillator. Even a bare board would be fine. Mine is damaged from
battery leak and I'm trying to avoid rebuilding it.

gold plated boards

Greetings,

I have a few gold plated pcb's that I have stripped bare. How many boards do you need before you consider finding a gold salvage buyer?

Starting on page 20 of there's
a write up on it.



Might help you understand it better.

Hi,

Same dog bit me. I searched for info any never found it. The one I had seemed to work but had extensive battery leak damage. I scraped it for parts.

The 8170A is a fairly specialised bit of kit- I doubt it can be easily converted to do what you apparently want.
But I can send you a scan of the page it appears on ex the 1984 catalog if thats any use.

Wouldn't a swept frequency generator work for your purpose?
