Hmm, I just today joined this group, and also in the last couple of days killed my cash reserves buying some HP gear; a 4140B pA meter, a 4192A? impedance analyzer, and a couple of other big heavy HP things. Shipping of which is going to be a real $train. I'm in Sydney Australia, use a reshipper in Hawthorn LA Calif. Now I read this. How is that 8594E part-out going? Because... I have a sick 8594E, my first ever spectrum analyzer which was bought as working last year, but wasn't. Trouble is I don't yet know what's faulty, the repair is stalled, and I can't afford to make an offer for your entire one. Awkward timing. The story is here: http://everist.org/NobLog/20190223_full_spectrum.htm

Do you still have the 8594E?

Does 8594E have tracking generator..?

Hi all
?
During the last year on a number of sites I
have seen several requests for people buying their fist spectrum analyser and all
have spoken about wanting a tracking generator
?
I personally have only used an analyser
with a tracking generator a few times in my life and that was 35 years ago a
Marconi 110 Mhz spectrum analyser for setting up IF ?filters
?
In my early days I started using swappers
and diode detectors or power meters with an oscilloscope then moved onto Scaler
analysers
?
Could it be the new people are not familiar
with other test equipment and think a spectrum analyser is the only tool they
require and unaware of sweepers and Scalier analysers
?
Your comments please ??Regards
Paul

Hello Paul,
nah, I think it is a combination of:
a) lack of green
b) lack of space
I sit on 65m2 dedicated lab space, and it is barely enough.

A Spec An and sweeper and an external 3dB hybrid to act as reflectometer enable such a wealth of measurements that I’d be lost without the tracking gen. Surely
it can only be lack of demonstrations showing people what can be done with this combination that is the answer to your question.
?
People will have read my comments about calibrating the 8920A. For something robust enough to survive in the boot (sorry – trunk) it is always with me at ham
radio events and at the gliding club where I get to test and repair many things such as UHF ground radios, VHF airiband radios, aircraft 866MHz FLARM systems. Oh, and the remote Davis Vantage Vue weather station – we have it operating at 2km range with >99%
uptime. The 8920 is the goto instrument and always has the hybrid hanging off the front for measuring all of these types of antenna. No sweeper? – non starter. Shame it stops at 1GHz.

FLARM is an aircraft collision warning system. Each end knows where is it by GPS and every second transmits is location, velocity and heading on a common channel.
?
Approaching aircraft hear the pings of other FLARM equipped aircraft an calculate whether there is going to be a collision. If it thinks there is danger it
beeps loudly to the pilot to take avoiding action. The beeps get faster as the nature of the danger increases. It is generally regarded that if you get a beep it is a failure of lookout, but lookout is never perfect and all pilots get beeps. Glider pilots
fly for miles towards good-looking clouds and hence find themselves unwittingly ?flying toward each other. In the Alps gliders fly in the updrafts very to the mountains and meet other aircraft head-on as they go around corners – it was that community that
first developed FLARM. It’s a life-saver.
?
The glider antenna installation is generally a monopole and ground plane somewhere in the dash in front of the pilot. The usual installation errors I get invited
to diagnose are owing to short range and arise from antenna de-tuning by nearby objects, noise from other equipment, (mostly data lines and switching PSUs), and obstruction such as by parts of the aircraft made of, or repaired in carbon fibre.
?
Sometimes its hard to get away from playing radio to actually get to go flying. Lol

Approaching aircraft hear the pings of other FLARM equipped aircraft an calculate whether there is going to be a collision. If it thinks there is danger it
beeps loudly to the pilot to take avoiding action. The beeps get faster as the nature of the danger increases. It is generally regarded that if you get a beep it is a failure of lookout, but lookout is never perfect and all pilots get beeps. Glider pilots
fly for miles towards good-looking clouds and hence find themselves unwittingly ?flying toward each other. In the Alps gliders fly in the updrafts very to the mountains and meet other aircraft head-on as they go around corners – it was that community that
first developed FLARM. It’s a life-saver.
?
The glider antenna installation is generally a monopole and ground plane somewhere in the dash in front of the pilot. The usual installation errors I get invited
to diagnose are owing to short range and arise from antenna de-tuning by nearby objects, noise from other equipment, (mostly data lines and switching PSUs), and obstruction such as by parts of the aircraft made of, or repaired in carbon fibre.

Sometimes its hard to get away from playing radio to actually get to go flying. Lol

Hi colin
?
OK on portability by the way I always put instruments with a tube on the back seat so as not to brake the tube
Ok could you please explain
aircraft 866MHz FLARM systems
?
And yes the tracking generators I have only go to 1300 mhz
?
Regards Paul

A Spec An and sweeper and an external 3dB hybrid to act as reflectometer enable such a wealth of measurements that I’d be lost without the tracking gen. Surely
it can only be lack of demonstrations showing people what can be done with this combination that is the answer to your question.
?
People will have read my comments about calibrating the 8920A. For something robust enough to survive in the boot (sorry – trunk) it is always with me at ham
radio events and at the gliding club where I get to test and repair many things such as UHF ground radios, VHF airiband radios, aircraft 866MHz FLARM systems. Oh, and the remote Davis Vantage Vue weather station – we have it operating at 2km range with >99%
uptime. The 8920 is the goto instrument and always has the hybrid hanging off the front for measuring all of these types of antenna. No sweeper? – non starter. Shame it stops at 1GHz.

Hi all
?
During the last year on a number of sites I have seen several requests for people buying their fist spectrum analyser and all have spoken about wanting a tracking
generator
?
I personally have only used an analyser with a tracking generator a few times in my life and that was 35 years ago a Marconi 110 Mhz spectrum analyser for setting
up IF ?filters
?
In my early days I started using swappers and diode detectors or power meters with an oscilloscope then moved onto Scaler analysers
?
Could it be the new people are not familiar with other test equipment and think a spectrum analyser is the only tool they require and unaware of sweepers and Scalier
analysers
?
Your comments please ??Regards Paul

Does 8594E have tracking generator..?
May be interested in TG parts...

Hi Dave
I think you have it !? ? it is the tracking generator obsession
As we have only had one person com back saying he requires it but shame it only goes to 1000 mhz? I would think the minimum now days would be 2000 Mhz for sat comes IF work
Regards Paul

I have used HP tracking analyzers at work almost daily for many years. Last year I acquired one surplus that needed minor repair for a stupid low price. I also own a Midnight SNA and NanoVNA. And a vintage Eico sweep generator. :) Each tool has its own niche. Each is plenty good enough for most hobbyist needs within those niches. The HP continues to be my favorite instrument and my go-to for sanity checks on the others. And yes, I do use the tracking generator in radio service work. I likely would not have purchased this HP if it did not have the TG. And then there's always the street cred that comes with using a name brand instrument.... :D 73 -Jim NU0C On Sat, 25 Apr 2020 10:59:31 +0100 "Paul Bicknell" <paul@...> wrote: Hi all
