GPIB Control of Systron Donner Synth

Andy G4JNT
 

I have a Systron Donner 1720   10MHz to 18GHz synth and need to know its GPIB command set.   I'm using a Prologix controller, and do have communications with the instrument as it will go into 'remote' mode, and keeps sending me [space] characters. 

 Tried sending it FREQ,  FRQ, F F123.4MHZ  FREQ123M  and many other variations on these,  plus all sorts of commands that other manufacturers' products will understand, but no joy.   Its sits there dumbly (still sending spaces)

Anyone have any ideas ? 

The Systron Donner Co.   got taken over by Gigatronics AFAIK , but nowhere can I find any reference to that particular product.   They seem to specialise in EW equipment, which seeing their location in Portsmouth is a bit of a giveaway.

The only similar product in the BAMA lists is the 1702 synth which is totally different and a lot older.  That is a 1GHz synth and has a crude simple GPIP instruction set.  I did try its command set (for what they're worth) but still nothing

Was hoping to be able to use it as part of a scalar return loss measurement system in conjunction with a diode power meter and A/D, so it looks as if I may have to go back to the original plan of using a D/A converter driving a separate YIG.  And the only YIG I have covering 10GHz needs a   -15V  0.5A supply rail - very irritating!

Re: Octagon LNB [1 Attachment]

Andy G4JNT
 

No, each side can do both H and V.

You power up either side with DC into the appropriate connector - they are completely independent.   V/H switching is done by changing the voltage on the feed.  12V gives one pol, 18V the other.
Then by superimposing a 22kHz tone on the IF on top of the DC the LO (can be swapped to high band.  SO in its proper usage one IF output can be any of hi/lo band / V/H    without affecting the other one

This describes LNB switching

I belive one is for H and the other for V  ..... but someone might correct me on that ,...........

I had a eurika thought the other day ,,,,,, but have'nt had time to check it yet ................

It's quite clear that the 27 Mhz crystal , oscillator , has'nt enought amplitude at the "output" pin , to enable lock , of the pll , but this is achievable with feeding in a 27 Mhz , signal from an external source .... at a larger amplitude , then lock is achieved ............

\I was wondering , if a resistor /choke in series , was fed to the "output" pin of the oscillator , on the chip , fron the 5 volt supply to the chip  ,..... would that increase the amplitude ????  it could be the missing link !



to Pin 20 , on the RDA 3560 IC ........ or has anyone else tried it ???

A question about the Octagon LNB....I’ve just received one via ebay.

 

Andy G4JNT mentions that there are two LNBs in the case. Does this mean there are two separate down converters, with each able to select H or V? Or one LNB  for H and the other LNB  for V polarization and a cross point switch to feed either polarization down each coax?

 

Just looking to see how easy it would be to feed a ref signal + DC  up one coax and the IF back down the other coax. I’ll take it to work tomorrow and strip off the gunge covering the screws and look inside more closely.

Hi there, 

 Thanks for all the replies....I will be in the Roscoff area from next Tues 19th till Sun 24th - I should be able to give a few hours notice , or the evening before. - I imagine early PM best for me...

I will work out some more detailed locators when I arrive...wx looks quite good!

I didn't have room to take the big system but will be interesting to see how it goes.

Hopefully internet should work at the house...I can use my phone in Brittany as well 07785744643 - some talk back would be good - not sure if you all have smart phones if /P

Re: Yahoo group web site very slow?

Graham G3TCT
 

DNS servers interpret the domain name you enter into its numerical equivalent. They may vary in speed as others have found, and they may also exhibit other undesirable features. A few months back I found that my internet was ludicrously slow in loading web pages. Inspection of the router's log showed an alarming number of DOS (denial of service) attacks. The source of these attacks was....... my DNS server!!! It was clearly infected with malware. I changed to 8.8.8.8 and hey presto all ok now.

Hi Folks,

 

Just to say I am taking my smaller DGU 3cm system [about 2w] and a Panel antenna over to Brittany from next Monday....I will be staying around the Roscoff area on the border of IN78 and 88...

 

I am over for a holiday but will hopefully get the chance to go to a few suitable spots for a couple tests....I will announce on the morning of any details...should have wifi in the house for possible skeds..

 

Not sure how many stations apart from Ralph ALY might be range...

Hope to be QRV on 24 and 76 GHz on Sunday, from usual QTH - Brown Clee IO82QL.
24 Ghz gear is a complete rebuild - so looking for a 'first' with it.
The 76GHz station is the UK uW Group loan set, which is also on its first /P trip with me. So hoping there will be SOMEONE in range to give it a try. Last month's trial was ruined by the weather, so that an intended test path from Brown Clee to Birdlip Hill never materialised.
Even the 'KST link is changed - going to try a mi-fi box, which (as always) works perfectly at home, but portable . . . .
Available most of day, depending on activity.
2 metre talkback (preferred) as well as 'KST.
Mobile: 07932 927887 (Home 01952 255416)
I am on my own this month, so please bear with me.
If requested, I may operate from somewhere totally different if this enables a 76GHz  test over a shorter path to take place.

That’s exactly the effect I had and is, as Murray comments, probably due to the BT DNS servers taking a very long time to find the Yahoo Ad and image servers – try changing the DNS on one PC from “find DNS automatically” to use 8.8.8.8 and see what difference it makes.

Seems to work OK On this XP machine.  I never had too much trouble anyway with the Yahoo Groups pages I visit from tine-to-time, ie UKUwaves and RSGBTech.   Other groups, however, did take a long time to load, so I assume that was a local caching thing

Anyway, using Google's 8888 DNS does appear to have made it all even faster
So Tnx.

Re: Yahoo group web site very slow?

Neil Smith G4DBN
 

OpenDNS is perhaps a better option than Google DNS, but the principle is the same.  The link below is very comprehensive.

If you can amend your own PC settings, just set the DNS server in PC network settings to use servers 8.8.8.8 and 8.8.4.4 for Google, or if, like me, you prefer OpenDNS, use 208.67.220.220 and 208.67.222.222. As a side benefit, OpenDNS offer a free home-only web filtering service.

If you don't mind amending your home broadband router config, the settings can be made in there instead, which fixes things for all users in your network.  Have a look in the setupguide. 

Just be aware that local name lookups might not work if you change the settings on your PC, in particular your broadband router/firewall/wireless box will not be accessible by name, only by IP address .  If you change the router DNS instead, everything will still work as usual.  Also watch out for DNS interception by ISPs, that can result in them diverting your DNS so they can insert adverts.  Nasty.  I use an Adblocker and No-script so I miss out on a lot of the slow advert and tracker things.

Hi Alan,

That’s exactly the effect I had and is, as Murray comments, probably due to the BT DNS servers taking a very long time to find the Yahoo Ad and image servers – try changing the DNS on one PC from “find DNS automatically” to use 8.8.8.8 and see what difference it makes.

Hi Noel an interesting comment. I am on the BT server for mail (not
BT-Yahoo) I find the on any group web-site the initial welcome page (with a
blank picture) appears immediately ....that says not a DNS problem to
me.....but wadderIknow :-)) The functions, most obvious by the correct
picture banner loading then, takes 85 seconds to appear and respond to
clicks. From then on response it reasonable. There is no internet activity
during this wait time. There is no variation in this by time of day so it is
unlikely to be congestion (I have a 50MB/s line)

Email message distribution seems fine but I get digests, though some other
groups show quite long delays distributing postings.

My thought is that Yahoo have removed server hardware bandwidth to make
their revenue earning operations seem more attractive for sale
(Cynical....what me??) Maybe they just want to discourage Groups.
