I took a look at ebay to see if there was a manual for the U-Tech curve

got it and scanned it. The manual itself does not have real schematics.
I took a look in Google Patents for the year of the manual, 1968, and
found the patent, which does contain schematics and references to which
Tektronix scopes the 681 and 682 are used in. The 683 is a console
model.

I also found a bio of the inventor, William G. Dilley. He was an
amazing
member of the greatest generation. World War II fighter pilot, got an
engineering degree from University of Colorado, participated in various
missile programs, invented a bunch of audio gear as part of his
Spectra-Sonics Company. I didn’t find anything on U-Tech as a
company.

I just now sent a scan of the manual, with the patent and Mr. Dilley's
bio, to Kurt for TekWiki. I saw another post that Kurt is traveling but
I'm sure the manual will be available on Tekwiki in the near future.

Re: 16700A setting up Xwindows.

Richard R. Pope
 

David,
Yep! It is you. Sorry about the mix up on the name. I found a whole page of files for the 16700 machine. The B3920-13640 is listed as for the server and B3782-10101 is listed for the workstation under the OS columns. Wouldn't I want the WS instead of the Server OS? I really appreciate all of the help that I am receiving.
GOD Bless and Thanks,
rich!

I think that could be me! Are you referring to < http://perdrix.co.uk/hp16700/index.htm>?

if so the good one was on the HP_UX 10.20 install CD part number B3920-13640, not the HP image CD (B3782-10496).

However the page does say:

If you don't have the media, that could be a problem, so here is the original file:

< http://perdrix.co.uk/hp16700/sys.x11start>

You just copy (mv) that file to /usr/contrib/lib/X11/ after backing up the existing one ...

You can set up the network on the 16700 by running (as root) /sbin/set_parms initial

Do be careful if you configure some of the additional networking parameters. Don't configure the system as a NIS client if it's not been setup on the NIS server - you can end up waiting forever :(

Pete,
It starts up fine, runs the diagnostics, starts to load the 16700 Analyzer software and then the Display goes blank. The Monitor never goes in to sleep mode so I know that it is still receiving a signal.
When I shut it down the Display comes back and shows the Shutdown procedure.
Are you the person with the webpage that shows how to enable the good version of XWindows? If you are I followed your procedure as laid out on the webpage. I couldn't find the sys.X11start file and the link that you provided took me to what looks like a text file and I don't know what to do with it.
Will you please help me out of this? If I could find a set of Floppy files or Images I could put an all new OS on it. This machine was in a Corporate Environment and it did not use DHCP so I can't access it over my network. The software has been heavy modified. I used to own Amigas.

Pretty slick getting a 24" DSO screen. (hint: ssh in, then run the

they're back online now. You can add bash and ssh as well as gcc,

Adding ssh makes it very easy to copy files in and out. On my

be using a windows machine to access the LA remotely, use putty.

Re: 16700A setting up Xwindows.

 

Correction the Ignite CD (HP image CD isn't B3782-10496, it is B3760-14243))

If you need an iso of that reinstall boot CD for the 16700 series (16700_A0290.iso) I have a good one, but don't have the space on my website to store a copy

If you have somewhere I can upload it you’re welcome a copy.

One great thing about using a SD card is that you can write any image to it it and you
do not have to install the system from a CD or even need a CDROM drive. Since you
can keep the image as a backup you can fool around with all the settings and if you
really mess things up you can just restore the original image. Quick and easy!

Amigados and Workbench were based on Unix and Xwindows. Also I have been dabbling in Linux for decades. I learn very quickly and I am very good about following directions.
GOD Bless and Thanks,

Re: 16700A setting up Xwindows.

Paul Amaranth
 

I did get a CD from Agilent a couple years ago, but I do not believe
they provide them at this time. Back then they would send you one
free for the asking!

There is an iso image available containing the last release of the
software around on the web that you can write to a CD. At least
at some point, the one available off the Keysight web server was
corrupted, so be sure to get a verified good image (ie, somebody
says this specific image works).

If you have problems finding it, drop me a note off list and I'll
send you a CD.

Essentially, you boot off the CD and it reimages the entire LA.
Takes a while to finish; I seem to remember taking a couple hours
the last time I did it. (Did anyone mention that's not a screaming
fast processor in there?)

Re: 16700A setting up Xwindows.

cnc_joker
 

Get a SCSI2SD converter card instead. Worked great for me in my 16702. This uses
SD cards as the storage device so you are not locked into (very) old rotating media.

One great thing about using a SD card is that you can write any image to it it and you
do not have to install the system from a CD or even need a CDROM drive. Since you
can keep the image as a backup you can fool around with all the settings and if you
really mess things up you can just restore the original image. Quick and easy!

Re: What can you do with a 1502?

bonddaleena@aol.com <bonddaleena@...>
 

Hi. Several years ago, I, (for some bizarre reason) became rather obsessed with TDRs. I have 3 towers at my location with antennas from 160M through 70CM. I was able to accumulate a LOT of 1502 and 1503 TDRs, in addition to a bunch of Biddle, etc.

When I install a new antenna, I always make several runs with the HP TDR and it's printout.
I then store it and go back every year or so, to see if things have changed.

Yes, the batteries are NFG and the TD are problematic. However, through ePay, I have scored a bunch of NOS TDs from both HP and the Russian equivalent.

Turned out I had an immediate need for it to measure how much coax I

getting an answer without having to string the cable or unrolling
the entire reel and finding out I'm a foot short.

Anyone have any neat applications for one of these, other than the
obvious ones of finding cable breaks and identifying where connectors are?
Not just breaks, any discontinuity. I've used it to diagnose a fault in a
relative's 75ohm TV antenna feed, where one multiplex couldn't be received.
There was a bad kink 4m into the cable, and the impedance change notch filtered
the multiplex's frequency.

Given the resolution, it can also be used to diagnose impedance variations on a
PCB; that's obviously not possible with the 1502B or 1502C.

Occasionally, since it my fastest scope by about decade, I'm tempted use it to
measure the risetime of my step generator. Obviously extreme care would be
needed to avoid damaging the TD, but I think it could be done.

And, shades of Dennis Tillman, vendors at hamfests are beginning to remember me :)

The 1502s are sweet little things.

It IS a different product number, so "apples and oranges?"  I don't know.  I suspect a bad bowl of chili from the tube or nozzle supplier to NGC.

Not just breaks, any discontinuity. I've used it to diagnose a fault in a relative's 75ohm TV antenna feed, where one multiplex couldn't be received. There was a bad kink 4m into the cable, and the impedance change notch filtered the multiplex's frequency.

Given the resolution, it can also be used to diagnose impedance variations on a PCB; that's obviously not possible with the 1502B or 1502C.

Occasionally, since it my fastest scope by about decade, I'm tempted use it to measure the risetime of my step generator. Obviously extreme care would be needed to avoid damaging the TD, but I think it could be done.

And, shades of Dennis Tillman, vendors at hamfests are beginning to remember me :)

The 1502s are sweet little things.


Re: 16700A setting up Xwindows.

Richard R. Pope
 

Hello all,
Mine is a NEC 3x that uses a CD Carrier. Remember those!! 16700s do not have Displays. This is from an expert that explained the terminology to me. The As came with Ethernet 10baseTs and no CD-ROM drive. The Bs came with 10/100baseT and internal CD-ROM drives. Mine is an Opt3 which means that the Graphics have been upgraded.
Yes, I made it where I can no longer run the Analyzer. This has more to do with the way the machine was heavily customized. So if someone could please help me to take this back to day one and rebuild the OS from scratch it would be really appreciated?
GOD Bless and Thanks,
rich!

Another one is Yamaha, can't remember the model, it is the one SUN

I also added a larger/faster hard drive to mine. Gcc wouldn't fit on

I've been attempted to try a SCSI<->SCSI80 adapter and see what happens

got rid of the session manager
There is a display-less version of the 16700's.

It's an interesting box if you're familiar with Unix and/or HPUX. I've
hacked mine significantly, got rid of the session manager (which is a
real pig on that small machine) and use it remote. Pretty slick getting
a 24" DSO screen. (hint: ssh in, then run the bare app with the DISPLAY
variable set). Don't use vnc, that just gets you an image of the
LA desktop.

That's HPUX 10.2 and there are additional binaries you can load. For a
while the Merjin archive had dropped the 10.x binaries but they're back
online now. You can add bash and ssh as well as gcc, perl and a few
others.
Adding ssh makes it very easy to copy files in and out. On my network that
was a mandatory add. If you're unfortunate enough to be using a windows
machine to access the LA remotely, use putty.

All that said, if you're not familiar with unix, just accept the UI they
give you and learn to work with it. For me, having a computer that runs
an LA app is more useful than an LA that happens to run on a computer. But
I've been building Unix systems for 30 years and can pretty much make
them do whatever I want.

The 16700A is a piece of T&M that uses HPUX as its base control software

changes in the startup sequence can cause I/O modules to stop working as

Your prompt is pretty much common for a system without a host name, in
the
case the unknown is where the host-name would go

If you want to continue using it as a LA, I would strongly suggest not
changing the display and just get use to it.

Re: Where to find a serial number on a 335 Sony/Tektronix

Phillip Potter
 

Then it fell off... there is a slot, but no SN plate.

You can see that, here:

https://groups.io/g/TekScopes/album?id=33014


so, I guess the search is over.  Come to think of it, I have a vague recollection of the SN tag there, on my previous 335.

Thanks, Paul!

Hi all,

I searched to exterior, and the interior, but could not find a SN for my
335.

The reason for the search is, I have two 335 manuals a want to figure
out which one to keep.  One has part number 070-1943-*00 *and the other
is 070-1943-01. I figured that I would need the SN to tell which manual
is more appropriate.

I did see that there was a date of 1973 on the etching on a board
inside, so that gets me closer.  BUT, still no joy!

Thanks,

Phil

Re: What can you do with a 1502?

Paul Amaranth
 

Thanks Harvey, I'm aware of the TD issue. Frankly, I was surprised that
it was OK.

There was a thread on eevblog where one fellow used a Russion 1|308E as
the 20mA and a A|201V for the 10mA diode. Sorry, I can't get the Cyrilic
in correctly. I have a pack of the A|201V, I think. You can get 4 of those
for $9, maybe less, on ebay (search for au201v). Haven't found the 1|308Es yet.

Here's the eevblog thread:
https://www.eevblog.com/forum/chat/tektronix-1502-tdr/

That was 4 years ago. Some other ones might work.

Thanks for the pointer Dennis, I'll track down a copy.

You are quite lucky. The tunnel diode is very fragile and directly
connected to the BNC. (I'm thinking of the 1502, not sure about the
later revisions). There should be a shorting BNC connector that needs
to be on at all times unless you're doing a measurement.

The tunnel diode can be damaged by DC (a typical damage scenario) or
by RF transmitted into the TDR.

The 1503 is harder to damage, doesn't use a tunnel diode, has a
different presentation on the screen, but is for cables about 10x
longer.



Turned out I had an immediate need for it to measure how much coax I
had left on a roll (answer: exactly enough to do a job). Pretty handy

Determining the velocity factor of the cable, for one. I think you
can also determine the impedance of a cable as well.

Again, be really careful with this, simply because the tunnel diode is
unobtainable (period, sincerely yours, etc....). There *may* be a
Russian equivalent, but I've not heard of one offhand.

Mine needed battery packs, too.

Harvey
