HP3577 won't plot marker

Hello Folks,

No big deal because I can just add it in via graphics software, but a
puzzler: My HP-3577A plots everything just peachy, except for the
marker. It's a fat dot and very visible on screen, after plotting ...
poof ... gone. I am going through a Prologix adapter into John Miles'
HP7470A software although that shouldn't really matter. Oh, and yes, I
am using "Plot All" on the instrument.

Does anyone have an idea why?

Am guessing the software scans the original like an electron beam in a
CRT, and PenUp, PenDown commands are made when appropriate.
So, all lines become horizontal (dashes, if you will) and vertical
lines cannot exist; Fat "dots" would translate to a short line and if on
an axis would thus be "ignored".


Good point. It should be a circular thing though, line going on a
radius, several times at increasing radii. But maybe the SW doens't
follow that. Because the instrument sends it, back in the old days with
the HPGL plotter it plotted with the markers.

On the 8753 Network Analyzer the print/plot menu had all the items of
a plot either enabled or disabled. You could turn on/off the grid,
the various traces, markers etc.


I had them all on. For some reason it plots all, grid and everything,
except for the marker.

I will state the obvious :)

You mean "Is it plugged in"? :)

1. Try reseting the instrument


I did that several times, including da big reset (power switch).

2. If you are using the old marker type plotters make sure the
cartidge has the pen loaded :)

It's on the same pen as the traces (which plot fine) but I am not using
a plotter, I use a software program that can store in GIF because
"modern" word processors cannot import HPGL anymore. With the old
plotter it worked. Well, it wasn't a real plotter but an HP inkjet
printer for lab instruments that just behaved like a plotter. I think it
was called ThinkJet or something like that but it died long ago.

You say plotter instead of printer ... are you using the old marker
plotter?


I use John Miles' HP7470A software via a GPIB adapter that translates it
all to USB.

Maybe, used to be able to "read" HPGL. If you can capture the output
stream sent to the "plotter" maybe i can tell you what is going on.

I don't have a 3577A around here, but I do have a couple of test plots
from other users, and the markers are visible in them. Send one of
your .plt files to jmiles (at) pop.net, and I'll have a look at it to
see what might be different with yours.

I hadn't kept the PLT files because GIF is easier to handle. Can't get
to the board easily now so I just took a noise shot and set the marker
on a dominant peak, then sent it to you via email. At least in the GIF
file the marker is gone. But don't spend much time with this, it's only
cosmetic because most instruments sucha s the HP-3577 also list marker
position and amplitude in text.

You might also try the demo release from www.printcapture.com to see
if it can render the marker. If not, you may be dealing with a
firmware bug.

Very possible that the marker doesn't come out of the HP-3577 anymore.
It used to, but I guess the warranty on that one is up :)

Hopefully this doesn't mean the EPROMs are losing it ... Note to self:
Get EPROM programmer.

Ok, didn't have the original plot files anymore but here is one with
noise and the marker at 108.5MHz. Not sure if it'll make it via Usenet:

Hello Folks,

No big deal because I can just add it in via graphics software, but a
puzzler: My HP-3577A plots everything just peachy, except for the
marker. It's a fat dot and very visible on screen, after plotting ...
poof ... gone. I am going through a Prologix adapter into John Miles'
HP7470A software although that shouldn't really matter. Oh, and yes, I
am using "Plot All" on the instrument.

Does anyone have an idea why?

Well, folks, John Miles (the author of the software) found the cause.
Seems the older version I had does indeed not display the marker but the
new one does. So all is well in the land now :)

Thanks, John. And thanks to all other for the hints.

Ok, didn't have the original plot files anymore but here is one with
noise and the marker at 108.5MHz. Not sure if it'll make it via Usenet:

As you might see there are several munged characters, but the marker is
clearly in the file at the stated frequency and at -87.777 dBm.

The munged characters prevent HP 7470A Emulator form plotting the file.

Possibly the Usenet channel munged them because it plots alright. But as
I wrote, John Miles already figured it out. The reason was that I had an
older version of the software which won't print the marker for some
reason. The new version does print it as a non-filled circle, not
completely filled like the printer used to but it is quite visible.

Ok, didn't have the original plot files anymore but here is one with
noise and the marker at 108.5MHz. Not sure if it'll make it via Usenet:

It did, and it didn't. Some parts plot OK, but the LB statements are
munged, since they use an ETX (ctrl-c, 0x03) character as end-of text,
which Usenet apparently strips.

Spurred me on to get hpgs (http://hpgs.berlios.de) to compile and run,
finally.

As you might see there are several munged characters, but the marker is
clearly in the file at the stated frequency and at -87.777 dBm.

The marker *legend* is there:

LBMARKER
108 500 000
LB.000Hz
PU;PU;PA 838, 1929;LT;DR 1, 0;SR 1.119,
1.758;LBMAG(R) -87.777
LBdBm

and plots as text, more or less in the right place at top of screen.

The actual marker, described by Joerg as a "fat dot", isn't.

I was wrong about Usenet munging the ETX characters. They are there in the
posting, but copy-and-paste won't carry them across, at least to any text
editor I have. I found another way of saving the file intact.

HPGS plots the whole thing with the exception of no fat dot. I can't see
any circle or fill commands that might be it, in there.

If anybody's interested, I'll post a PDF of the plot result to a.b.s.e.

Thanks, Fred. But as mentioned in a direct response to my original post
John Miles (the author of the HP7470A software) has found what was
wrong: The old version of the software won't render the marker but the
newest version does.

That still leaves the issue of transmitting the control characters
cleanly. Could you uuencode the file and resend it?

I just sent the file to you per PM attachment, that should send it
cleanly. But again, it's not an issue anymore, the problem is now solved.

Thanks. I wanted to see how the marker shows up with the 7470 emulator.

Out of interest, how is the marker encoded?

To be honest, I don't have the foggiest idea. But I think Joseph wanted
to take a look.

It is actually fairly straight forward. HPGL was intended to be humanly
readable as well. The marker is near the end of the file. Perhaps you
can just read it. Ask if you find something too obscure.

It'll probably be a circle with fill.

A CI instruction followed by an FT instruction.

I see nothing like that in the file that Joerg provided, which,
incidentally, plots fine using hpgs. I haven't tried it on my "real"
7475A plotter, but I intend to.

I *may* have found a bug in hpgs. Files from an HP scope plot fine direct
to plotter, but hpgs stairsteps the settings text atvthe bottom. An
embedded LF in an LB instruction does a CR *and* LF on the plotter. In
hpgs, it just does LF.

Joerg's file plots fine, now I've got a couple of spurious newlines (wrap
effects) out of it.

I'll post it as a .pdf to A.b.s.e.
