Hi Charlie, Maybe you can answer this...

Is a preceding ringing voltage required to get your CID display to
work, or is the Channel Seizure preamble what resets it?

Without experiment (which is always a bad thing to do) I'm musing
whether blanking first ring prevents the CID from functioning.

...Jim Thompson

That depends on if you want any downline equipment to see CNID.
Ringing voltage is used as the wake-up and look for the recognition
equipment.

That's my understanding also. So how do I activate "downline"
equipment?

Alternatively, you could re-insert CNID.


I thought of that... fits nicely as a block in my diagram. But how do
I do a block that re-inserts?

I would use a controller chip over discretes. For one thing, the long
tail pair matching in the error amp will be better over discretes.

That is absolutely true.
However we should never forget what we use it for,
and high accuracy is not really a big thing here.
What counts is that I have the transistors laying about :)
I am actually working on something like this, as a ripple filter
stage coming after a switch mode computer supply for 25A or so.
The idea is to do AC peak detection on the _output_, and then
use that detected voltage to create a voltage drop (low) over
the series regulator, so that drop is just enough to filter out the ripple.
Dunno if that ever has been done, you cannot go for 'zero ripple',
but set for example for 1 mV or so.
Computer switchmodes are really really noisy, and this way you minimise
losses, so for 1V ripple drop the 12V PC supply to about 11V ripple free.
Will try some simulation tomorrow perhaps, and yes, that uses a LM324 opamp,
not a long tailed pair.
Click to expand...
The nice thing about controller chips is a thousand customers have
flogged the design by the time you get to use it. There are always
gotchas that one person may not consider in the design until a
customer does something you as the designer didn't anticipate. There
are always design elements in a chip that you don't reveal in the
datasheet. As a chip designer, I am always hesitant to roll my own
for stuff I build for myself. There is a lot of screw up derived
knowledge in every chip.

LDOs are funny things. Too much gain can be a problem. Generally a
single gain stage works best since you have to deal with pole shifting
due to the external load. So beware of using multistage op amps in
such circuits.

Wouldn't you just pick a voltage and linear regulate to it? The
trouble with your sensing scheme is it will need to take into account
spikes on the supply due to load variations. While you are thinking of
a feedforward design, there is feedback from the load variance to
consider.

Hi,

Our long-time PADS guy left to start a new life, and we're breaking in
a replacement.

It's going well, except for this annoyance: we used an old board as
the basis for a new one, with a big ECO, saving the outline, mounting
holes, and most of the power supply stuff. Works fine, renamed and
saved as a new design. But the fab and assembly drawings still show
the old design name at the lower-left, and we can't find the menu item
that might allow us to change this. The PADS docs and HELP are of
course no help.

We're running Logic and PCB version 5.0.

This isn't a problem in schematic printouts, since there the design
name comes out as a pleasing string of heiroglyphics.

Help appreciated.

John

This would be a good question to post on the PADS forum, but I think you
can change the name of the design when you "Run" the "Print/Plot" menu, and
there is a little text box for job name.

Otherwise, you can just export the design to an ASCII file and find the
offending text, change it, and ASCII import back in.

I have PADS2004sp2. I think it worked the same with its predecessor, 5.x.

If you had a newer version this might not work. Every time they fixed one
bug, they introduced a few more "features" and a whole sackful of new bugs.

Paul


Thanks: it turns out that you have to save the project and re-open
it... it's that simple. Our new pcb person had kept the job open for
days, without a save-as!

We dropped PADS support at V5. Pads 5 is essentially perfect, so all
Mentor could do is break it. When they started offering courses to
help experienced Logic users to use the new rev of Logic, we figured
it was time to bail.

John


I can still hear the echoes of the save early and often lecture you

It's The Brat, and she had to learn PC layout in one week, the only

She's finished one board, a little thing I threw together as a
practice project she could get done before he left. It's a gain-100,
DC- 1.5 GHz amplifier in a little box, with some hooks for use as a
photodiode amp and maybe an active signal pickoff. We're sending it
out for board fab today; if it works maybe we'll press release it as a

Can you dance around their klutzy frame and title block by ignoring
them and putting your own smaller frame inside their frame, and then
running some postscript postprocessing to crop down to what you want?


That's what I want to try next because it seems there is no interest in
the gEDA community to look at the power pin issue and none in the Kicad
community to look at the frame thing. I'd love to write corrected code
myself by I am not a programmer. Being a hardware guy it's tough to
figure out PS postprocessing, could use some more mainstream file format
and do a crop by hand. Won't be very precise though.

If I have my druthers I'll fire up the old OrCad SDT. It was perfect but
didn't do zoom, print and stuff too well in a DOS window. I'll have to
see if it's better in a virtual machine with a clean native DOS on
there. Printing will probably remain an issue.

I still use SDT386+ as my primary schematic tool. With macros and a
keyboard with the function keys on the left side of the keyboard, this
is a very efficient way of designing. SDT386+ and PCB386+ drivers have
been constantly upgraded over the past 12 years outside of Orcad.

The biggest improvement: you don't need a real DOS environment
anymore. SDT & PCB now run in a real window in W2k, XP, and supposedly
Vista. A team effort by two people created video drivers so SDT and
PCB make real Windows graphics calls. One guy wrote VESA drivers in
assembly and another guy recoded in C, then created the GDI drivers.

As for printing, all my schematics are printed out to PDF which makes
them searchable. My work colleague wrote a tricky batch file which
automatically resizes any size drawing to a paper space of your choice
using Ghostscript. I modified an Open Office font which creates text
that closely matches what you see on the screen. To print a schematic
file to PDF is one command line batch file.

If you like printing to laserjet printers, there are drivers available
to do that.

If you need a GIF drawing to paste the schematic in a document, there
are conversion tools available to do that or you can convert your PDF
to bit map.

Want to stack a bunch of pins on top of another? Composer has been
modified to allow that which is useful for FPGA parts with dozens of
power and ground pins. 27 ground pins only require one pin space on
the schematic.

All this can be found on
http://tech.groups.yahoo.com/group/OldDosOrcad/ . There are a bit over
300 members. The files section has new drivers and exe files to
support modern methods. Plus, there are a few dozen people who
actively use SDT and PCB on a daily basis which provide good
information on use and setup of old DOS Orcad.

If your customer wants Capture formated files, Capture imports SDT
files, and does a good job at it if its version 7 or newer.

SDT's back-end processing is so open that you can write your own
netlist formaters which we have done to support our PCB tools. The
intermediate ASCII netlist file that SDT spits out can be converted to
a netlist format of your liking.

All of the country's problems would fix themselves if they simply

Constitutional levels.

To pay back the Soc. Sec. and Medicare scams, use an OUTGO tax - i.e.,
tax what people SPEND.

That is already taxed at the state level (in most states) Do you want to
add a Federal tax to that (even at the hope of eliminating personal income
tax, it would be very high ~ 20%).

will take same serious placement and routing changes to fix.

(THS3201 current-mode opamps... 1.8 GHz, 10v/ns. Joerg will lecture me
fer sure.)

Pure ipa tends to leave white crud when used to remove flux, hence the
additives.

I thought the white crud left behind was the "acid salts" from the flux
and
that the alcohol as a non-polar solvent dissolved the rosin but not the
salts. I thought a polar solvent (like water) was needed to get rid of the
salts - or is acetone or mentha-1,8-diene polar?

20 mpg is economical ?

The fully loaded suburban is like an SUV, with 4WD. The Crown Vic. is
another matter.

However, when I look at the
recall history for the Grand Marquis I get the goose bumps:

On my Mitsubishi there was exactly one (1!) alert in > 10 years. It was
a very minor thing, they only had to check whether a copper tubing was
far enough from a fender cut-out. Which it was on mine. The mechanic
said they were instructed to check that on every one that came in and he
hadn't seen a need to bend it on any of them. Heck, I didn't even have a
light bulb blow out in over 10 years that I owned it.

Smaller US cars is something I am cured of for good. I had a Horizon for
many years. Never again. It barely made it past the 6-years rust-through
warranty and then the rear right suspension crushed through and showed
up in the passenger compartment. That could have resulted in a serious
wreck because it jams the rear wheel.

Have they not heard of galavanised steel ? Saabs simply don't rust on account of that.
Hence the one that did a million miles (on the original engine too). And it had wiped
out quite a few moose in its time too.
