Never to be used GPIB option and power consumption and heat.


Lawrance A. Schneider
 

My 2465BDM has a GPIB option. I'll never use it; all my other instruments either have no external connection to the world (my computer) or use ethernet.

Relative to heat and energy consumption would it be advantageous to remove the card?

Thanks, larry

I have this option on my 2465 - 300 MHZ version and I purchased the cable.
I have plans to get it to work with a computer and I'm looking for someone
who has done this, so I don't need to reinvent something that is done
already! ha ha ha
Can someone point me to the resources I can use?
Is there some modern PC connection available?
Why would you like to remove it?
It isn't hurting anything and the power supply creates almost the same heat
as if you didn't have it, so you wouldn't save any $$, I think.

Thank you all!
Stay safe and have a great weekend!

Percentage-wise, the GPIB power is probably no big deal. I don't know how the GPIB option is connected internally, but if it's say, via a ribbon cable, you may be able to just unplug it and secure it so it can't short to anything. Then make sure the system starts up and runs properly without it - it may cause error reports on POST, for instance, if it expects to find it.

If the GPIB module is hard-plugged directly into a port, and requires physical removal to disconnect, then you'll have to worry about plugging the empty cabinet hole, and the possibility of eventually losing the GPIB parts - this tends to happen when things are separated.

The simplest thing is to just leave it be.

Hey Tony,

The 2465 is an analog scope, and the GPIB is only good for changing or
reading back the settings on the scope. The scope itself has no idea what's
displayed on the CRT, so you wouldn't be able to e.g. read back the
displayed waveform to a computer.
For that you'd need a digitizing scope of some description.

Thank you very much for explaining it to me!
Somewhere I heard that it was possible, but now it is clear to me, thanks
to you Siggi.
Have a great weekend!
Stay safe all of you.

Hi Ed, Hi Lawrence:
It's probably detailed in some thread on the forum already... but page 5-17 of the Tektronix (1990, rev. 1991)24X5B12467B Options Service(Serial Number B050000 and above, 070-6864-02) manual covers the removal. (power cable, internal bus cable, led cable, and cable to the GPIB connector.)

That manual is available on tekwiki at
http://w140.com/tekwiki/wiki/2465B

But unless you plan to take the scope with you (and some of would like to, I know)... posterity may thank you for leaving the GPIB option in... and if you sell it in the future, you may than you for leaving it in.

Best regards and wishes.
Roy

Hello Roy,

Well at 75, the only place I could be taking it is to the grave. However, I was simply thinking about the extra heat and power needed to run the board. I do understand the idea of leaving it for posterity; I guess I will leave it in. Mr. Harris has not entered in as to the power used, but I guess it is minimal.

Thank you, larry
