Hi all, first post here.
I'm looking to set up a TM 5000 series mainframe and trying to sort out the compatibility gotchas before I "pull the trigger" on one of these.
My main interest is in the differential amplifier plugins. I do mostly audio work and these are the ones I am thinking about:
Question #1) Will the AM502 work in a 5000 series mainframe? (there seems to be conflicting information about whether or not 500 series plugins work in 5000 series mainframes)
Question #2) If I get a 5000 series mainframe with Option 2 (w/ the BNC connector panel on the back of the unit), would I be able to wire from an A5xx plugin's single ended output to a BNC connector on the back panel, and then connect this to a standard o-scope input?
My understanding is that Tek 5000 series scopes' baseline sensitivity is 10 mV/division, so I'm assuming I can set my scope to 10 mV/division, hook up the BNC out (wired to the A5xx plugin's output) from the back of the TM 5000 series mainframe and just plug it into my scope. Does this sound right?
I really appreciate any advice you have about this.
You have some conflicting terms.
The 5Axx modules are 5000 series oscilloscope amplifier plugins. They are
not compatible with the TM500/TM5000 series mainframes.
The AM502 is a TM500 plugin. It is not compatible with the 5000 series
oscilloscopes. Some TM500 plugins are not compatible with the TM5000 series
because of power supply issues. There are only a couple of these and they
are listed in the manuals for the TM5000 series mainframes. Most of the
TM5000 series plugins are not compatible with the TM500 series mainframes,
but there are some exceptions to this as well.
For a given TM500/TM5000 plug-in, the manual will have a section on the
rear interface connections. Any connection listed there can be wired to a
rear panel BNC or Dsub connector on the Option 02/Option 12 mainframes.
Sometimes you must move an internal jumper in the plug-in to route the
signal to the rear interface instead of the front panel. It's all in the

I don't think so. Not sure what the BNC on the back is, but it's
likely an output. Your TM5000 plugins DO NOT EVER fit into a 5000
series scope mainframe THEY ONLY FIT INTO A TM5000 SERIES RACK.
The 5Axx and 5Bxx are vertical and horizontal plugins, which while
they LOOK as if they should plug into a TM5000 series rack, DO NOT.
AND in addition the DC5010, the DM5010, the PS 5010, etc TM5000 units
DO NOT plug into an oscilloscope frame.
Seriously. They have the same pitch (spacing) connectors, but there's
a very specific key (piece of plastic inbetween the connectors) that
is different so you CANNOT plug into the wrong frame. Just don't even
try.... The voltages are WAY different, for one.
I'd say that you'd have to see how the TM5000 is wired, have the
TM5000 plugin in the right slot (the back panel stuff is hard wired to
a particular slot if wired at all), and then see what the output is.
You're likely to be happier taking a front panel output over to the
scope. Reading manuals will give you the details (which I do not
know). Both of my 5000 series scopes need work, and the TM5000's I
have I don't think I bothered to use the BNC's on the rear. DOn't
have the AM503, anyway.
You got it. Please pay particular attention to the capital letters
(yes, either shouting or used as emphasis), because I think the points
made are rather important. Never heard anyone manage to mix the two
TM5000 was an upgrade to the TM500 series of plugin. Generally added
a microprocessor, an IEEE488 (HPIB) interface, local remote control of
the module and a relatively smart (pushbuttons not mechanical
switches) front panel interface.
Because of *some* similarities, the TM500 series of plugins (generally
older, no microprocessor, no remote, mechanical switches) *could* be
used in the TM5000 series frames, but there was never a remote
The 5000 series of oscilloscope was a 1 mhz/50 mhz (varied) maximum
bandwidth oscilloscope intended as a lower cost option for mostly
medical electronics, unless you needed 50 mhz bandwidth (see the 54xx)
series and appropriate plugins).
Ah kay. Thanks for explaining. So, looking at the pinout in the 5A22 schematics, sure enough, it's totally different from the TM5000's receptacle wiring.
I guess it would be kind of tedious, but it seems like a DIY frame/chassis to house and power these 5Axx plugins could be constructed with the correctly keyed edge connector.
Oh well, thanks for the info! You saved me a lot of trouble. :)
