Hi Dave
I'm not familiar with the 561. Although, the Nicolet doesn't have enough
dot storage to do X/Y well, It is handy to use the digital scale magnification
to set things like intergrator drift or balancing Sine/Cosine oscillators for
zero gain/loss. The 561 is a persistance(sp?) scope as I recall and
should be a nice complement to the digital scope.
I'm glad you didn't drive all that way
for an EC-1.
Yes. :) I'd love an EC-1, but they're much easier to ship than an H-1.
You'll most likely want to aquire a couple
other pieces.
A XY plotter and a XY storage scope.
I have a HP 7044 to plot with and a Nicolet oscilloscope 2090 w/ 206 front end.
These come in real handy.
I am swimming in oscilloscopes. Seriously, I think I have over
thirty oscilloscopes now. I think I have a problem. ;) I have a few
Nicolet digitizing scopes, and I have a nice Tek RM561A that should be a
nice fit for the H-1 in repetitive mode.
With the H-1, I got a Heath IR-18M chart recorder. It's not
functional; I've gotta find schematics for it and see what's up. Though
it's mechanically free, the pen carriage won't move at all under
electronic control.
It is most likely the final driver circuit or the motor that runs the pen.
If it is the motor, before giving up, check the brushes.
I have an HP 7090A plotter (wonderful device by the way, have you
seen it?) that will be nice to use with this. I'd really like to find
one of the ancient pure analog X/Y plotters from HP to run the H-1 into.
Watch for the 7044's on ebay. They come up every now and then.
They are considered ( for there time ) to be high speed. It just
is right on the edge for slow simulations for speed. A slower
plotter would not be a practical.
