Hi, hope you young pups can teach an old dog new tricks
I have a Motorola same as R2001D or R2008D "communications systems analyzer" commonly known as a "service monitor" While still usable in the shop, the CRT is getting dim. These CRTs are proprietary, were available only from Motorola at great cost, and were evidently only manufactured by either Telefunken or Magnavox, and sold only to Motorola under Motorola part numbers. They are no longer available, unless you score, say, a parts unit on th' Bay
I guess my question is twofold:
A.....how can I find a more common CRT substitute, perhaps with circuit changes, and
B....Is there a flat panel device I can sub, even if it must be outboard?
It seems to be difficult to find a substitute, first, physical limitations, and many OTHER tubes such as Tektronix seem to also be proprietary, so finding specs for THEM it tough.
This is fairly common as analog CRTs go......intensity input (z) for character and other special video display, and common X-Y amps for vertical / horiz. functions.
So things like these there new fangled digi scopes, none I have found have a Z (intensity modulation) input.
Anybody have ideas on a work around for this?
If any of you have ideas, I did remove and measure the CRT size, and have some of the circuit voltages. Motorola is sparing about this in their service manual.
Thanks for yer help
