Updated November 2008. I was recently shown the link to a manual for this scope at Look for the.
Here we have a 180 TR (fitted with long persistence CRT) over a 180A on the left and a AN/USM 281 (180F I think) on the right. These are excellent and accurate scopes based on a 100MHz mainframe having an internally illuminated graticule. A precision wide-band X amplifier is included in the mainframe while the Y plates connect directly to the Y plug in. Most of the issues that arise with these scopes are mechanical, aged solder joints, dirty switches, loose switch nuts and various screws. I do sometimes experience component failures, the local decoupling capacitors in the timebases are especially likely to fail. 99 Ways To Cut Sew Trim And Tie Your T-shirt.
Occasionally a transistor will fail, the solution is to logically isolate the circuit that has failed and take transistors out and test them until the culprit is found. In general, all the Y plug-in faults I have had are mechanical while the time bases are more likely to suffer component failure. They represent the first generation of solid state after the vacuum tube era and date from circa 1970. I have read that the 180 “T” series displays are recommended for use with the 8755B network analyser. They provide zero offset recorder outputs, and both positive and negative 5-volt retrace blanking inputs.
The Y plug ins I have are all dual channel general purpose 50MHz types with delay lines, the 1801A in the 180TR and 180A having a sensitivity of 5mv/cm to 20v/cm while the PL1186A in the 180F has a x5 switch that increases the sensitivity to 1mv/cm. One of the 1801A units has power connectors that provide +15v and -12.6v for active probes, I must try to obtain at least one of these probes! This unit appears to be a very early example, the internal configuration is quite a bit different to the other unit though they both bear the same model designation. A rather confusing point is that there is a screened wire that connects from the interface plug (between the time-base and the Y unit) to – nowhere! I can find no evidence under a magnifying glass that it was ever connected and the locations on the plug end are not used on the time-base side of any units I possess. These locations (14 & 15) are not assigned in the manual either. It appears to be completely redundant yet, is clearly an original part of the wiring loom.
