Greetings Everybody, My son brought by today an old oscilloscope. The Brand is Lambda and the model is MM-2. On the back are three pairs of terminals. One is marked with G & V, one G & H, and the last pair R & S. So the first two pairs are pretty obvious, horizontal and vertical, but I don't have any idea what the last pair is for. The screen is about 2 inches in diameter, and is marked with painted on lines. Two lines, one above the screen center and the other below are marked carrier frequency. Removing the cover shows "NAVY" printed on the side of the CRT. This link:

shows the device. From the web I gather this is a modulation monitor. I think it was rack mounted. Anyway, it would be neat if he could connect the thing to some sort of signal so that it would show more than a stationary dot on the screen. I can buy a manual for 25 bucks but I'm not that curious about this primitive 'scope. So, any suggestions? Anybody got one of these? Or a manual that you would be willing to scan and email? Thanks, Eric
