502
The 502 is a dual-beam oscilloscope introduced in 1958 with a high sensitivity of 100 or 200 microvolts/cm, depending on the mode whether differential inputs are used. At 200uV/cm the bandwidth is only 100kHz but at 200mV/cm it rises to 1MHz. There is a 502, a 502A, and an RM502A. There is a transistor-regulated heater supply build in. There is no post-deflection acceleration. The CRT cathode voltage is -2900V.
Price at July 1959 was $825.
Mod 104 on a 502 provides single sweep lockout.
