The 502 is a dual-beam oscilloscope [[introduced in 1958]]

The 502 is a dual-beam oscilloscope [[introduced in 1958]],

~~with a high~~ sensitivity of 100 ~~or 200~~ microvolts/cm,

followed by the 502A in the early 1960's.

~~depending on~~ the ~~mode whether differential inputs are used~~.

Both beams have differential inputs.

At ~~200uV~~/cm the bandwidth is ~~only 100kHz but at 200mV/cm it rises to~~ 1MHz.

When set for maximum sensitivity, the 502A is 100 microvolts/cm

~~There is a 502~~, a 502A, ~~and an RM502A~~.

and has a vertical bandwidth of 50 kHz.

There is a transistor-regulated heater supply ~~build~~ in.

At lower sensitivity settings the bandwidth increases.

At 200 mV/cm the bandwidth is 1MHz.

At 100 mV/cm and 1 kHz, the common-mode rejection ratio of the 502A is 40,000:1.

There is a transistor-regulated 6.2V DC heater supply for the tubes in the

first stage differential amplifier.

This heater supply uses the -150 V supply as its reference.

The -150 V supply uses a [[5651]] voltage reference tube as its reference.

There is no post-deflection acceleration.

The CRT cathode voltage is -2900V.

~~Price at~~ July 1959 was $825.

There is a 502, a 502A, and a rack-mount model, the RM502A.

The price of the 502 in July 1959 was $825.

Mod 104 on a 502 provides single sweep lockout.
