The Tektronix 514 is a monolithic general-purpose oscilloscope introduced in 1949 or 1950. | |||
It was designed by Tektronix engineers Bob Davis and Dick Rhiger. | It was designed by Tektronix engineers Bob Davis and Dick Rhiger. | ||
Using a three-section distributed [[distributed amplifier]], it provides frequency response from DC to 10MHz. | |||
Prior to the 514, customers had to choose between an instrument with 10 MHz bandwidth (the [[511]]) ''or'' an instrument with DC response (the [[512]]). | |||
The 514 provides DC response ''and'' 10 MHz bandwidth. It weighs 60 pounds (27 kg) and consumes 360 W. The 514 uses a [[5CPA]] CRT with a total accelerating voltage of 3000 V. The deflection sensitivity of the CRT is approximately | |||
27 V/cm vertical and 32 V/cm horizontal. | |||
