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
10MHz bandwidth (the [[511]]) or an instrument with DC response (the [[512]]).
The 514 provides DC response and 10MHz bandwidth.  It weighs 60 pounds and
consumes 360 watts.  The 514 uses a [[5CPA]] CRT with a total accelerating
voltage of 3000 volts.  The deflection sensitivity of the CRT is approximately
27V/cm vertical and 32V/cm horizontal.


The power supply is regulated based on a -140V reference produced by a [[OD3]]
