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~~.

Using a three-section [[distributed amplifier]], it provides frequency response from DC to 10 MHz.

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]]).

''or'' an instrument with DC response (the [[512]]). The 514 provides DC response ''and'' 10 MHz bandwidth.

~~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

(-1.5 kV on the CRT cathode and +1.5 kV on the CRT anode) .

The standard [[phosphor]] for a 514 was P1.

The deflection sensitivity of the CRT is approximately

The deflection sensitivity of the CRT is approximately 27 V/cm vertical and 32 V/cm horizontal.

27 V/cm vertical and 32 V/cm horizontal.

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

The +225 V supply uses three [[5V4G]] rectifier tubes in parallel.

Throughout its production run, a 'D' variant was available (514D, with the 'D' being stamped in by hand on some models) which has a 24-section 250 ns lumped L-C [[delay line]].

There was also an 'A' version (514-A & 514-AD respectively), which appears to have been available in 1954.

It has no [[thermal cutoff]].
