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]]. | |||
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]]). The 514 provides DC response ''and'' 10 MHz bandwidth. | |||
The 514 uses a [[5CPA]] CRT with a total accelerating voltage of 3 kV (−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 27 V/cm vertical and 32 V/cm horizontal. | |||
The power supply is regulated based on a −140 V reference produced by an [[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. | |||
''(There were also some models marked 'Series A', which may have been a predecessor to the 514A? How does the 514AD differ from the 514D?)'' | |||
It has no [[thermal cutoff]]. | It has no [[thermal cutoff]]. | ||
