The Tektronix 454 is a 150 MHz portable dual-trace scope introduced in March 1967. It can be seen as an improved 453. The successor 454A was introduced in 1971.

Manuals

The 454 is the fastest general-purpose Tektronix scope that does not use proprietary hybrid or integrated circuits. It uses a CRT with distributed vertical deflection plates.

Key Specifications

Bandwidth 150 MHz (454: 100 MHz @ 10 mV/div, 60 MHz @ 5 mV/div; 454A: 100 MHz @ 5 mV/div, 50 MHz @ 2 mV/div)
Deflection 5 mV/div to 10 V/div; 1−2−5; 454A: additional 2 mV/div
Sweep 50 ns/div (454A: 20 ns/div) to 5 s/div (1−2−5) plus ×10 magnifier, and variable; timebase B to 50 ms/div
CRT T4540, P31 phosphor standard / P11 optional; +12/–1.96 kV acceleration
Weight 13 kg / 29 lb
Power 90–136/180−272 V, 48−440 Hz, 100–145 W

It is possible to cascade the CH1/CH2 input amplifiers to obtain a sensitivity of 1 mV/Div (454A: 400 μV/div) at a bandwidth of 33 MHz.

The 454 has two ±12 V probe power outputs for P6045 probes.

Internals

The 454 has a 140 ns delay line in the signal path after the input channel switching and before the main vertical amplifier. There is a phase equalizer after the delay line to mitigate the harm done to pulse fidelity by the delay line.

454 Modifications

The 454 came in several different modifications that were indicated on the field on the front plate directly below the "454" lettering, left of the serial number field. Known modifications are

  • MOD163D
  • MOD210N - P6047 accessory probes come in 6 ft variant with extra accessories.
