The Tektronix Type 533 is a 15 MHz oscilloscope introduced in 1958
that uses letter-series and 1-series plug-ins.
It is similar to a 535, but without the second, delayed timebase. Instead, it has a range of horizontal magnifiers from ×2 to ×100.
There is also a rack-mount version, the RM33.
Later 533A have BNC connectors.
Specifications
The standard CRT for the 533 and 533A is the T5330-2. It has 10 kV accelerating voltage, consumes 500 watts, and weighs 62 pounds. please add
Internals
The vertical amplifier consists of a 12BY7 differential amplifier followed by a 6DJ8 cathode-follower, followed by a 6197 differential (common-cathode) output stage that drives the 200 ns L-C delay line, which drives the vertical deflection plates of the CRT.
Trigger pickoff is taken after the cathode follower stage in the vertical amplifier. There is a 6DJ8 differential trigger pickoff amplifier followed by half of a 6DJ8 a cathode follower, buffering the trigger signal.
The trigger circuit is a 6DJ8 trigger amplifier followed by a 6DJ8 Schmitt trigger. Triggering can be from the internal pickoff or from an external signal or "line" trigger, from a 6.3 V tap on the power transformer.
The 533 contains a 128F thermal cutoff. The high voltages for the CRT, +8650 V and -1350 V, are generated by a 60 kHz Hartley power oscillator and five 5642 high-voltage rectifier diode tubes.
