The Tektronix 570 was Tek's first curve tracer, introduced in 1955. It is a curve tracer for vacuum tubes. It sweeps the plate voltage between zero and a selectable maximum voltage while "stepping" the control grid through a set of voltages.
A selectable screen voltage is available for testing tubes with screens. The plate voltage is measured and applied to the X-axis of the display. Plate current is measured and amplified and is applied to the Y-axis of the display.
John Kobbe had a key role in the development of both the 570 and 575 curve tracers. He says:
While I was working on the 540 series vertical amplifier, Virgil Briton, whose bench was next to me, had put together a vacuum tube curve tracer using stepping relays and other mechanical devices. I remember thinking that, that was a neat display even if it did a lot clicking and was slow.
After putting the cross hatch generator together, I knew it would be very easy to do the curve tracer electronically, it started for in house use, but after putting a self-contained instrument together, Tek decided to call it 570[1] and sell it.
Key Specifications
- please add
Internals
The 570 contains five transformers:
- T310: center-tapped isolation transformer for plate sweep
- T340: multitap transformer for heater voltages
- T401: multitap autotransformer for selecting peak plate voltage, feeds T310
- T501: transformer for floating supplies and screen voltage supply
- T620: transformer for 60 kHz HV power oscillator for CRT voltages
The screen supply is regulated and uses a 6CD6GA tube as the series regulator.
The vertical and horizontal amplifiers are almost identical. The first stage is a differential amplifier made of two 6AU6 tubes. The second stage is a differential amplifier made of both halves of a 6BQ7A.
A T52P1 CRT is standard in the 570.
