This connection is required since it brings the sampled signal from the 568 to the 230. | |||
The 230 does not control the 568. | |||
The 568 sends signals and the 230 displays them on the [[Nixie tube]] readout | |||
and generates control signals on its rear panel connectors. | |||
One exception to this is the CRT intensifier signal, which is sent by the 230 to the 568. | |||
This signal intensifies the trace in the various zones, | |||
which are configured on the 230 or remotely using a [[241|241 programmer]]. | |||

The power supply in the Tektronix 230 is linear and provides regulated of +50 V, +12 V, +3.8 V, +1.75 V, | |||
−3.5 V, and −50 V. It also provides a +255 V unregulated output. The power supply transformer, electrolytic | |||
capacitors, and output transistors are part of the chassis, not a removable unit. The regulator circuits are on a circuit card. | |||
