The '''Tektronix 7B81P''' is a programmable time base plug-in for [[7000-series scopes]] that was probably designed in 1975. | |||
It is composed of a digital board, a trigger board, and a sweep board. | |||
On the digital board, there is a [[Motorola 6800]] microprocessor and six 6820 Peripheral Interface Adapter ICs to provide more I/O pins. | |||
On the trigger board, there is a [[155-0126-00]], a [[155-0109-00]], two AD7511 analog switch ICs, an MC1408 DAC, a CD4053 analog switch, and a couple of opamps. | |||
The sweep board is mostly discrete and makes use of Tek-made timebase capacitors. | |||
