An optional component, the [[P7001]] Processing Unit, can be added to a 7704A between the acquisition unit and the display unit. The Acquisition Unit of the 7704A, the P7001 Processor, and the Display Unit of the 7704A are connected by the Acquisition-Processor-Display (APD) Interface shown below. | An optional component, the [[P7001]] Processing Unit, can be added to a 7704A between the acquisition unit and the display unit.

The vertical amplifier in the 7704A uses the [[155-0077-00]] hybrid. | |||
The 7704A SMPS uses a custom Tek chip ([[155-0067-02]]) to implement the control functions. Since the SMPS is a kind of oscillator, there is the issue of how it will start when it is first powered up. Early 7704As use a diac in the starter circuit. Later 7704As use a unijunction transistor in the starter circuit. | |||
