The 7104 makes extensive use of custom integrated circuits and hybrid circuits, inter alia, the [[155-0174-00]] Delay Line Compensator, [[155-0173-00]] Vertical Channel Switch, [[155-0176-00]] Vertical Output Amplifier, [[155-0194-00]]/01/02/03 CRT Termination, [[155-0175-00]] Trigger Amplifier, [[155-0178-00]] Horizontal Output Amplifier, [[155-0012-00]] Z-Axis controller/amplifier, and [[155-0067-02]] SMPS controller. The high-speed amplifiers use [[Hypcon]] ceramic packages that use elastomer-based frames for coupling chip connections to the circuit board at constant impedance. The signal connections are differential throughout, and the signal path was optimized for matching and low reflection, including the plugin to mainframe card-edge connectors and the use of stripline and coplanar waveguide techniques right up to the CRT. | The 7104 makes extensive use of custom integrated circuits and hybrid circuits, inter alia, the [[155-0174-00]] Delay Line Compensator, [[155-0173-00]] Vertical Channel Switch, [[155-0176-00]] Vertical Output Amplifier, [[155-0194-00]]/01/02/03 CRT Termination, [[155-0175-00]] Trigger Amplifier, [[155-0178-00]] Horizontal Output Amplifier, [[155-0012-00]] Z-Axis controller/amplifier, and [[155-0067-02]] SMPS controller.

The 7104's amplifiers use a then novel scheme of "feed-beside" compensation ([ | The 7104's amplifiers use a then novel scheme of "feed-beside" compensation ([[Patent US 4132958A]]) where instead of matching the HF response to the LF response, the LF response is determined by off-the-shelf operational amplifiers in parallel to the high-speed amplifiers, with a number of adjustable R-C time constants to compensate for thermal and other LF effects. The same technique is employed in the [[7A29]] amplifier plug-in. | ||
