The Tektronix 7A24 is a high-performance, wide-band, dual-trace amplifier which provides 400 MHz bandwidth in the 7100 Series mainframes.  Bandwidth is constant over the entire range of deflection sensitivities from 5 mV/div to 1 V/div.  Input impedance is 50 OHM.  The 7A24 features five operating modes, trigger source selectability and trace-identify.

The Tektronix 7A26 is a dual-trace amplifier which provides a bandwidth of 200 MHz in the 7900 and 7100 Series mainframes.  Bandwidth is constant over the entire range of deflection sensitivities of 5 mV/div to 5 V/div.  Bandwidth may be limited to 20 MHz to reduce displayed noise in lower-frequency applications.  It can also be used in any of the other 7000 Seires mainframes but bandwidth will be limited to the bandwidth of the mainframe.  The 7A26 features five operating modes, trigger source selectablity and trace-identify.     

Hewlett Packard model 7B80 is designed to work in the TEK 700 Series of mainframes.  It features triggering to 400 MHz, Variable Trigger Holdoff, Peak-to-Peak Auto Triggering.  1 nS to 5 S/div with 1.5% accuracy.

The Tektronix 7B85 is a horizontal timebase designed for use in 7700, 7800 and 7900 Series Oscilloscope  mainframes to provide optimum bandwidth/sweep-speed compatibility. It can also be used in any slower  7000 Series mainframe with some reduction in sweep accuracy at the fastest sweep. It features:
