TEKTRONIX 7934 ANALOG CRT STORAGE MAINFRAME HAS A BANDWIDTH OF DC-500 MHz, Tektronix's highest bandwidth analog storage mainframe.

The 7A19 Plug-in Amplifier has a maximum bandwidth of 600MHz and calibrated deflection factors of 10 mV to 1 V/div with an accuracy of ±3%. 50-ohm input impedance and normal or inverted display.  This unit includes option 04 Variable Delay Line.

The 7A26 Amplifier Plug-In is one of the most popular plug-ins used today for the 7000-Series Oscilloscope Mainframes. This dual trace plug-in offers 5 operating modes, trigger-source selectability, and trace identify. Vertical sensitivity of 5 mV/div to 5 V/div and with appropriate mainframe, DC to 200MHz bandwidth is maintained constant over the entire range. Other features include a 20MHz bandwidth limit switch which reduces noise in lower-frequency applications.

The 7D15 Universal Counter / Timer Plug-In is designed for use in all 7000-Series oscilloscope mainframes having CRT readout. The unit can be completely controlled by the oscilloscope's delayed gate. Arming inputs are provided for each channel.
Frequency Mode: DC to 225MHz, resolution is 0.1Hz
Period and Multi-Period Mode: 10 ns to 10E+05 s with selected averaging of 1 to 1000 events in decade steps, 10 ps max resolution
Time Interval (TI) and TI Average Mode: 6 ns to 10 s with selected averaging times of 1 to 1000 in decade steps, 0.1 ns resolution
Frequency Ratio, CH B/Ext. Clock: 10E-07 to 10E+04
Manual Stop Watch: 0 to 10E+05 s
Totalize, CH B: 0 to 10E+08 counts

The 7B92A Dual Time Base Plug-In provides a 0.5 ns/div to 0.2 s/div calibrated time base. The unit has triggering to 500MHz, alternate display of Intensified Delaying and Delayed Sweeps, and Int/Ext/Ext÷10/Line triggering capabilities (main and delay external triggering). The 7B92A is recommended to be used only in the 7800 and 7900 Series Mainframes. The unit also may be used is all other mainframes at slower sweep speeds.
