• tektronix 7844 is a 400 mhz dual beam oscilloscope mainframe, true dual beam oscilloscope mainframe can be set up for a variety of difficult measurments. features pulsed graticule and pulsed crt readout.

• 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 se-lectability, 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 7b80 delayed time base plug-in is recommended for use with 7700, 7800, and 7900 mainframes to provide optimum bandwidth / sweep-speed compatibility, but may also be used in any slower 7000-series mainframe. • calibrated time base: 1 ns to 5 s/div with 1.5% accuracy (50 ns to 0.5 s/div) • triggering to 400mhz • variable trigger holdoff • peak-to-peak auto triggering

• 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).
