  • Bandwidth : DC to 200 MHz
  • Calibrated 5 mV/div to 5 V/div in 10 steps
  • Input Impedance : 1MegOhm 2%, 20pf


  • The 1979 catalog lists the following recommended probes for the 7A26:
    Passive : P6009, P6013A, P6015, P6063B, P6101, P6106
    Active : P6201, P6202
    Current : P6022, P6302/AM503, P6303/AM503

    The 7A26 200MHz Amplifier Plug-In is a dual trace plug-in which 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 over the entire range. Also include a 20MHz bandwidth limit switch which reduces noise in lower-frequency applications.


    The 7a26 , a dual trace pluggin amplifier, is the basic building block for three or four trace operation . It features constant bandwidth for all deflection factors. It has 5 operating modes : CH1, CH2, ALT, CHOP, ADD) trigger source selection (Ch1, CH2, Mode.)

    Bandwidth may be set at full or limited to 20Mhz.
