The Lavoie LA-265-B is an unauthorized clone of the Tektronix B 20 MHz amplifier plug-in for 500-series scopes, made by Lavoie Laboratories for a defense contract.

Specifications

  • Deflection factor: 0.05 v/cm to 50 V/div DC-coupled, 0.005 v/cm to 50 V/div AC-coupled
  • Signal inputs: Two signal inputs with more than 60-dB isolation
  • Step attenuator: 12 calibrated steps are provided: 0.005, 0.01, 0.02, 0.05, 0.1, 0.2, 0.5, 1, 2, 5, 10, and 20 V/div
  • Accuracy: Within ±3% of indicated deflection in calibrated position
  • Maximum input voltage: 600 v (dc plus peak ac)
  • Risetime: 18 nanoseconds in a 545
  • Frequency response: DC to 20 MHz in a 545

Note: Full frequency response is available with deflection sensitivity between 0.05 and 20v/cm. In more sensitive positions, the input is DC-coupled and slightly slower.
