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 5 mV/div (AC) / 50 mV/div (DC) to 20 V/div, 1−2−5, and variable ×2.5 (up to 50 V/div)
Inputs Two signal inputs with more than 60 dB isolation
Accuracy Within ±3% of indicated deflection in calibrated position
Maximum input 600 V DC + peak AC
Rise time 15 ns (18 ns in a 545), 25 ns in 5 mV/div to 20 mV/div ranges
Bandwidth DC to 20 MHz in a 545

Note: Full frequency response is available with deflection sensitivity between 50 mV/div and 20 V/div. In more sensitive positions, the input is AC-coupled and slightly slower.
