The UBBV 1060 Bypass Pre-Amp is a low-noise, pass-through amplifier featuring a full frequency range from 100 MHz to 6 GHz (with capabilities as low as 50 MHz with dB amplification). This battery-powered Bypass Pre-Amplifier works with any brand of spectrum analyzer, and fits directly to AaroniaUSA Spectran Spectrum Analyzers, to provide a broadband sensitivity increase of up to 23 dB. This model of pre-amp features internal switching, allowing the device to handle both high and low signals, by bypassing the LNA when large signals are present. Users can easily change the operation mode from standard to bypass with the push of a button. UBBV Pre-amps can be operated via internal battery (running time approx. 3-4 hours) or via the included AC adapter.
