Some of the outstanding characteristics of the Preselector are:.
Multiple filters – the Preselector has 7 bandpass filter steps covering the range from 9 kHz to 1000 MHz, and a high-pass filter covering the range from 1000 MHz to 1800 MHz.
Reduced distortion – the Preselector limits potentially distorting input to a spectrum analyzer by attenuating signals outside the frequency range of interest.
Increased broadband dynamic range – the Preselector increases sensitivity to low-level signals by attenuating strong signals outside the frequency range of interest.
Manual or remote operation – you can operate the Preselector using its front-panel controls or a GPIB equipped controller or computer.
Bypass mode – you can remove the Preselector from the testing circuit without disconnecting it.
