Keysight / Agilent 85685A Overview
The Agilent 85685A RF preselctor is designed to operate with the Agilent 8566B and 8568B spectrum analyzers. The RF preselector adds tracking filters to reduce overloading from out-of-band signal and preamplifiers for improved system sensitivity over the 20 Hz to 2 GHz frequency range. The Agilent 85685A RF preselector has two input, 20 Hz to 50 MHz and 20 MHz to 2 GHz. There is also a bypass mode which is DC to 18 GHz. Input 1 has a built-in transient limiter for protection from transients generated by line impedance stabilization networks (LISN). The preselector is fully programmable over the HP-IB (IEEE-488).
Features:
- Operates with the Agilent 8566B and 8568B spectrum analyzers
- Reduces overloading from out-of-band signal
