Preselectors Other Types of Equipment : Agilent-Keysight 8445A/002

The 8445A Tracking Preselector contains a YIG filter which tracks the tuned frequency of the analyzer over the range of 1.8 to 18 GHz. The preselector suppresses the image and multiple responses which result from harmonic mixing. The YIG filter is electronically tuned by sweep voltage and band code signals from the analyzer. Tracking filter 3 dB bandwidth is typically 30 to 45 MHz. Tracking filter skirt roll-off is characteristic of a two pole filter. Insertion Loss for the low-pass filter (DC to 1.8 GHz) is <2.5 dB. Insertion loss for the tracking filter (1.8 to 12 GHz) is <7 dB and (12 to 18 GHz) <10 dB.
