Features:
- Auto Preselector
- Frequency range: dc-1.8 GHz low-pass filter, 1.8-18 GHz tracking filter
- Tracking filter 3 dB bandwidth: typically 20-45 MHz
The Agilent 8445B Tracking Preselector contains a YIG filter which tracks the tuned frequency of the analyzer over the range of 1.8 to 18GHz. The preselector suppresses the image and multiple responses which result from harmonic mixing.
The preselector can also reduce distortion and increase dynamic range when signal separation exceeds the preselector bandwidth. For tuned frequencies below 1.8 GHz, a low pass filter prevents image and multiple responses. An optional LED display provides a readout of marker frequency with 1 MHz resolution.
