70908A RF Section, 100 Hz to 22 GHz 主要技術規格 Fundamental mixing provides 100 Hz to 22 GHz broadband input conversion Achieves unprecedented sensitivity for microwave measurements and for high-speed lightwave modulation rates Dynamically-tracked preselector provides superior amplitude accuracy without preselector peaking Excellent dynamic range Contains a 70 dB step attenuator variable in 10 dB steps, Option H25 provides a 5 dB step attenuator 敘述 The 70908A RF section provides fundamentally mixed 100 Hz to 22 GHz broadband input conversion for the 71210C spectrum analyzer and the 71400C lightwave signal analyzer. Fundamental mixing provides a means of achieving unprecedented sensitivity for microwave measurements and for high speed lightwave modulation rates. This sensitivity allows you to reduce microwave spurious test times from days to hours. Improved sensitivity also improves second and third order dynamic range. Excellent dynamic range is obtained with an analyzer with both good s
