DE EMPHASISED BASE BAND VIDEO 1V p–p
VIDEO ANALYSER ROHDE & SCHWARZ UAF
The video drive characteristics measurements were made using the above test configuration. The maximum figures recorded in the Electrical Characteristics Table coincide with high temperatures and extremes of supply voltage. No adjustment to the recorded figures has been made to compensate for the effects of temperature on the external components of the application test board, in particular the varactor diodes. If operation of the device at high ambient temperatures is envisaged then attention to temperature compensation of the external circuitry will result in performance figures closer to the stated typical figures.
