1. Steuerleistung: Steuern Sie die Ausgangsleistung des lokalen Oszillators im Mikrowellen-Überlagerungsempfänger, um die beste Rauschzahl und den besten Frequenzumwandlungsverlust zu erzielen, um den besten Empfangseffekt zu erzielen, und realisieren Sie eine automatische Verstärkungsregelung, um den Dynamikbereich im Mikrowellenempfänger zu erhöhen.
2. Relative standard: as a relative standard for comparing power levels.
3. Attenuator used for radar anti-jamming: it is a variable attenuator that can attenuate attenuation. No attenuation is introduced, and when external interference is encountered, the attenuation increases suddenly.
This is related to the source of the device itself. The difference is that the attenuation of the liquid crystal is irreversible. For liquid crystal devices, we don't have many ways to adjust the color, but its attenuation does not happen often; the color difference of DLP is largely due to the long-term use of the bulb. The easiest way is to adjust it by changing the bulb.
