Air cleanliness level3 Terms and definitionsThe following terms and definitions apply to this document. 3.1 Coaxial switch The high-frequency interface is the microwave switch of the coaxial connector. 3.2 Waveguide switch The high-frequency interface is a microwave switch of a waveguide. 3.3 Action voltage pick-upvoltage The minimum voltage required for a microwave switch to switch from one state to another. 3.4 Operating voltage Within the scope of the specified working environment, ensure the microwave switch can normally switch the voltage range. 3.5 Switching time When the microwave switch is switched, the time required from receiving the excitation signal to the microwave switch switching and stabilizing to the target state. Note. For coaxial microwave switches, the switching time includes reed spring time, and for waveguide microwave switches, the switching time includes rotor jitter time. 3.6 Command interference sensitivity ripplesensitivity When there is some interference in the excitation circuit of the system, the microwave switch does not have the ability to malfunction. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 38771-2020_English be delivered?Answer: Upon your order, we will start to translate GB/T 38771-2020_English as soon as possible, and keep you informed of the progress.
