LEEM-16 Dielectric Constant Apparatus

Iinkcukacha zeMveliso

Imixholo ephambili yovavanyo

1. umlinganiselo wemvume yevacuum e0 kunye nemvumelwano enxulumeneyo;

2. ukufunda i-LC resonance method ukulinganisa i-capacitance encinci;

3. ukufunda ukusetyenziswa kwe-oscilloscope yedijithali.

Iiparamitha eziphambili zobugcisa

Deumbhalo	Iinkcukacha
Ijenereyitha yomqondiso weDDS	I-4.3 intshi ye-LCD ukubonisa, i-sine wave kunye ne-square wave frequency 1μhz ~ 10mhz, i-amplitude yesignali 0 ~ 10vp-p, i-waveform signal offset kunye nesigaba sinokusetwa, kusetyenziswa izitshixo zedijithali kunye nokutshintsha ikhowudi yokulungelelanisa.
Isixhasi esisemgangathweni	R1 = 1kω, ukuchaneka 0.5%.r2 = 30kω, ukuchaneka 0.1%
Inductor esemgangathweni	L=10.5mh, ukuchaneka 0.3%
