LEEM-16 Dielectric Constant Apparatus

Qaqiso ea Sehlahisoa

Dikahare tsa mantlha tsa teko

1. tekanyo ea tumello ea vacuum e0 le tumello e amanang le eona;

2. mokhoa oa ho ithuta oa ho toloka ha LC ho lekanya bokhoni bo bonyenyane;

3. ho ithuta ho sebelisa oscilloscope ea dijithale.

Litekanyetso tse ka sehloohong tsa botekgeniki

Demongolo	Litlhaloso
Jenereithara ea matšoao a DDS	Pontšo ea LCD ea lisenthimithara tse 4.3, maqhubu a leqhubu la sine le maqhubu a sekwere a 1μhz ~ 10mhz, boholo ba lets'oao 0 ~ 10vp-p, ho ka beoa le ho seta ha lets'oao la sebopeho sa maqhubu, ho sebelisoa linotlolo tsa dijithale le switch ea khouto bakeng sa tokiso.
Sehanyetsi se tloaelehileng	R1 = 1kω, ho nepahala 0.5%. r2 = 30kω, ho nepahala 0.1%
Inductor e tloaelehileng	L = 10.5mh, ho nepahala 0.3%
