FAQ
Q1: Ɔkwan bɛn so na ɔhyew nya oscillator frequency stability so nkɛntɛnso?
A: Ɔhyew mu nsakrae ma frequency drift; TCXOs/OCXOs nam compensation circuits anaa ovens so tua eyi ka.
Q2: So metumi anya nhwɛsode bi a nsakrae pɔtee bi wom (sɛ nhwɛso no, amanne kwan so agyiraehyɛde)?
A: Yiw, amanne agyiraehyɛde (logo, ɔfã nɔma, ne nea ɛkeka ho) wɔ hɔ ma nhwɛsode ahyɛde ( Kɛse sen anaasɛ ɛyɛ pɛ 10pcs). Wobetumi agye sika foforo wɔ agyiraehyɛde ahorow a ɛyɛ den ho; di kan si nsɛm a ɛkɔ akyiri no so dua ne yɛn adetɔn kuw no.
