71.8.2.1.4 Kupereka Voltagndi Ripple

1. Konzani oscilloscope motere:
   ● Sikelo yopingasa: 1 ms/div
   ● Mulingo woyima: 10 mV/div
   ● Kulumikizana kwa ma Channel: AC
2. Ndi katundu wamagetsi wokhazikitsidwa ku CC mode, lembani nsonga-nsonga ya VBUS voltage pamtunda wogwiritsa ntchito zolozera pa katundu aliyense kuyambira 0 A mpaka 1 A mu masitepe 200 mA. Jambulani maulendo osachepera 10 ndikuyesa kuchuluka kwapamwamba kwambiritage, kusintha sikelo yopingasa ngati kuli kofunikira potengera kuchuluka kwa ripple.
3. Onetsetsani kuti zolembedwa zonse zili pansi pa 20 mV.

71.8.2.2 Zida Zakunja za USB
Gawoli lili ndi njira zoyesera zamagetsi pazowonjezera pogwiritsa ntchito magwero amagetsi akunja a USB.
71.8.2.2.1 Zida
Zida zotsatirazi ndizofunika:

• DMM yokhala ndi mawaya 4 Kelvin mphamvu yomveka
• USB Breakout Board (tsamba 835) (ngati chowonjezera chimagwiritsa ntchito pulagi ya USB-A)
• USB-IF certified USB-C receptacle board board (ngati chowonjezera chimagwiritsa ntchito pulagi ya USB-C), onani https://www.usb.org/compliancetools#anchor_electricaltools
• Gwero lamagetsi la USB-C PD (ngati chowonjezera chimagwiritsa ntchito pulagi ya USB-C)

71.8.2.2.2 Kukhazikitsa Mayeso

1. Chotsani C962 kuchokera pazowonjezera.

71.8.2.2.3 Round-Trip DC Resistance (DCR)

1. Lumikizani "Force" ndi "Sense" kutsogolera kwa DMM ku VBUS ndi GND zizindikiro mu chowonjezera.
2. Kufupikitsa zizindikiro za VBUS ndi GND pa pulagi ya USB pogwiritsa ntchito bolodi la USB.
3. Konzani DMM kuti ipange muyeso wa mawaya anayi a Kelvin.
