Yang'anani kuti muwonetsetse kuti zodumphira zonse zakhazikitsidwa monga tafotokozera mu gawo la DC2222A Jumpers. Makamaka, onetsetsani kuti VCCIO (JP3) yakhazikitsidwa ku malo a 2.5V. Kuwongolera DC2222A ndi DC890 pomwe JP3 ya DC2222A ili pamalo a 3.3V kupangitsa kuwonongeka kwa magwiridwe antchito mu SNR ndi THD. Malumikizidwe osasinthika a jumper amakonza ADC kuti igwiritse ntchito zowunikira komanso zowongolera. Kuyika kwa analogi ndi DC kuphatikizidwa ndi kusakhazikika. Lumikizani DC2222A ku DC890 USB High Speed ​​Data Collection Board pogwiritsa ntchito cholumikizira P1. (Osalumikiza chowongolera cha PScope ndi chowongolera cha QuikEval nthawi imodzi.) Kenako, lumikizani DC890 ku PC yolandira ndi chingwe cha USB A/B chokhazikika. Ikani ± 9V kumalo owonetsera. Kenako ikani gwero lotsika la jitter differential sine ku J2 ndi J4.
Lumikizani jitter yotsika 2.5VP-P sine wave kapena masikweya mafunde kuti cholumikizira J1, pogwiritsa ntchito Table 1 ngati kalozera wamafupipafupi a wotchi yoyenera. Zindikirani kuti J1 ili ndi 49.9Ω termination resistor mpaka pansi.

Onani Chithunzi 1 kuti mumve zambiri za kulumikizana.
Gwero la Clock
Mukamagwiritsa ntchito chowongolera cha DC890 ndikofunikira kupereka jitter yotsika 2.5VP-P (Ngati VCCIO ili pamalo a 3.3V, koloko amplitude ayenera kukhala 3.3VP-P.) sine kapena square wave ku J1. Kulowetsa kwa wotchi ndi AC yophatikizidwa kotero kuti mulingo wa DC wa siginecha ya wotchi siwofunika. Jenereta wa wotchi ngati Rohde & Schwarz SMB100A ndiyofunikira. Ngakhale jenereta yabwino ya wotchi imatha kutulutsa jitter yowoneka bwino pama frequency otsika. Choncho akulimbikitsidwa otsika sample mitengo yogawanitsa mawotchi apamwamba kwambiri kufupipafupi komwe mukufuna. Chiyerekezo cha kuchuluka kwa mawotchi mpaka kutembenuka chikuwonetsedwa mu Gulu 1. Ngati kulowetsa kwa wotchi kumayenera kuyendetsedwa ndi logic, tikulimbikitsidwa kuti 49.9Ω terminator (R5) ichotsedwe. Kukwera pang'onopang'ono m'mphepete kumatha kusokoneza SNR ya chosinthira pamaso papamwamba ampma litude apamwamba ma frequency athandizira ma sign.
Kutulutsa Kwa data
Kutulutsa kwa data yofananira kuchokera pa bolodi ili (0V mpaka 2.5V mwachisawawa), ngati sikulumikizidwa ndi DC890, kumatha kupezedwa ndi logic analyzer, kenako kutumizidwa ku spreadsheet, kapena phukusi la masamu kutengera mtundu wa makina opangira ma digito omwe mukufuna. . Kapenanso, deta ikhoza kudyetsedwa mwachindunji mu dera la ntchito. Gwiritsani ntchito pin 50 ya P1 kuti mutseke deta. Zambiri zitha kulumikizidwa pogwiritsa ntchito m'mphepete mwa chizindikiro ichi.
