Kidhibiti Kinachodhibitiwa na Dijiti ni kijenzi cha microwave ambacho kinaweza kudhibiti kiwango cha upunguzaji kupitia mawimbi ya dijitali.

Kanuni ya utekelezaji wake ni kudhibiti kupungua kwa ishara kwa kurekebisha hali ya sehemu ya ndani au ukubwa wa ishara ya pembejeo, kubadilisha thamani ya upinzani.Ikilinganishwa na vidhibiti vya kitamaduni vya mitambo na vipinga tofauti.

Vidhibiti vinavyodhibitiwa na dijiti vina faida zifuatazo:

1. Usahihi wa hali ya juu: Kidhibiti cha udhibiti wa kidijitali kinaweza kufikia udhibiti wa usahihi wa hali ya juu wa upunguzaji kupitia udhibiti wa dijiti, kwa kawaida kufikia usahihi wa 0.1dB au chini yake.
2. Broadband: Vidhibiti vinavyodhibitiwa na dijiti kwa kawaida hufanya kazi katika masafa ya GHz au hata THz na huwa na kipimo data kikubwa.
3. Masafa makubwa yanayobadilika: Kidhibiti kidhibiti cha dijiti kinaweza kufikia masafa inayoweza kurekebishwa kutoka 0dB hadi 60dB au zaidi, na safu ya marekebisho ni pana.
4. Udhibiti unaoweza kupangwa: Kidhibiti kidhibiti cha dijiti kinaweza kuratibiwa kupitia miingiliano ya dijitali kama vile SPI na I2C, yenye kunyumbulika kwa hali ya juu.

Vidhibiti vinavyodhibitiwa na dijiti hutumiwa hasa katika nyanja kama vile majaribio ya microwave, rada, mawasiliano na mawasiliano ya setilaiti.Kwa kuchukua maombi ya jaribio kama mfano, kidhibiti kidhibiti kidijitali kinaweza kutumika kurekebisha nguvu ya mawimbi ya majaribio ili kupima unyeti na usawa wa DUT (Kifaa Kinachofanyiwa Majaribio);Inaweza kutumika kurekebisha mfumo wa upimaji ili kuhakikisha usahihi na uthabiti wake;Inaweza kutumika kwa matukio ya majaribio ya uigaji ili kutathmini utendaji wa mfumo wa kuzuia mwingiliano dhidi ya uingiliaji kati na hali tofauti za kituo.

Qualwavehutoa bendi pana na vidhibiti vya hali ya juu vinavyodhibitiwa na dijiti kwa masafa ya hadi 40GHz.Hatua inaweza kuwa 0.25dB na masafa ya kupunguza inaweza kuwa 100dB au hata zaidi.Vidhibiti vyetu vinavyodhibitiwa na dijiti vina ubora mzuri na kuegemea juu, Na nambari za sehemu zaidi ya 70, ambazo zinaweza kukidhi mahitaji ya wateja tofauti na hutumiwa sana katika nyanja nyingi.
