直流電源的技術(shù)指標(biāo)分為兩種：一種是特性指標(biāo)，包括允許輸入電壓、輸出電壓、輸出電流及輸出電壓調(diào)節(jié)范圍等；另一種是質(zhì)量指標(biāo)，用來衡量輸出直流電壓的穩(wěn)定程度，包括穩(wěn)壓系數(shù)（或電壓調(diào)整率）、輸出電阻（或電流調(diào)整率）、紋波電壓（周圍與隨機漂移）及溫度系數(shù)。
（1） 紋波電壓：疊加在輸出電壓上的交流電壓分量。用示波器觀測其峰峰值視鏡 衛(wèi)生泵一般為毫伏量級。也可用交流毫伏表測量其有效值，但因紋波不是正弦波，所以有一定的誤差，一般直流電源的紋波電壓VP-P≤10mV。
（2） 電壓調(diào)整率：輸入電壓相對變化為±10%時的輸出電壓相對變化量，穩(wěn)壓系數(shù)和電壓調(diào)整率均說明輸入電壓變化對輸出電壓的影響，因此只需測試其中之一即可。
輸出電阻與放大器的輸出電阻相同，其值為當(dāng)輸入電壓不變時，輸出電壓變化量與輸出電流變化量之比的值.電流調(diào)整率：輸出電流從0變到大值時所產(chǎn)生的輸出電壓相對變化值。輸出電阻和電流調(diào)整率均說明負載電流變化對輸出電壓的影響，因此也只需測試其中之一即可。
