• 150mhz
• 四個(gè)獨(dú)立通道
• 5mv - 5 v/div
• 10ns - 0.5 s/div
• add，alt，chop 功能
• 游標(biāo)讀值顯示
• 輸入阻抗 1兆歐姆
• 本機(jī)型屬專業(yè)級機(jī)種，頻寬高達(dá)150mhz，很適合量測及維修等作業(yè)。本機(jī)型具有游標(biāo)讀值顯示功能,利用此項(xiàng)功能可直接量取波形之電壓、頻率、周期等波形各項(xiàng)資料，并直接顯示在熒幕上，讀取方便，免去計(jì)算麻煩。

the 2445a oscilloscope provides powerful features and portable versatility. four independent channels, 150mhz bandwidth at probe tip, 250mhz minimum triggering bandwidth, 1ns/div sweep rate, and waveform cursors provide exceptional flexibility. other features include crt readout, delayed sweep, delta v, delta t, 1/delta t, tracking & independent modes, se-lectable 1 mohm/50 ohms inputs, even an automatic front-panel dc balance adjust.
