模拟示波器 TEK2445A

厂家: 美国泰克

• 150MHz
• 四个独立通道
• 5mV - 5 V/DIV
• 10ns - 0.5 S/DIV
• ADD，ALT，CHOP 功能
• 游标读值显示
• 输入阻抗 1兆欧姆
• 本机型属专业级机种，频宽高达150MHz，很适合量测及维修等作业。本机型具有游标读值显示功能,利用此项功能可直接量取波形之电压、频率、周期等波形各项资料，并直接显示在荧幕上，读取方便，免去计算麻烦。

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, selectable 1 Mohm/50 ohms inputs, even an automatic front-panel DC balance adjust.
