技術(shù)特性

• Vertical System
  ＊ Deflection Factor: 2 mV/div to 5V/div, （CH 1 and CH2）.  100mV/div and 500 mV/div （CH3 and CH4）
  ＊ Frequency and Step Tr Response （-3 dB Bandwidth）/（Tr=0.35/BW） - BW/Rise Time: 200 MHz/1.75 ns
  ＊ Bandwidth Limiter: Reduces upper -3dB to 20 MHz
  ＊ Input Coupling and Max Voltage: （1 Mohm） AC, DC, GND; Max input voltage: 400 V （DC + peak AC）. （50 ohm） Max input voltage: 5 V RMS
  ＊ Input R and C: 1 Mohm and 15 pF or 50 ohm （nominal）
• Horizontal System
  ＊ Display Modes: A （main sweep）, A INTENsified, ALTernate, A INTEN with B （delayed sweep） and B.  In X-Y mode, CH 1 provides X-axis （horizontal） deflection
  ＊ A Sweep Time Base Range: 500 ms/div to 10 ns/div （to 1 ns/div with X10 magnification）
  ＊ B Sweep Time Base Range: 50 ms/div to 10 ns/div （to 1 ns/div with X10 magnification）
• Automatic Measurements: Period; Volts; Rise time, Fall time; Time A-B （from % to %）; Time A-B （between two voltages）; Pulse Width
• Triggering: A and B Trigger Coupling: DC, Noise Reject, HF Reject, LF Reject, AC
• X-Y Operation
  ＊ X-Axis Deflection Factor Range, Variable Range, and Accuracy: Same as CH 1
  ＊ X-Axis Bandwidth: DC to 3 MHz
