技术特性

• 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
