400 MHz Analog Oscilloscope. Four channel. Rise Time: 0.875 ns ( >= 5 mV/div). Deflection Factor: 2 mV/div to 5 V/div, continuously variable between V/div settings (CH 1 and CH 2). 100 mV/div and 500 mV/div (CH 3 and CH 4). Deflection Factor Basic Accuracy: ±2%, measured at any V/div with a 4- or 5-div signal, centered on screen (CH 1 and CH 2). ±10% (CH 3 and CH 4) between 15°C and 35°C. Input Coupling and Max Voltage: (1 M-Ohm) AC, DC, GND; Max input voltage: 400 V (DC + peak AC). (50 ohm) Max input voltage: 5 V RMS average for 1 sec, ±50 V peak. Input R and C: 1 M-Ohm ±5% and 15 pF ±2 pF or 50 ohm (nominal). Channel Isolation: >= 100:1 at 100 MHz, >=50:1 at nominal bandwidth (CH 1, CH 2), >=50:1 at 100 MHz (CH 3, CH 4). AC-Coupled Lower -3 dB Point: 10Hz or less. 1 Hz or less with standard accessory probe. Chop Mode Switching Rate: 2.5 MHz ±0.2% (20 us/div to 2 us/div). 1 MHz ±0.2% for all other sweep speeds. Display Modes: A (main sweep), A INTENsified, ALTernate, A INTEN with B (delayed sweep) and B. In X-V mode, CH 1 provides X-axis (horizontal) deflection. A Sweep Time Base Range: 500 ms/div to 5 ns/div (to 500 ps/div with X10 magnification). B Sweep Time Base Range: 50 ms/div to 5 ns/div (to 500 ps/div with X10 magnification). A and B Trigger Coupling: DC, Noise Reject, HF Reject, LF Reject, AC. Trigger Level Range: ±18 times V/div setting for CH 1 and CH 2. ±9 times V/div setting for CH 3 and CH 4. Trigger Sensitivity to 50 MHz from CH 1 or CH 2: 0.35 div DC coupled; <=1.2 div noise reject coupled; 0.5 div from DC to 30 kHz HF reject coupled; 0.5 divs from 80 kHz LF reject coupled; 0.35 divs from 60 Hz AC coupled. Display Graticule Size: 68 mm x 85 mm. Option 10, IEEE-488 GPIB Interface
