Technical Specifications
VERTICAL DEFLECTION (Y)
Deflection Coefficient (CH1 & CH2) 1mV/div to 5V/div. 5mV/div to 5V/div in 10 calibrated steps in 1-2-5 sequence. x5 Magnification increases the sensitivity to 1mV/div to 1V/div.
Accuracy x1 : ±3%, x5 : ±5%.
Variable 1 / 2.5 times uncalibrated continuously variable control extends the Deflection Coefficient to more than 12.5V/div.
Bandwidth x1 : DC to 40MHz (-3dB), dc coupled.
10Hz to 40MHz (-3dB), ac coupled.
x5 : DC to 7MHz (dc coupled)
10Hz to 7MHz (ac coupled).
Rise Time 8.8 ns or less.
Display Modes CH1 only, CH2 only, CH1 & CH2 alternate or chop mode, Algebraic additon CH1+CH2, Algebraic subtraction CH1 - CH2, CH2 invert & X-Y.
Input Impedance 1M ohms & 25pF approx.
Maximum Input Voltage 300 Volts (dc + peak ac).
Internal Trigger Signal CH1 or CH2.
TIME BASE
Sweep Speed 20 Calibrated steps. 0.1µs/div to 0.2s/div in 1, 2 & 5 sequence.
Sweep Magnifier x5 Magnification.
Accuracy ±3%.
Variable Uncalibrated continuously variable control between steps, extends slowest sweep speed to 0.5s/div (approx.).
