●VERTICAL  DEFLECTION  (2 Identical Channels)

Bandwidth and Rise time

DC to at least 100MHz and rise time 3.5ns or less. DC to at least 5MHz and rise time 7Ons c less at magnifier extends.

Lower -3dB point, AC coupling 10Hz or less.

Deflection Factor

5mV/div to 5V/div in 10 calibrated steps, 1-2-5 sequence. Uncalibrated continuous control extends deflection factor to at least 12.5 Volt per division in the 5 Volts/div position. x10 magnifier increases sensitivity of each deflec­tion factor setting to 500V/div.
