Vertical
This chapter describes the portion of the oscilloscope that controls
the vertical display of waveforms and the acquisition parameters. On
the portion of the front panel marked VERTICAL are the volts/division
knob, position knob, and the numbered front-panel keys for the
channel menu for each channel.
The volts/div knob changes the vertical scaling for the selected
channel. The channel indicator tells you which channel’s parameters
you are changing with the vertical menu or the knobs. The position
knob moves displayed waveforms vertically on the display. The
numbered channel keys bring up the vertical menu on the display and
turns the channel on or off. The On indicator is lit when a channel is
turned on, and the 50 Q indicator is lit when the channel input
impedance is set to 50 Q.
The 2-channel models have two input channels and an external trigger
input. The 4-channel models have four input channels and no
external trigger input. Each channel is shunted by about 7 pF at the
input BNC with a maximum input voltage of 250 V.
