2.3 Connectors

Channel Input BNC Connector (CH1, CH2)

This is the channel’s input connector. Attach the oscilloscope probe or BNC cable to the BNC connector.

EXT TRIG

It’s a external trigger input, which can be used as a source in several of the trigger types.

Probe Compensation Terminals

Use the signal at these terminals (probe compensation terminal and ground terminal) to match each probe’s characteristics to the oscilloscope channel to which it is connected.

Section 3  Using the Vertical System

3.1 To turn waveforms on or off (channel or math)

Pressing the channel (CH1 MENU, CH2 MENU), and MATH MENU front panel keys have the following effect:

? If the waveform is off, the waveform is turned on and its menu is displayed.

? If the waveform is on and its menu is not displayed, its menu will be displayed.

? If the waveform is on and its menu is displayed, the waveform is turned off and its menu is displayed.

3.2 To adjust the vertical scale

When an input channel waveform is on:

? Turn its vertical scale knob (VOLTS/DIV) to change the amplitude per division setting.

? The amplitude/div setting changes in a 1- 2- 5 step sequence from 2 mV/div to 5 V/div (with “1X” probe attenuation).

? The amplitude/div setting is displayed in the status bar at the bottom of the screen.

NOTE Either ground or the center of the screen is used as a reference. The “center of screen”  reference is not available for math function.

3.3 To adjust the vertical position

Adjusting their vertical position lets you compare waveforms by aligning them above one another or on top of each other.

When an input channel waveform is on:

? Turn the vertical position knob (POSITION) to change the vertical position of the waveform on the screen.

? Push the vertical position knob to “zero” the ground reference (in other words, move it to the center of the screen).

NOTE

? The ground reference symbol on the left side of the display moves with the waveform.

? Notice that, as you adjust the vertical position, a message showing the position of the ground reference relative to the center of the screen is temporarily displayed at the bottom corner of the screen.
