■

Push the front panel Autoset button. This sets the horizontal and vertical

scale and vertical offset for a usable display and sets the trigger source to

the channel you are testing.

■

Pull down the Vertical menu, select Vertical Setup. Confirm that the

Ch1 Offset is about 0.0 mV (120 mV on >20 GHz models).

6. Verify that the channel is operational: Confirm that the following statements

are true.

■

Verify that the vertical scale readout and the waveform amplitude for the

channel under test. (See Table 4: Vertical settings on page 105.)

Table 4: Vertical settings

Setting <4 GHz models ≥4 GHz models

Without probe Without probe

Scale 500 mV 100 mV

Waveform amplitude 2 divisions 4 divisions

■

The front-panel vertical Position knob (for the channel you are

testing) moves the signal up and down the screen when rotated.

■

Turning the vertical Scale knob counterclockwise (for the channel

you are testing) decreases the amplitude of the waveform on-screen,

turning the knob clockwise increases the amplitude, and returning the

knob to the original scale setting returns the original amplitude for

that scale setting. (See Table 4: Vertical settings on page 105.)

7. Verify that the channel acquires in all acquisition modes: Pull down the

Horiz/Acq menu to select Horizontal/Acquisition Setup. . . . Click the

Performance verification (MSO/DPO70000C, MSO/DPO70000DX, and DPO7000C series)
