Checks and Adjustments
3. Set both VOLTS/DiV controls to .1 V (X10 probe), set both
input coupling controls to DC, and select CH1 VERTICAL
MODE.
4. Place the tip of the Channel 1 probe on the PROBE ADJUST
terminal.
5. Using the approximately 1 kHz Probe Adjust signal, obtain a
5"-division display.
6. Set the SEC/DIV control to display several cycles of the sig¬
nal. Use the Channel 1 POSITION control to vertically center
the display.
7. Check the v^aveform presentation for overshoot and rolloff
(see Figure 4-1). If necessary, perform step 8 to adjust the
probe tow-frequency compensation. Otherwise, proceed to
step 9.
8. Rotate the sleeve on the probe head to expose the LF COMP
adjustment capacitor (see Figure 4-2). Use a low-reac¬
tance alignment tool to adjust LF COMP and obtain a square,
or nearly square, front corner on the waveform tops (Figure
4-1, top trace).
