5. TDS 500C and 700C models only: Press SHIFT ACQUIRE MENU ➞
Mode (main) ➞ Hi Res (side).
6. TDS 600B models only: Press SHIFT ACQUIRE MENU ➞
Mode (main) ➞ Average (side). Use the keypad to set Averages to 5.
7. Adjust the probe until you see a square wave with a perfectly flat top on the
display. Figure 3–2 shows where the adjustment is located.

To ensure proper coupling of your input signals to the oscilloscope, consider the
following points when you use 50 W coupling with any channel:
H The oscilloscope does not accurately display frequencies under 200 kHz if
AC coupling is selected.
H The oscilloscope reduces the maximum volts/division setting for the channel
to 1 V from 10 V (to 10 V from 100 V with a X10 probe attached), since
input amplitudes appropriate for the higher settings would overload the
50 W input.
