8. Repeat the test
sat50Ω as follows:
a. Set the calibrator impedance to 50 Ω.
b. Push the front-panel oscilloscope Vertical Menu button.
c. Set the Te rmination to 50 Ω.
d. Repeat steps 4 through 6.
9. Repeat the procedure for all remaining channels as follows:
a. Push the fr
ont-panel button to deselect the channel that you have already
tested.
b. Push the f
ront-panel button to select the next channel to be tested.
c. Move the calibrator connection to the next channel to be tested.

tested.
10. Press the Menu Off button.
Check D
C Balance
This test checks the DC balance. You do not need to connect any test equipment
(other than the 50 Ω terminator) to the oscilloscope to perform this check.
1. Attach a 50 Ω terminator to the oscilloscope c hannel 1 input.
2. Push the front-panel Default S etup button.
3. Set the oscilloscope impedance to 50 Ω as follows:
a. Push the front-panel oscilloscope Vertical Menu button.
b. Set the Termination to 50 Ω.
4. Set the Bandwidth to 20 MHz
5. Set the Horizontal Scale to 1 ms/division.
