d. Click the on-screen box to Verify the probe host terminations.
e. Set the Vertical Scale to 100 mV/division.
f. Use the calibrator to measure the input impedance of the oscilloscope and
enter the value in the test record.
8. Repeat the tests at 50 Ω as follows:
a. Set the calibrator impedance to 50 Ω.
b. Push the front-panel oscilloscope Vertical V menu button.
c. Set the Termination to 50 Ω.
d. Repeat steps 4 through 6.
9. Repeat the procedure for all remaining channels as follows:
a. Push the front-panel button to deselect the channel that you have already
tested.
b. Push the front-panel button to select the next channel to be tested.
c. Move the calibrator connection to the next channel to be tested.
d. Starting from step 3, repeat the procedure until all channels have been
tested.
10. Press the Menu Off button.
Check DC 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 channel 1 input.
2. Push the front-panel Default Setup button.
3. Set the oscilloscope impedance to 50 Ω as follows:
a. Push the front-panel oscilloscope Vertical V menu button.
b. Set the Termination to 50 Ω.
