Check Vertical Position
Range
This test check
s the offset range for eac h c hannel.
1. Connect the oscilloscope to a DC voltage source to run this test. If using the
Fluke calibrator as the DC voltage source, connect the calibrator head to the
oscilloscope channel to test.
2. Push the front-panel Default Setup button to set the instrument to the factory
default settings.
3. Push the channel button (1, 2, 3, or 4) for the channel th
atyouwanttocheck.
4. Push the bottom-bezel Probe Setup button, and then push the Set to 1 X
side-bezel button.
5. Use the Vertical Scale knob to set the oscilloscope to 200 mV/div.
6. Use the Vertical Position knob to place the trace at the bottom of the display
(-4 divisions).
7. Set the Offset to +1 V:
a. Push the bottom-bezel More button to select Offset.
b. Use Multipurpose knob a to set the offset to 1.000 V.
8. Set the DC Voltage source to +1.800 V.
9. Check that the vertical trace i s now within 0.2 divisions of the Zero volt line.
Record Pass or Fail in the test record.
10. Set the DC Voltage source to 0 V.
11. Push the Set to 0V side-bezel button.
12. Use the Vertical Position knob to place the trace at the top of the display
(+4 divisions).
13. Use Multipurpose knob a to set the offset to –1.000 V.
14. Set the DC Voltage source to –1.800 V.
15. Check that the vertical trace is now within 0.2 div
isions of the Zero volt line.
Record Pass or Fail in the test record.
16. Set the DC Voltage source to 0 V.
