Check system noise
This test checks the system noise.
This test is valid when used on an MSO6 Series instrument. Use the following steps to check the system noise:
1. Plug a P77STCABL or P77STFLXA into the probe tip and connect the probe to a channel on the oscilloscope. The LED
on the tip should light up after loading.
2. Set the probe to Differential (A-B) mode.
3. Adjust the vertical resolution so the noise is on the screen and isn't clipping, but still takes up as much of the screen as
possible.
4. Adjust the horizontal scale to 4 μs/division.
5. Add an AC RMS measurement for the channel the probe is plugged into:
a. Tap the Add New... Measure button.
b. Tap the Amplitude Measurements panel.
c. Double-tap the AC RMS measurement to add the measurement badge to the Results bar.
d. Tap outside the menu to close it.
6. Record this measurement in the test record, it should be lower than the system noise specification.
