The difference in average voltage readings should be within the test limits of
Table 5.
If a result is not within the test limits, go to the “Troubleshooting” chapter. Then
return here.
11 Disconnect the oscilloscope calibrator from the oscilloscope.
12 Repeat this procedure to check the DC vertical gain accuracy with the
remaining Volts/div setting values in Table 5.
13 Finally, repeat this procedure for the remaining channels to be tested.
Use a Blocking Capacitor to Reduce Noise
On the more sensitive ranges, such as 0.5 mV/div, 1 mV/div, 2 mV/div, and
5 mV/div, noise may be a factor. To eliminate the noise, add a BNC Tee, blocking
capacitor, and shorting cap at the oscilloscope channel input to shunt the noise to
ground. See Figure 2. If a BNC capacitor is not available, use an SMA blocking
capacitor, adapter, and cap. See “Blocking capacitor and shorting cap in the
equipment list on page 19 for details.
