Frequency Measurement
Proceed as follows to verify the Frequency Measurement function:
1.
Connect the UUT as shown in Figure 5.
2.
Set the UUT to the Frequency Measurement function.
3.
Select the <20 Hz range for the first step. Use the
≥
20 Hz range thereafter.
4.
Set the 5500A to the first test point in Table 7.
5.
Observe that the frequency reading on the UUT is within the range shown.
6.
Continue through the test points, using the
≥
20 Hz range of the UUT.
7.
When you are finished, set the 5500A to [STANDBY].
