5. Set the 5502A to source a sine wave according to the first test point in
Table 4-8.
Because no 50 Ω termination is applied, the 5502A leveled sine wave output
amplitude will be twice the set value.
6. Observe the readings
A, B, C, and D and check that they are not outside the
range shown under the appropriate column.
7. Continue through the test points.
8. When you are finished, set the 5502A to 0 (zero) Volt and Standby.

Time Base Test
Proceed as follows to test the time base accuracy:
1. Connect the Test Tool to the 5502A as shown in Figure 4-6.
For the Fluke 190-502 and 190-504 you must use the Fluke TRM50 50 Ω
terminator.
