Chapter 1 Performance Tests

Test 3: Channels 1 and 2 Frequency Sensitivity (HP 53131A/132A Only)

100 kHz to 100 MHz Sensitivity for HP 53131A/132A

1Connect the timebase output of the unit with the better timebase to the timebase reference input of the other unit as shown in Figure 1-7.

For this test, make sure you always use the unit (HP 53131A/132A or HP 8663A) that contains the better 10 MHz timebase as the output source as shown in Figure 1-7.
