4.5.2 Input 1 Frequency Response Upper Transition Point Test
Proceed as follows to test the Input 1 frequency response upper transition point:
1. Connect the test tool to the 5500A as for the previous test (see Figure 4-2).
2. Select the AUTO test tool setup:
• Press
to select the MENU.
• Press
till SCOPE is highlighted.
• Press
to select SCOPE mode
3. Select the following test tool setup:
• Press
to select menu SCOPE SETUP.
• Press
to highlight Input 1 Reading
• Press
to go to Input 1 READING.
• Press
to highlight AC + DCrms.
• Press
to confirm;  mark changes to ■
• Press
to highlight Input 1 Coupling.
• Press
to select the Input 1 Coupling menu.
• Press
to highlight DC Coupling.
• Press
to confirm;  mark changes to ■.
• Press
to return to SCOPE.
4. Set the 5500A to source a leveled sine wave of 1.2V peak-to-peak, 50 kHz (SCOPE
output, MODE levsine).
5. Adjust the amplitude of the sine wave to a reading of 424 mV ± 8 mV.
6. Set the 5500A to 20 MHz, without changing the amplitude.
7. Observe the Input 1 trace and check the reading is ≥ 297 mV.
8. When you are finished, set the 5500A to Standby.
Note
The lower transition point is tested in Section 4.5.9.

2. Select the AUTO test tool setup:
• Press
to select the MENU.
• Press
till SCOPE is highlighted
• Press
to select SCOPE mode.
