4.6.2 Delta T Gain, Trigger Delay Time & Pulse Adjust Input A
Proceed as follows to do the calibrations:
1. Press
to select calibration step Delta T (CL 0700):IDLE
2. Connect the test tool to the 5500A as shown in Figure 4-4.

3. Set the 5500A to source a 1V, 1 MHz fast rising (rise time ≤ 1 ns) square wave
(SCOPE output, MODE edge).
4. Set the 5500A to operate (OPR).
5. Press
to start the calibration.
The Delta T gain, Trigger Delay (CL0720), and Pulse Adjust Input A (CL0640) will
be calibrated.
6. Wait until the display shows Pulse Adj A (CL 0640):READY.
7. When you are finished, set the 5500A to Standby.
8. Continue at Section 4.6.3.
