5.6.5 Input D LF-HF Gain
Proceed as follows to do the Input D LF-HF Gain calibration:
1. Press
F2
to select the first calibration step in Table 5-4.
2. Connect the Test Tool to the 5500A as shown in Figure 5-6.
3. Set the 5500A SCOPE output to source the signal required for the first calibration
point in Table 5-4.
4. Set the 5500A in operate (OPR) or standby (STBY) as indicated.
5. Press
F3
to start the calibration.
6. Wait until the display shows calibration status
:READY .
7. Press
F2
to select the next calibration step, set the 5500A to the next
calibration point signal, and start the calibration.
Continue through all calibration points of Table 5-4.
