Adjustments
Input LF-HF Gain
1.
Press F2 to select the
fi
rst calibration step in the table. (See Table 12.)
2.
Connect the instrument to the 5500A as shown. (See Figure 12.)
Figure 12: Input LF-HF gain test setup
3.
Set the 5500A to supply a 1 kHz square wave (SCOPE, MODE volt, SCOPE Z 1 M
Ω
), to the
fi
rst calibration point
in the table.
WARNING.
Dangerous voltages will be present on the calibration source and connection cables during the following steps.
Verify that the calibrator is in standby mode before making any connection between the calibrator and the instrument.
4.
Set the 5500A to operate (OPR).
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, and start the calibration. Continue
through all calibration points in the table.
