e. Control the CX3300 and acquire the waveform as same as the step 3-c.
And read the marker Y value then record it as follows.
• Ioff_negative=Y
f. Disable the current source (Keysight B2900) output.
9. Set the 10 A range user calibration data as shown below.
a. Press the
Menu key several times to open the Configuration dialog box. The
Menu key is located above the Horizontal control on the front panel.

High Resol
ution Mode: OFF
Gain=A
Offset=Ioff_offset
High Resolution Mode: ON
Gain=B
Offset=Ion_offset
Where, A and B values can be calculated by the following formulas.
• A=20/(Ioff_positiveIoff_negative)
• B=20/(Ion_positiveIon_negative)
d. Click the Apply button to memorize the Gain and Offset values.
To enable the user calibration, set the ON/OFF switch to ON.
