Special Operating Modes
Self Calibration of Analog Output Levels (continued)
You can also start the procedure by sending the following command string to the generator’s comm port while the unit is running:
AVCM 1; fmtu <carriage return>
Details on the connections can be found on a later page.
2)The LCD will display a prompt asking you to make the connections for calibration.
5)Connect the 50 Ohm feedthrough terminators and two 50 Ohm coaxial cables as shown. The calibration routine can compensate for small losses in the cables normally with the generator if they are used for the self calibration connections.
4)Rotate the Image knob to start the self calibration operation.
5)Self calibration takes about one minute per module. The LCD will show a progress report during this time. Any messages indicating that the unit could not bring an adjustment within calibration may indicate a problem with your connections or with the module itself.
