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.
