(requires ENG access)
bbs balance (master|slave) (high|low) <piston>

Variables piston Specifies the beam piston as 0% to 50% for the master and -50% to 50% for the slave.

Description Perform a beam-balance ( master / slave ) specially designed for calibrating bipolar imaging. Attempting to calibrate bipolar imaging using the standard beam-balance is difficult due to the number of variables involved in the calibration. The solution is to fix one polarity and adjust the other polarity.

The monitor command bbs balance master (high|low) <piston> will configure the master profile. The master profile will be reduced by the specified beam piston to provide sufficient beam piston for configuration of the slave profile.

The monitor command bbs balance slave (high|low) <piston> will configure the slave profile. The slave profile will be reduced, without modifying the master profile, to configure the specified beam piston.

Note that typically the maximum beam piston will be 30%. Thus the master profile should be reduced by 15% and then the slave profile should be varied from 12% to -12%.
