ST-203 Simultaneous Multi Electron Beam Source Unit
This is used when 2 electron beam sources will be used simultaneously with 1 power supply. There will be 2 operation panels, each one is assigned for dedicated operation of one of the 2 electron beam sources.
It is possible to use different types of electron beam sources,but there may be limitations on the accelerating voltage range, etc. depending on the combination.
ST-EXTSIG External Signal Control
Incorporated in to the operation panel. In addition to the standard 9 types of external control signals, enables the external output of various other signals, such as the emission current confirmation signal
