The amplifier may be operated via the RS-485 serial interface, discrete interface or the front
panel controls and display. Each method provides full access to the unit’s functions including
system monitoring of all key operating parameters, control of output attenuation and amplifier’s
operational status.
In LOCAL mode, with the aid of the keypad and the LCD display, the operator can navigate
through a series of menus on the front panel which allow the setting of key parameters and digital
display of critical performance indicators. A series of LED indicators provides a summary of the
operational status of the amplifier, see
