3.6.1 Standby Mode

FIGURE 8.0

–

STANDBY MODE

(Typical)

At this mode the TWT is fully warmed up, all High Voltages are OFF and only are being applied

when the amplifier goes to RF-ON mode [also known as Cathode turned on].

Some TWTs have a single Collector element, therefore only COLL1V will be display.
