Ramp-Up Speed Setting
From the front panel UI, you can set the transmitter’s ramp-up speed. This setting establishes the
time it takes the transmitter to ramp up from 0 W to full power. At 100%, ramp-up speed is
approximately seven seconds. For a setting of 50%, ramp-up would be approximately 14 seconds. For
a setting of 25%, ramp-up would be approximately 28 seconds. In multi-transmitter systems that are
on a common generator or power grid, adjusting the ramp-up speed can be used to reduce the
transient load on the source during an ac power recovery (i.e., after a power failure or changeover to a
generator).
