Thresholds
Each RF power monitored by the AC should be below a given maximum
threshold. In case a value is beyond the threshold, the AC indicates an
alarm condition. The values of the thresholds are displayed in the Thresholds
menu.
Clock/Date
This menu is used to set the current date and time. Once the changes are
confirmed by pressing the RET button, the AC synchronizes all of the
AMs of the transmitter.
Backlight
The display is provided with a backlight. A Screensaver may be enabled
to make the lamp last longer. When it is, the light is automatically switched
off after 8 minutes without any button being pressed, and it is switched on
again as soon as any button is pressed.
Release
The Release menu shows the kind of the transmitter, the version of the AC
firmware and the serial number of the equipment.
Rms/Peak
The Amplifier Control can detect Peak and RMS RF powers. Tbe Peak
power is used in analog transmitter (FM or TV), the RMS power is used
in digital transmitter.
The user can choose the power detection mode by using the RMS/Peak
menu. In dual-mode (analog and digital) transmitter, the switch between
RMS and Peak power detection can be linked to an ex-ternal input signal
on TELEMEASURES port (see Rear Panel paragraph for more
information). Se-lect TLC item in the RMS/PEak menu to enable this
feature.
