Power Out—
The current RF output power of the amplifier. The
RF output is continuously monitored and displayed on this
menu.
Atten Set—
The current attenuator setting. This is only available
when High Voltage is OFF.
RFLTD PWR—
The current value of reflected power present at
the output of the amplifier. Reflected power is continuously
monitored and displayed on this menu. This is only available
when High Voltage is ON.
Ew—
Current Helix Voltage.
Iw—
Current Helix Current.
Ef—
Current Heater Voltage.
Temp—
Current TWT collector temperature in either Fahrenheit
or Centigrade.
Note
The default values for the units displayed on the Status 2 Menu is set
via the Setup Menus which are discussed later in this chapter.
Three of the softkeys of the
Displayall Menu
are active. The
functions of these three softkeys are:
[Softkey 1]—
Temporarily changes the units used for both the RF
Output and RF Reflected Power displays. Cycles one step each
time [Softkey1] is pressed. The sequence of the steps is:
Watts dBm dBw Watts, etc.
[Softkey 2]—
Same as [Softkey 1].
[Softkey 4]—
Temporarily changes the temperature units used
for the temperature data display. Toggles between degrees
F (Fahrenheit) and degrees C (Centigrade.)
The [
Enter
] key is pressed to go back to the
Status 2 Menu
from
the
Displayall Menu
.
The third line of the Displayall Menu shows the Helix Voltage
(Ew) in kilovolts (DC) and the Helix Current (Iw) in milliamperes.
The fourth line of the display shows the Heater Voltage (Ef) and
the TWT collector temperature (Temp) in Fahrenheit or
Centigrade.
