(m) For dual side transmitters only, in the
Test Standby Side menu, select Run
All Tests. Each test should take
about 20 s. OK should be displayed.
(n) Press RF On and set the power level
to 0 W (simultaneously press the
Power - Increase and Decrease
buttons). Set modulation to 0% (off).
(o) Set the analog meter to display
reflected power on the 0 to 120 W
scale (see 3.6.8.2).
(p) In the Meters menu, use the f or g
buttons to display the average PA volts
for side A.
(q) Slowly increase the RF output until the
PA voltage is 65 V dc while ensuring
the reflected power does not exceed
the reflected power limit of 80 W. The
output power from the A side RF
power module should be 100 r 20 W.
(r) Increase the RF output to rated power.
If a dual side system was not
purchased, proceed to step (y).
(s) Set power to 0 W. Press RF Off. Set
the active side to B.
(t) There should be no alarms indicated
on the System Diagram or the GUI.
(u) In the Meters menu, use the f or g
buttons to display the average PA volts
for side B.
(v) Increase the RF output until the PA
voltage is 65 V dc while ensuring the
reflected power does not exceed the
reflected power limit of 80 W. The
output from the B side RF power
module should be 100 r 20 W.
(w) Increase the RF output to rated power.
(x) Set the active side to A. The
transmitter should resume operating at
full power.
(y) If the dc power source option was not
purchased, proceed to step (cc).
(z) Apply dc power. In the GUI set the
Requested Power Source to BOTH
(see 3.6.9).
(aa) Switch the ac power switch on the
back of the transmitter to OFF. The
transmitter should continue to run at
full power on the dc source (battery).
(bb) Switch the ac power switch on the
back of the transmitter to ON. The
transmitter should return to operating
in ac mode.
(cc) Complete the Standard Adjustments in
Section 4 of this manual.
(dd) Set the RF output power to 0 W. Press
Control - RF Off.
