Functions of Controls
RF
RANGE-Selects
one of
eight rf ranges from 20 to
260 Mc. This control simul-
taneously switches the inter-
nal
oscillator
circuits
and
rotates the dial drum so the corresponding
frequency
scale is in view.
RF
TUNING -
Is a fine-
tuning control used in con-
junction with the RF
RANGE
control to select the desired
output frequency.
OUTPUT
- The modulated
or un modulated
rf output
from the generator
is avail-
able at this connector.
The
output connector
accommo-
dates the rf-output cable supplied with the instrument.
RF
ON· OFF-When
set to
"OFF"
position, removes
B+
voltage
from
the variable-
frequency oscillator and reno
ders the oscillator
inopera-
tive. This control must be set to
"OFF"
to obtain the
separate 1.,4.5-, and 10·Mc output.
