Frequency/Amplitude
3.
REF SET
Press
[REF)
to turn on the reference mode and to set the current
RF
output setting
as
the reference value. The reference value
is stored in non-volatile memory until you replace it by pressing
(REFSET)
again.
When you press
(-SET),
the
A
symbol is displayed between the
value and the units. When
A
appears, the displayed value indicates
the offset between the reference value and the
RF
output signal.
The
RF
output signal is not changed when you press this key.
Units
When you press
(REF]
for frequency, values can be entered in
MHz
or
kHz.
For
amplitude, values can be entered in any
of
the amplitude
units provided, but they are displayed in dB only.
4.
REF ON/OFF
Press
[REF
ON/OFF] to turn off the reference mode
if
it is on,
or
to
turn
on the reference mode without changing the reference value.
When you turn on the reference mode, the displayed value indicates
the offset between the reference value and the current
RF
output
setting.
The
RF
output signal is not changed when you press this key.
Output
Power
If
the
RF
output power seems too low, look for
A
in the display
between the power level value and the dB indicator. The
A
tells you
that reference mode is turned on. The displayed value is
not
the
output power level;
it
is the offset between the reference value and
the output power.
To
exit
the reference mode, press
CREF
ON/OFF~.
You
can then reset the output power to the desired level.
