RF
Output On/Off
The RF
OUTPUT
[ON/ OFF] key
allows the
operator
to enable or disable
the RF output
of
the Generator. This feature is useful in zeroing
a power meter, finding
the noise
floor of a
system, or determining the presence or source of an unknown
signal.
At
power-on, the RF output of the Generator
assumes the state it
was
in
when the Generator
was turned off. Pressing
the
RF OUTPUT [ON/ OFF]
key disables the
output of the
Generator and causes the RF OFF indicator (in
the STATUS display field)
to light. If the RF
ON/ OFF was off
at power-on,
pressing the [ON/ OFF] key will
enable output.
2-18. Modulation On/Off and Rate
The MODULATION ON/ OFF keys allow the operator to select
any combination
of
modulation or no
modulation. The MODULATION display field
indicates what
combination
of modulation has been selected. Each modulation key is a push-on push-off
type (except the
[400/
1000]
key).
The
[400/ 1000]
key toggles the internal modulation oscillator
between
400
and 1000
Hz. The
400 Hz and 1000 Hz indicators are lit only
when Internal AM, FM, <^M, or Pulse
modulation is
enabled.
