SQUELCH ON OFF
SRC PWR OFFSET
SRC PWR ON OFF
The tracking generator warmup period begins when the source power is
NOTE
set to ON and the G is displayed in the special functions area. The
tracking generator is not turned on automatically when the analyzer is
turned on, unless the power-on state is specified as having the source
power set to ON.

Adjusts the squelch level. The value is displayed in
the active function block, in dBm. The squelch level is
also indicated by a dashed line across the display. A
marker must be active and located above the squelch
line for demodulation to occur when squelch is on. Note
that in zero span, squelch for AM is inactive.
Front-panel key access:
For 8560E/EC Option 002. Allows you to offset the
displayed power of the tracking generator. Offset values
may range from −100 dB to +100 dB.
Using the source-power-offset capability of the tracking
generator allows you to take system losses into account,
thereby displaying the actual power delivered to the
device under test.
Front-panel key access:
For 8560E/EC Option 002. Activates (ON) or
deactivates (OFF) the output power of the tracking
generator. The power level can then be adjusted using
the data keys, step keys, or knob. The output power
level can be varied from −10 dBm to +2.8 dBm, with 0.1
dB resolution.
When source power is on, a G appears in the special
functions area at the left side of the display screen.
Front-panel key access:
For 8560E/EC Option 002. Allows the user to set
the step size of the source power level, source power
offset, and power-sweep range functions. The step size
may be values from 0.1 dB to 12.8 dB.
Front-panel key access:
Activates the start frequency and sets the spectrum
analyzer to the start-frequency stop-frequency mode.
START FREQ can be adjusted using the data keys, the
step keys, or the knob. When adjusting START FREQ,
if the selected start frequency exceeds the stop
frequency, the stop frequency increases to equal the
start frequency plus the minimum swept span (100 Hz
x N, where N is the local oscillator harmonic).
