6-12 681XXC OMUNLEVELED is DisplayedTroubleDescription: This message is displayed to indicate that the
RF output is unleveled.
Step 1 Check that the output power does not exceed the specified
leveled-power rating and that the RF OUTPUT connector is
terminated into a 50Wload.
qReduce the power level to not exceed the specified
leveled-power rating or terminate the RF OUTPUT
connector with a 50Wload.
qIf error message remains displayed, call a service
technician.
RANGE is DisplayedTroubleDescription: This message is displayed in the frequency
parameters area to indicate that (1) the analog sweep start frequency
entered is greater than the stop frequency,(2) the dF value entered
results in a sweep outside the range of the instrument, (3) the step size
value entered is greater than the sweep range, (4) the number of steps
entered results in a step size of less than 1 kHz (0.1 Hz with Option 11)
or 0.1 dB (0.01 mV), or (5) the step sweep time entered divided by the
number of steps entered results in a dwell time of <10 ms.
Step 1 Check that (1) the analog sweep start frequency entered is
not greater than the stop frequency,(2) the dF value entered
does not try to set the frequency sweep outside the range of
the signal generator,(3) the step size entered is not greater
than F2 minus F1, (4) the number of steps entered does not
result in a step size that is smaller than the resolution of the
instrument, or (5) the step sweep time and number of steps
does not result in a dwell time of <10 ms.
qEnter a valid sweep start frequency,dF value, step size,
or number of steps.
qIf the error message remains displayed, call a service
technician.
