Overload : Reduce Signal and press <ESC> (Input
Overload Tripped )
This message applies to the Agilent Technologie s
E4401B and E4411B only . A signal has been applied t o
the input connector that caused the overload protectio n
circuitry to engage . The input signal must be reduced.
After the signal is reduced, press ESC to reset the
overload detector so that you can continue using the
analyzer.
CAUTION Exposing the analyzer to high levels of input power over a prolonge d
period of time can damage the internal circuitry .
(RF Align Failure) status bit only, no messag e
A failure has occurred during the alignment of the R F
section. Measurement results may be invalid .
Signal Ident On, Amptd Uncal (Signal Ident On )
Indicates that the amplitude measurement could be
uncalibrated because the signal identification feature i s
on.
Source LO Unlevel (Source LO Unleveled )
The internal circuitry of the local oscillator (LO) in th e
tracking generator has become unleveled. This
condition must be corrected to make valid
measurements .
Source LO Unlock (Source Synth Unlocked )
The phase-locked circuitry of the local oscillator (LO) i n
the tracking generator has become unlocked . This
condition must be corrected to make valid
measurements .
