IF/ADC Over Range The signal input level is to o
high, causing the analyzer analog-to-digital converte r
(ADC) range to be exceeded. This may occur wit h
resolution bandwidths less than or equal to 300 Hz in
zero span. (Agilent ESA models E4401B, E4402B ,
E4404B, E4405B, and E4407B only) .
5a 32
Over Range A 1 in this bit position indicates that the
signal is too large at the analog-to-digital converter
(ADC) .
6a 64
Under Range A 1 in this bit position indicates that
the signal is too small at the analog-to-digita l
converter (ADC).
7a 128
Insufficient Data A 1 in this bit position
indicates that there is not enough information t o
perform the measurement or function .
8a 256
Acquisition Failure A 1 in this bit positio n
indicates that the demod algorithm cannot correlat e
to the signal.

Invalid Data A 1 in this bit position indicates that
the present trace data does not reflect the existing
analyzer state. Trigger a new sweep and/or
