Status
Frequency Reference Error (Freq Ref Unlocked)
The frequency reference lock loop has unlocked or is near an unlock
condition. This message can occur when either the internal or external
reference is selected. If external reference is selected, assure the frequency
of the external reference source exactly matches the entered value
displayed on the reference menu key.
The frequency reference has been tuned too far off of 10 MHz. This
condition may be corrected by cycling power on the analyzer.
Status
IF Align Failure
status bit only, no message
A failure has occurred during the IF alignment. Measurement results may
be invalid.
Status
IF Gain fixed
The autoranging function of the analyzer has been turned off (
Amplitude
,
More
,
More
,
IF Gain (Fixed)
). This setting is useful when measuring signals
that require fast measurement time, narrow resolution bandwidths (< 1
kHz), and < 70 dB of display range. For more information on this setting,
refer to IF Gain key description in the
ESA Spectrum Analyzer User’s
Guide
.
Status
IF Overload (IF/ADC Over Range)
The IF section has been overloaded. Measurement results may be invalid.
Status
Incompatible Hardware found for E4447A: Third Converter
This message is displayed when the instrument (E4447A) is turned on
(powered-up) if the Third Converter is not the correct part. The
upper-most frequency will be limited to 26.5 GHz, but the instrument will
otherwise continue to function normally. Press
ESC
to clear the message.
Status
Input is internal (no corresponding status bit)
This message applies to the Agilent Technologies E4401B and E4411B only.
Indicates the
50 MHz Amptd Ref
selection is
On
. With the 50 MHz amplitude
reference on, the input is routed through an internal signal path.
Status
LO – Stop freq must be >= min system input freq
The current measurement mode requires that the stop RF (input to DUT)
frequency must be more than the minimum system input frequency away
from the fixed LO frequency.
Status
LO Align Failure (status bit only, no message)
A failure has occurred during the alignment of the local oscillator (LO).
Measurement results may be invalid.
