153 RF EEPROM operate
fail
Indicates an error when writing an
alignment file.
152 Alignment file
oversize
Indicates the alignment file has an
error or invalid data.
151 DSP boot fail
Indicates the analyzer cannot
process the measurement currently.
Wait for the analyzer to reboot. If
the analyzer is frozen, try to restart
the analyzer.
150 Mixer overload
Indicates the first mixer is in
danger. Either increase the input
attenuation or decrease the input
signal level.
149 Mixer saturate
Indicates you need to either
increase the input attenuation or
decrease the input signal level.
147 Incorrect alignment
data in EEPROM
Indicates invalid alignment data
occurred.
143 Final IF overload
Indicates you need to either
increase the input attenuation or
decrease the input signal level.
138 USB device NOT
ready
Indicates the USB device is not
detected.
136 RBW limit to
30 kHz when in fast
sweep
Indicates the analyzer automatically
coupled the RBW to 30 kHz when in
fast sweep mode.
130 Meas uncal
Indicates the measurement is
uncalibrated due to fast sweeping
through a narrow RBW filter. Check
the sweep time, span, and band-
width settings, or use auto cou-
pling.
119 RF Board Changed
Indicates the RF board was
changed, the analyzer needs to
re-load the alignment data.
116 Cannot communicate
with RF
Indicates the MCU cannot find the
RF board.
