157 12 Invalid Data Status bit
only
This is the “invalid data indicator”, same as the
“*” in the upper right corner of the screen. It
means that the on-screen annotation does not
match the on-screen data, usually because a
measurement is pending after a settings
change. There is no message in the status line
and nothing in the history queue, but there IS
an on-screen indication and a status bit.

159 13 Settings Alert;LO may
overload IF
W If the sweep type is Swept, the start frequency
of the instrument is less than 10 MHz, and you
put Swept IF Gain in Manual High, then a
warning condition is generated and remains in
effect as long as this condition exists.
In some older analyzers this was error 1109.

mismatch; <I|Q|I,Q>
W The attenuation values of the two probes on
the I and/or Q channels differ by too much for a
valid differential reading.
159 13 Settings Alert; Acquisition
truncated
W In the Analog Demod mode, certain extreme
settings combinations will result in a required
acquisition length in excess of the capacity of
the analyzer.Increase the AF Spectrum RBW
or the RF Spectrum RBW, decrease the
Channel BW, and/or decrease the Demod
Waveform Sweep Time.
