No Result; Meas invalid with
I/Q inputs
E The current measurement does not
support I/Q input; switch to the RF or
another input or select a different
measurement

Uncalibrated Summary
status bit
only
This bit is the summary bit for the
STATus:QUEStionable:INTegrity:UNCali
brated sub-register.

Input Overload
W
141 4
Input Overload;ADC over
range
W The signal at the input to the IF section
is too high. You should increase the
attenuation or lower the signal level.
141 4
Input Overload;I/Q ADC over
range
W The I or Q input exceeds the ADC upper
limit.
141 4
Input Overload;I/Q Voltage
over range
W The input voltage on the I or Q channel
exceeds the channel limit. In differential
mode the over voltage may occur
without causing an ADC overload, for
example, if I is at +5.01 V and I-bar is at
+5.0 the ADC will be in range but both I
and I-bar will exceed the voltage limit.

Insufficient Data; Incr.
Demod Time
E There is insufficient acquisition data to
provide accurate metrics. You should
increase the Demod Time to acquire
enough data.
147 7
Insufficient Data; frequency
list empty
E A measurement was attempted with List
frequency mode or a SCPI query of the
frequency list table was made and the
frequency list table is empty.
147 7
Insufficient Data; ENR table
empty
E A measurement was attempted or a
SCPI query of an ENR table was made
and there were no entries in the relevant
ENR table (Common, Meas or Cal).
147 7
Insufficient Data; Loss
table empty
E A measurement is attempted or a SCPI
query of a before or after loss table is
made and there are no entries in the
relevant loss table
