-214 Trigger deadlock
TRIG:SOUR was set to HOLD or BUS and a READ? or MEASure? was
attempted, expecting TRIG:SOUR to be set to IMMediate.
-220 Parameter error;Frequency list must be in ascending order.
Indicates that the frequencies entered using the
MEMory:TABLe:FREQuency command are not in ascending order.
-221 Settings conflict
This command occurs under a variety of conflicting conditions. The
following list gives a few examples of where this error may occur:
•If the READ? parameters do not match the current settings.
•If you are in fast mode and attempting to switch on for example,
averaging, duty cycle or limits.
•Trying to clear a sensor calibration table when none is selected.
-222 Data out of range
A numeric parameter value is outside the valid range for the command.
For example, SENS:FREQ 2KHZ.
-224 Illegal parameter value
A discrete parameter was received which was not a valid choice for the
command. You may have used an invalid parameter choice.
For example, TRIG:SOUR EXT.
-226 Lists not same length
This occurs when SENSe:CORRection:CSET:STATe is set to ON and
the frequency and calibration lists do not correspond in length.
-230 Data corrupt or stale
This occurs when a FETC? is attempted and either a reset has been
received or the power meter state has changed such that the current
measurement is invalidated (for example, a change of frequency setting
or triggering conditions).
-231 Data questionable;CAL ERROR
Power meter calibration failed. The most likely cause is attempting to
calibrate without applying a 1 mW power to the power sensor.
-231 Data questionable;Input Overload
The power input to Channel A exceeds the power sensor’s maximum
range.
