Error Messages
Error number: 20
M
20 Marker search failed
This error occurs when marker search fails.
-109 Missing parameter
The number of parameters is less than that required for the command, or the parameter has
not been entered.
N
351 No downconverter unit connected
This error occurs when the downconverter is not turned on or when the USB (USBTMC)
cable is not connected even though the downconverter is enabled. Disable the
downconverter, turn on the downconverter, or connect the USB (USBTMC) cable.
111 No signal found
This error message appears when a carrier is outside the selected frequency band or the
attenuator is improperly set during execution of the
to 0 in case you measure a DUT whose output is less than - 15 dBm.
O
100 Option not installed
The command received has been ignored because of the mismatch between the contents of
an option for this instrument and the command.
This error is not generated by front key operations.
P
-220 Parameter error
When a parameter-related error other than Errors -221 through -229 occurs, that error is
displayed.
-108 Parameter not allowed
The number of parameters exceeds that required for the command.
See the command reference to confirm the required number of parameters.
210 Phase lock loop unlocked
This error occurs when the PLL circuit of the instrument becomes unlocked while the
measurement is in progress. This message may appear if the DUT's carrier signal is
unstable. If this message is displayed in the phase noise measurement, the following
problems and corrective actions are shown below.

The DUT's noise level is too large, or a large level spurious component exists in the
measurement range.
Verify the spectrum of the DUT's output signal.
Decrease the IF Gain value, or increase the sweep start value when possible.
The DUT's output signal is being modulated in frequency.
Carrier to function. Set the attenuator
