Troubleshooting
Error Messages
This instrument receives and detects a trigger command ("TRIG") or an external trigger
signal. But it is ignored due to the timing condition (This instrument is not in the wait-for-
trigger state, for example). Change the setup so that a trigger command or an external
trigger signal can be sent after the instrument has entered the wait-for- trigger state.
U
300 Unable to estimate adapter length
Adapter length can not be estimated at zero span. Change the frequency span other than 0.
-113 Undefined header
A command not defined in this instrument, though not illegal in the syntactic structure, has
been received. For example, when a message ":DISP:WIND1:TABL:MEM ON" is sent to
a correct program message ":DISP:WIND1:TRAC1:MEM ON," the message sent is
received as an undefined command by this instrument. See the command reference and use
correct commands.
This error occurs also when a port not existing on this model is specified in a command
specifying a port number as an index. Such commands are
CALC:FSIM:SEND:DEEM:PORTn:xxxx, CALC:FSIM:SEND:PMC:PORTn:xxxx,
CALC:FSIM:SEND:ZCON:PORTn:Z0:R, and SENS:CORR:EXT:PORTn:TIME; they
include PORTn as a part.
34 User characterization not found in module
This error occurs when the selected user profile is not detected in the ECal memory, while
reading it from the ECal module, written by the user definition ECal.
V
30 Valid Ecal module not found
This error occurs when the number of ports of the ECal module connected is less than the
necessary number of ports. This error occurs, for example, when a 4-port Cal executing
command, SENS:CORR:COLL:ECAL:SOLT4, is executed with a 2-port ECal module
connected. This error is not generated by front key operations.
71 Valid power meter not found
Valid power meter is not connected (see Table 4-9 on page 209).
This error occurs when the E5070B/E5071B and the power meter is not connected with
USB/GPIB interface, the GPIB addresses do not match between the power meter and the
E5070B/E5071B's power meter, or the power meter is turned off, during the measurement
for power calibration data or for that in scalar-mixer calibration.
It also occurs when inoperable power meter is connected.
Ensure the connection of the power meter, GPIB addresses and power supply.
72 Valid power sensor not found
No valid sensor is connected to the power meter.
This error occurs when no power sensor is connected to the specified channel of the power
meter, during the measurement for power calibration data or for that in scalar-mixer
calibration.
