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.
This error occurs when the E5071C and the power meter is not connected with
USB/GPIB interface, the GPIB addresses do not match between the power
meter and the E5071C'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.
Ensure the connection of the power sensor.
75 Valid signal generator not found. No valid external signal source is
connected
This error occurs when the specified type of external signal source is not
connected to the specified GPIB address, though the control of the external
signal source is enabled (SENS:OFFS:LOC:STAT ON and
SENS:OFFS:LOC:CONT ON).
It also occurs when USB/GPIB interface is set but not connected.
Ensure the external signal source and the connection of USB/GPIB interface.
