Troubleshooting R&S SMU200A

Normal action Error and error cause
On booting the instrument all calibration data
required must be written to the RAM of the
computer. The calibration data of a module is
either read from the EEPROM (in case of a cold
start from EEPROM only) or from the associated
binary file.
In case of a cold start, for each module identified
by the software a check is made first to determine
whether the EEPROM can be read.
If reading at the desired address is not possible,
the software assumes that the module is not
available. In this case an error message will be output:
“Missing Equipment”.
The software allows missing modules to be
simulated.
This means that after confirmation of the error
message the booting procedure is continued as if
everything were OK.
However, the instrument will then only function
partially or may even be completely unusable.
The simulation can indicate the following:
1: Software and front module controller are OK.
2: The defective module is most likely that which
caused an error message first. Subsequent errors
are possible (DACIF).
The calibration data stored in the EEPROM for
each module is then transferred to the controller
RAM.
A detailed error message is output if the
calibration data is not available or invalid.
Error message:
“EEPROM – missing Data”
“ ...(further details depending on module)”
Module only needs to be changed if factory
calibration data (preliminary module test) is missing
/ incorrect.
All other data can be obtained again by means of
internal adjustment or external calibration (see also
“
Troubleshooting with Internal Adjustments ”).
