The FemtoFiber
®
pro is equipped with many sensors, helping to constantly monitor the system health and
to identify problems. There are a few commands which generate debugging outputs to analyze a
potential problem and to support our service staff.
Selftest
ffpro.selftest() (command, 1 optional parameter)
Performs a automatic selftest of the laser hardware.
parameter: (optional)
_ comma separated list of verbosity modes, and test names
Use ffpro.selftest("?") to get a list of available options on your system.
Example:
>>> ffpro.selftest(“basic”)
....
0
>>>
to do a quick basic selftest, checking fundamental operation of most of the hardware components. The
command will report the different steps of the selftest. In case of problems with one of the components a
“FAIL” is reported together with the source of the problem. In the last line of the command output the
total number of “FAILs” is reported. This basic test is non-invasive and should not disturb the current laser
emission.
A more detailed selftest is done by using the command
>>> ffpro.selftest(“complete”)
....
0
>>>
In addition to the basic test, some more complicated and time consuming measurements are done,
such as motor referencing, pump diode analysis etc. During these tests the laser emission is switched OFF
and the motor is moved.
In standard mode the selftest commands only reports failures. A more detailed output is available in
verbose mode, by adding a “,v” to the parameter:
>>> ffpro.selftest(“complete,v”)
....
0
>>>
In this mode a detailed list with all executed tests is reported. It can be a very useful source of information
for our service staff in case of problems.
