Keysight N5990A MIPI M-PHY Receiver Test User Guide
SetToDefault()
After the Connect() call, the implementation should set all instruments
with initial values to set default values. It is recommended that the
sequence is stated with nominal values to ensure that the test setup is
done properly. With this setting, the first run will be done and the Init()
call will not overwrite the values.
Init()
The function is used to initialize the instruments with start values at the
beginning of test sequence.
GetParameterList() and GetParameterValues()
These functions are used to get the parameter names and values lists and
put them into the result output of each test procedure.
SetNextValue()
If this function returns true at the end of each run over the selected test
procedures, N5990A will run the selected tests again. This function should
get the next parameter set, set the controlling instruments, and return true
if a new set of parameters is available.
Example:
For a sweep over temperature starts at 20 °C, increasing the temperature
by 2 °C at each run, and ending at 40 °C, the function should increase the
temperature of the chamber and return true if 40 °C is not reached. If the
next step is greater than 40 °C, this function should return false. N5990A
will end the test sequence in this case.
Disconnect()
It is called at the closing of N5990A. The driver should set the instruments
to default values and disconnect from the instruments. An sample project
is available on the Keysight webpage.
