To change the Vth measurement setup
You can EDIT the program to change the following parameters in the "Constant
Definition" block of the Meas_vth subprogram.
Parameter
Test_comm$
Comment for the measurement.
Param_file$
4155/4156 setup file to use.
Vth_max
The maximum Vth limit in V.
Vth_min
The minimum Vth limit in V.
Channel$
E5250A channel_list to use.
To change the E5250A input port/output port connections, change the Channel$
parameter. And if you want to change the E5250A connection functions (Channel
Configuration mode, etc.), modify the Set5250init subprogram.
To change the 4155/4156 measurement setup, change the Param_file$
parameter to the name of your desired setup file.
To change the name of parameter Vth entered from the 4155/4156, change VTH and
Vth to the desired name on the 3 lines shown below. Where VTH is the parameter
defined by the E5252.MES setup file.
