Vth and Capacitance Measurement Program

To output the measurement report to printer

You can EDIT to change the following parameters in the Init_setting subprogram. Printer must be connected to computer by using GPIB cable. The report as shown in example in Figure 9-2 will be printed automatically.

Parameter	Description	Default

Ad_prn	GPIB address for printer	1

Prn_enab	Enable/disables print out function.	0
	(1: Enable, 0: Disable)

To execute the 4155/4156 calibration

Remove the exclamation marks from program lines. These lines are in Init_instrument done automatically before measurement.

lines shown below, and enter the subprogram. The calibration will be

!CALL Cal415x

!DISP "Agilent 4155/4156 Calibration Completed"

To save the 4155/4156 measurement data

To save the Vth measurement data to a diskette in the 4155/4156's disk drive, remove the exclamation marks from the program lines shown below, and enter the lines. These lines are in the "Save Measurement Data" block of the Meas_vth subprogram.

!OUTPUT @Hp415x;":MMEM:STOR:TRAC DEF,'VTH.DAT','DISK'"

!OUTPUT @Hp415x;"*OPC?"

!ENTER @Hp415x;A

The measurement data will be saved to the VTH.DAT file after the measurement. If desired, you can use another file name instead of VTH.DAT.
