Programs
Lines 770 to 810: Passes control to a subprogram named Inp_data,
which obtains the definition values for the load (working standard)
from user input. For more information on the Inp_data
subprogram, refer to the description in Example 4-1 on page 46.
Lines 850 to 910 Passes control to a subprogram named FNCal to measure the OPEN
data for calculating the calibration coefficients for all of the required
tables (1 to Max_tab_no) in the order of table number. For more
information on the FNCal subprogram, refer to the description in
Example 4-1 on page 46.
Lines 930 to 990 Passes control to a subprogram named FNCal to measure the SHORT
data for calculating the calibration coefficients for all of the required
tables (1 to Max_tab_no) in the order of table number.
Lines 1010 to 1070 Passes control to a subprogram named FNCal to measure the LOAD
data for calculating the calibration coefficients for all of the required
tables (1 to Max_tab_no) in the order of table number.
Lines 1090 to 1140 For all of the required tables (1 to Max_tab_no), calculates the
calibration coefficients and turns on the calibration function in the
order of table number.
Lines 1180 to 1190 After the trigger system is stopped (turning off the continuous
activation of the trigger system), the program sets the trigger source to
External trigger.
Lines 1240 to 1390 Iterates the following steps Meas_max times.
1. Line 1250: Displays the message that prompts you to connect a
DUT.
2. Lines 1260 to 1310: For all of the required tables (1 to
Max_tab_no), iterates the following steps in the order of table
number.
a. Displays the message that prompts you to set an appropriate
channel of the scanner, specifies the active table, and executes
the :READ? command.
b. Prompts the user to input an external trigger after the
/READY_FOR_TRIG signal of the handler interface changes
to Low level. The program waits until the instrument receives
an external trigger and completes the measurement cycle.
c. Retrieves the measurement result.
3. Lines 1320 to 1380: Determines bins based on whether the
measurement results (Ls) for all channels fall between L_lim and
U_lim and displays the classified bins.
Lines 1430 to 1490 Displays the results of the measurements repeated Meas_max times
and bin sorting.
