100 W) into the Load_l_lim and Load_u_lim variables, respectively.
Line 410 Resizes the Res array based on the value of the Nop variable.
Lines 450 to 460 Resets the instrument and sets the data transfer format to ASCII.
Lines 470 to 480 Sets the active table number to Act_tab and the unit of the signal
source level to Unit$.
Lines 490 to 530 Configures the measurement point setup table.
Line 540 Turns on list measurement.
Lines 560 to 580 Sets measurement parameters 1 through 4 to Para$(1) through
Para$(4).
Line 620 Configures the instrument to use the 4287A Option 007 (16195B 7-
mm calibration kit).
Lines 640 to 750 Passes control to a subprogram named FNCal, which measures the
data for the OPEN, SHORT, LOAD, and LOW LOSS CAPACITOR
standards. For more information on the FNCal subprogram, refer to
the description in Example 4-1 on page 46.
Lines 770 to 790 Calculates the calibration coefficients and turns on the calibration
function.
Line 840 Passes control to a subprogram named Set_fixture, which configures
the test fixture. For more information on the Set_fixture subprogram,
refer to the description in Example 4-2 on page 60.
Line 860 Configures the 4287A to use its built-in definition for the
compensation kit value.
Lines 890 to 940 Passes control to a subprogram named FNCompen, which measures
the OPEN and SHORT data. For more information on the FNCompen
subprogram, refer to the description in Example 4-2 on page 60.
Lines 960 to 980 Calculates the compensation coefficients and turns on the
compensation function.
Lines 1020 to 1030 Sets the trigger source to GPIB/LAN trigger and turns on the
continuous activation of the trigger system.
Lines 1080 to 1090 Prompts the user to connect a DUT and waits for a press of the
[Enter]
key after the connection.
Lines 1130 to 1180 Triggers the instrument after the trigger system is put into Waiting for
Trigger state, and then retrieves the measurement results.
Lines 1220 to 1290 Displays the measurement results.
Lines 1310 to 1320 Prompts the user to choose whether to perform a measurement again.
If the user presses the
[y] key and [Enter] key, the program returns to
the DUT connection part to repeat measurement.
