Programs
Lines 510 to 630: When you finish connecting OPEN and press the
Continue key, measures phase and OPEN with the same
connection.
Lines 640 to 810: Measures SHORT and LOAD in the same way.
Lines 820 to 850: Calculates the setup data and saves it into the
nonvolatile memory.
Lines 880 to 1400 The Fixt_compen subroutine.
Lines 890 to 900: Waits until you connect the 16454A and press
the
Continue key.
Lines 920 to 970: Asks you if you want to execute fixture
compensation.
Lines 1000 to 1220: Obtains the setting values (the sweep range,
the sweep type, the signal source level, and the number of
measurement points) from user input.
Lines 1240 to 1310: Sets up the measurement conditions.
Lines 1320 to 1370: After you finish the connection for SHORT
measurement of the 16454A and press the
Continue key, SHORT
measurement is performed.
Lines 1420 to 1520 The Input_size subroutine. Sets the outside diameter, inside diameter,
and height of the MUT from user input.
Lines 1540 to 1750 The Sweep subroutine.
Lines 1550 to 1560: Waits until you insert an MUT into the
16454A and press the
Continue key.
Lines 1570 to 1630: Measures R and X.
Lines 1640 to 1720: Retrieves the measurement results and the
frequency setting and stores them into the R_data, X_data, and
Freq arrays.
Lines 1770 to 1920 The Calc subroutine. Using the R_data, X_data, and Freq arrays,
calculates the complex relative permeability and the loss tangent.
Lines 1950 to 2040 Sets the softkey labels and the subroutines to be executed when each
key is pressed. Then, waits until you press one of the softkeys.
Lines 2060 to 2270 Processing when the softkey labeled as “ur' - tan d” is pressed.
Displays the real part of the complex relative permeability (
) as
trace A and the loss tangent as trace B.
Lines 2290 to 2500 Processing when the softkey labeled as “|ur| - tan d” is pressed.
Displays the amplitude of the complex relative permeability
(
) as trace A and the loss tangent as trace B.
Lines 2520 to 2730 Processing when the softkey labeled as “ur' - ur'” is pressed. Displays
the real part of the complex relative permeability (
) as trace A and
the imaginary part of the complex relative permeability ( ) as trace
B.
