114 Chapter 9
Measurement Applications (Sample Programs)
Measurement with changing channels (scanning)
The program is detailed below.
Lines 80 to 90 Sets the GPIB address.
Lines 110 to 120 Assigns the number of measurements (10 times) and maximum
channel number to the Max_meas and Max_chan variables,
respectively
Lines 140 to 190 Assigns the setups of the primary parameter (Cp), secondary
parameter (D), measurement signal frequency (1 kHz), measurement
signal level (1 V), measurement time mode (short), and cable length (1
m) to the Pri$, Sec$, Freq, Lvl, Meas_time$, and Cbl variables,
respectively.
Lines 210 to 220 Assigns the limit range designation method (percent tolerance mode)
and reference value (1 nF) to the Mode$ and Nom variables,
respectively.
Lines 230 to 310 Assigns the lower limit values and upper limit values of BIN1 to BIN3
to the L_lim(*) and U_Lim(*) variables, respectively.
Lines 320 to 340 Assigns the lower limit value and upper limit value of the secondary
parameter limit range to the L_lim_sec and U_lim_sec variables,
respectively.
Lines 350 to 370 Assigns the ON/OFF state of the AUX BIN function, the ON/OFF
state of the Low C reject function, and the limit (10%) to the Aux$,
Low_c_rej$, and Low_c_rej_lim variables, respectively.
Line 390 Resets the instrument.
Lines 400 to 450 Sets the primary parameter, secondary parameter, measurement signal
frequency, measurement signal level, measurement time mode, and
cable length to Pri$, Sec$, Freq, Lvl, Meas_time$, and Cbl,
respectively.
Lines 470 to 480 Turns ON the MULTI compensation function and specifies the
channel-by-channel definition for the LOAD compensation standard
value.
Line 490 Sets the instrument to display the setup of the MULTI compensation
function in the instrument setup display area.
Lines 510 to 520 Turns OFF the beep sound output and locks the front panel keys.
Lines 560 to 760 Uses the FNCompen sub-program to measure the
OPEN/SHORT/LOAD compensation data for all of the channels (0 to
3). For the FNCompen sub-program, refer to the description in
Example 4-1 on page 40.
Line 780 Sets the measurement range to Nom.
Lines 820 to 830 Sets the limit range designation method and reference value to Mode$
and Nom, respectively.
Lines 840 to 870 Sets the lower limit values and upper limit values of BIN1 to BIN3 to
L_lim(*) and U_Lim(*) respectively and turns ON BIN1 to BIN3.
Lines 880 to 900 Turns OFF BIN4 to BIN9.
Lines 910 to 920 Sets the lower limit value and upper limit value of the secondary
parameter limit range to L_lim_sec and U_Lim_sec, respectively, and
