7.5 Operation
To use the handler interface, after setting up the handler interface board, setup the
limit table for using the comparator function or the list sweep setup table for using the
list sweep comparator function. Then set the handler interface to be enabled to
output/input the signals. The following procedures are for using the handler interface
with the comparator function or the list sweep comparator function.
7.5.1 Setting Procedure For Comparator Function
The following operation procedures are for using the handler interface with the
comparator function.
1) Set the measurement function, test frequency, oscillator signal level, and
measurement speed on the Meas Setup page.
2) Press the SETUP menu key, and the LIMIT softkey. The Limit Table will be
displayed.
3) Move the cursor to the FUNC field, and set if the parameter swap function is
used.
4) Move the cursor to the MODE field, and set the comparator limit mode: %TOL or
±TOL.
5) Move the cursor to the COMP field, and press softkey ON to enable the
comparator function.
6) Move the cursor to the AUX field. Press softkey ON to enable the AUX BIN,
then a device whose primary parameter is within limits, but whose secondary
parameter measurement result is not within limits will be sorted into an AUX BIN.
7) The EXT trigger mode is always be used, when a handler interface is used. Press
SETUP menu key, move the cursor to the TRIG field and set the trigger mode to
EXT. Check if the deviation display mode DEV_A/DEV_B is set to OFF.
8) Press DISPLAY menu key. To perform a measurement, select the LCR, BinNo,
COUNT softkey.
9) Comparator function are always used for sorting large amount of components
with the same nominal value, so range hold function may be used to increase the
measurement efficiency.
10) Move the cursor to the File field, use the SAVE softkey to save the current control
settings and limit table to a file.
7.5.2 Setting Procedure For List Sweep Comparator function
The following operation procedures are for using the handler interface with the list
sweep comparator function.
1) Set the measurement function, test frequency, oscillator signal level, and
measurement speed on the Meas Setup page.
2) The EXT trigger mode is always be used, when a handler interface is used. Press
SETUP menu key, move the cursor to the TRIG field and set the trigger mode to
EXT. Set deviation display mode DEV_A/DEV_B to ON if you want.
3) Press the SETUP menu key, and the LIST softkey. The List Setup page will be
displayed.
4) Setup a list table including sweep parameter points, parameter compared, and
high/low limits for the list sweep measurement.
5) Move the cursor to the MODE field, and set the sweep mode: SEQ or STEP.
6) Auto ranging always be selected, considering the delay time and source output
impedance.
7) Press DISPLAY menu key. To perform list sweep measurement, select the
SWEEP softkey.
8) Move the cursor to the File field, use the SAVE softkey to save the current control
settings and list table to a file.
