Instruction On The Use Of Handler Interface - East Tester ET3501 Operating Instructions Manual

ET35 Series Digital Bridges（LCR）Operating Instructions
VII. Instruction on the use of Handler
interface
ET35 digital bridge provides the user with Handler interface, which is mainly used for
the output of the sorting of the instrument. When the instrument is used in an automatic
component test system, the interface provides the signal to the system and the output of
the sorting results. Sorting results corresponds to the output of the comparator 10. The
design of Handler interface is flexible, and the states of all output signals are defined
according to the requirements for use after the use of different operating procedures.
Technical Description
The following table shows the technical description of Handler interface of ET35
Output signal: negative effective, open collector output, optoelectronic isolation
Level comparison function: Qualified level, tolerance level, and failed level
List sweep comparison function: IN / OUT at each sweep point and pass / fail of the
comparison results
INDEX: simulation measurement completed
EOM: primary measurement completed
Alarm: momentary power failure detection notification
Input signal: optoelectronic isolation
Keylock: front panel keypad locked
External trigger: pulse width ≧ 1uS
Instructions
Definition of signal line
HANDLER interface uses three signals: comparison output, control output and control
input. The signal lines of the level comparison function and List sweep comparison
function are respectively defined as different comparison output signal and control input
signal. The definition of the signals of the HANDLER interface is as follows when level
comparison function or List sweep comparison function is applied.
Signal line of comparison function
The signal line of comparison function is defined as follows:
Comparison output signal: / BIN1 - / BIN9, / AUX, / OUT, / PHI (primary

parameter is too high), / PLO (the main parameter is too low), / SREJ (auxiliary parameter
fails).
Control output signals: / INDEX (simulation measurement completion signal), /

EOM (compare data valid signal after the end of measurement), / ALARM (power failure
signal of the instrument).
Control input signal:

