EXT. I/O
EXT. I/O allows you to output the measurement complete signal and judgment results signal and to control the instrument by inputting signals such as
a measurement trigger signal. All signal lines are isolated from the instrument’s measurement and control circuitry for maximum noise resistance.

*: PARAx-HI, PARAx-IN, PARAx-LO, AND, BINx, OUT_OF_BINS
t1: From Comparator, BIN Judgement Result to EOM (LO): Setting value for delay time *1 (Settable range: 0.0000 s to 0.9999 s) ; 40 μs
t2: From EOM width (LO) to TRIG (LO): Minimum time from end of measurement to next trigger *2 ; 400 μs
t3: From TRIG (LO) to INDEX (HI): Time from trigger to circuit response *3 ; 400 μs
t4: INDEX width (HI): Analog measurement time (=Minimum chuck time), switching chuck with INDEX (LO) is possible *4 ; 1 ms
t5: EOM width (HI): Measurement time *4 ; 1.5 ms
t6: From TRIG width (LO) to LD-VALID (HI), CALIB (HI): Time to panel load execution and DC adjustment request signal detection: at least t3
t7: Trigger pulse width (LO time) ; At least 100 μs
t8: Trigger off (HI time) ; At least 100 μs
*1. There is an apporoximate error of 100 μs in the delay time entered for Judgement Result ↔ EOM for the setting value.
t1 is the reference value for when the setting value is 0.0000 s.
*2. t2 is the reference value for when trigger input for during measurement is disabled.
*3. Additional time is required when loading panel numbers using the panel load function.
*4. Reference value for Measurement frequency: 1 kHz, Measurement speed: FAST, Range: HOLD
