Command 3: Sampling And Trigger Settings - Casio EA-200 Technical Reference

Command 3:
Sampling and Trigger Settings
{ 3, Sampling Interval, Number of Samples, Record Time, Trigger Source, Trigger
Threshold, Trigger Edge, Clock Source }
1. Sampling Interval (sec)
0.00002–0.0001: Fast sampling
0.0001–300: Normal sampling
300–16000: Extended sampling
This parameter is ignored when click edge is not timer.
2. Number of Samples
1 to 120000 Limited only by available memory.
–1 Sampled with each data request
Real-time (simultaneous) sampling
3. Record Time
0 None
1 Absolute time recording
2 Relative time recording
4. Trigger Source
0 None
Start sampling immediately upon receipt of Command 3.
1 [Start/Stop]
Start sampling when [Start/Stop] key is pressed.
2 CH1 Trigger
3 CH2 Trigger
4 CH3 Trigger
10 Microphone Trigger
11 SONIC Trigger
Start sampling in accordance with Motion Sensor (EA-2) sampled data.
Trigger monitor interval is in accordance with sampling interval.
12 SONIC Trigger
Same as 2–7.
20 Countdown
When [Start/Stop] key is pressed or when Command 8 is received,
countdown is performed by beeping at 1-second intervals the number of
times specified by count number, and then sampling starts.
–1 Wait for Command 8
When 1–12
Upon receipt of Command 8, sampling starts regardless of specified trigger
state.
