R38: Index register 1 for input data
The content of this register (default value: 0x0000) determines which date is shown in the process data
register
• DataIN0 [
}
51] of oscilloscope terminal KL3361
• DataIN0 (channel 1) [ } 51] or DataIN0 (channel 2) [ } 51] of oscilloscope terminal KL3362
The following indices are supported:
Index Decimal Date
0x0000 0 Current analog value
0x0001 1 Maximum value of a recording
0x0002 2 Minimum value of a recording
0x0003 3 RMS value of the recording: Sqrt((Sum (x
n
2
))/n
0x0004 4 Mean value of the recording: (Sum (x
n
))/n
0x0005 5 Peak-peak value of the recording
0x0006 6 Cycle duration
0x0007 7 Pulse width - high: switching threshold is trigger level 1
• The trigger starts as soon as four successive values are above the
switching threshold
• The trigger is stopped as soon as four successive values are below
the switching threshold
0x0008 8 Pulse width - low: switching threshold is trigger level 1
• The trigger starts as soon as four successive values are below the
switching threshold
• The trigger is stopped as soon as four successive values are above
the switching threshold

0x8000 First sampling value.
The recorded sampling values are available from here. The MSB has to
be set to zero in order to determine the trace offset.
0x8001 Second sampling value.
0x8002 Third sampling value.

0x8F9F Four thousandth sampling value (a maximum of 4,000 values can be
stored).
