• The computed result of a DSP channel can be defined as a computation source of
another DSP channel. However, in this case, the computation delay is accumulated.
To avoid recursive reference in the computation, the channel that you can specify as
a computation source is a DSP channel with a smaller channel number than itself.
(Example: The selectable DSP channel on DSP channel 2 is DSP channel 1; the
selectable DSP channels on DSP channel 3 are DSP channels 1 and 2.)
• The computation delay is equal to 4 s the computation delay of the digital
filter. For details on the computation delay of the digital filter, see appendix 6.
• The range (Value/Div) of the DSP channel is automatically set to the optimum range
by evaluating the range value of the input source and the computing equation when
you press the Optimize Value/Div soft key. (However, since the range does not track
the input value or the computed result, you must adjust the Value/Div setting using the
V/DIV knob as described below.)
• You can change the range value (Value/Div) of the DSP channel using the V/DIV
knob.
• A total of 123 Value/Div ranges between 500.0E+18 and 10.00E–21 (1-2-5 steps) are
supported to accommodate the dynamic range of the computed result.
• The input and output of DSP channels are 16-bit binary data (if the input is 12 bits, it
is converted to 16 bits). For details on the internal processing, see "Computation
Flow and Internal Computation Format of DSP Channels" in appendix 6.
