DSP channel (optional)
6 dedicated computation channels (DSP channels) provided internal to the DL750/DL750P.
Performs realtime computation of addition, subtraction, multiplication, and division (with or without
coefficients), filtering, differentiation, integration, and knocking filtering using the 16 analog input
channels as computation sources. (For detailed specifications of the computation function of the
DSP channels, see section 19.5, “Function.”)
Below are the characteristics of the DSP channels
• The allocation of the acquisition memory of DSP channels is the same as analog input channels.
• Can be used in all acquisition modes.
• Can be set as a trigger source of simple triggers, the OR trigger of enhanced triggers, and
window triggers.
• Computed waveform can be displayed in realtime even during roll mode display.
• Can be used as a target waveform of cursor measurements and automated measurement of
waveform parameters.
• Can be used as a target channel for the dual capture function.
