13.6 Logic Inputs
13.6.1 Logic Input Unit
The 8804 has an internal logic input unit, which can
record a maximum of 8 channels of logic signals.
For operation details, refer to Section 5.2, "Basic Setting
Items of Each Function" and Chapter 11, "Trigger
Function."
･ The connections to the logic input section are on the right
side of th
e
8804.
･ Each logic probe can measure four logic signals (four
channels).
If no logic probe is connected, the corresponding logic
waveform is displayed on the waveform screen as high
level.
