The last 3.5 M data points (recording time for one analog channel)
are stored in internal memory.
Data retained in memory can be observed by backward scrolling.
Basic Specifications
Trigger Section
Trigger method
Digital comparison
Trigger timing
Start, stop, start&stop
Trigger source
Analog input (CH1 to 10), Integrated pulse input (P1 to 4)
External trigger
Triggering occurs when the external trigger and ground terminals
are shorted, or on falling edges from High (3 to 5 V) to Low (0 to 0.8
V) levels.
Maximum input voltage: 0 to 7 V DC
Minimum response pulse width: 1 ms H, 2
s L
Trigger criteria
AND or OR of each trigger source, Trigger criteria can be set for
each channel.
Trigger types
(analog and pulse)
• Level Trigger
Triggering occurs when the signal rises (or falls) through a
specified value.
• Window Trigger
Triggering occurs when the input signal level enters or exits the
amplitude window defined by upper/lower thresholds.
Trigger level
resolution
Analog channel: 0.025%f.s. (f.s. = 10 divisions)
Pulse channel: 1c (Pulse count integration), 1/n r/s (revolution)
n = pulses/revolution
Pre-trigger
Time span setting (any span). Settable with real-time saving.
