Typical Application
Most signals.
High-frequency 5 V logic signals. (The dc-coupling of the L function can
attenuate high-frequency logic signals, reducing their amplitude enough to
interfere with triggering.)
Refer to the measurement tips given on page 27.
5 V logic signals (TTL).
Automotive switching signals.
Refer to the measurement tips given before on page 27.
AC current signals.
Refer to the measurement tips given before this table.
