± 5 % of scale Most signals.
K
600 mV ± 30 mV 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.)
mL

L
6 V 1.7 V 5 V logic signals (TTL).
L
60 V 4 V Automotive switching signals.
