Measured over central 8 div
Input coupling of channel and
coupling of MTB trigger are
cascaded
Coupling switch in DC position
Coupling switch in AC or AC-LF

Coupling switch in DC position
Coupling switch in AC-LF position
Up to 50 kHz
Line trigger derived from mains
Time-base starts when trigger
occurs
Same as TRIG, but bright baseline
is displayed if during 0,1 s no
trigger has occurred
Same as TRIG, but only for first
time after SINGLE has been
activated and after RESET
Approx. 10 Hz (— 3 dB)
Bandpass: approx.
10 Hz...15 kHz (— 3 dB)
TVF: 0,5 s/div...0,1 ms/div
