Trigger and delay
Source Input A, B or External (via meter input) Input A, B, C or D
Modes Automatic Connect-and-View™, free run, single shot, edge, delay, dual slope,
video, video line, selectable pulsewidth (channel A only), N-cycle
Connect-and-View™Advanced automatic triggering that recognizes signal patterns, automatically sets up and continuously
adjusts triggering, time base and amplitude
Automatically displays stable waveforms of complex and dynamic signals like
motor drive and control signals
Can be switched off if preferred
Video triggering (on ch.A) NTSC, PAL, PAL+, SECAM; Includes field 1, field 2 and line select
High-res, non-interlaced video Non-interlaced video with line-select, for line frequencies in the range 14 kHz up to 65 kHz
Pulse width triggering
(on channel A)
Pulse width qualified by time
Allows for triggering <t, >t, =t, ≠ t, where t is selectable in minimum steps of 0.01 div or 50 ns
Time delay 1 full screen of pre-trigger view or up to 100 screens
(=1,200 divisions) of post-trigger delay
Dual slope triggering Triggers on both rising and falling edges alike
N-cycle triggering Triggers on N-th occurrence of a trigger event; N to be set in the range 2 to 99
