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
