Selections |

Edge |
Trigger on a rising, falling, or alternating edge of any source |
Pulse width |
Trigger when a positive- or negative-going pulse is less than, greater than, or within a specified range on any of the source channels.
Minimum pulse width setting:
5 ns (DSO501xA)
2 ns (DSO503xA, DSO505xA)

Pattern |
Trigger at the beginning of a pattern of high, low, and don't care levels and/or a rising or falling edge established across any of the channels, but only after a pattern has been established for a minimum of 2 nsec. The channel’s high or low level is defined by that channel’s trigger level. |
TV |
Trigger using any oscilloscope channel on most analog progressive and interlaced video standards including HDTV/EDTV, NTSC, PAL, PAL-M or SECAM broadcast standards. Select either positive or negative sync pulse polarity. Modes supported include Field 1, Field 2, all fields, all lines, or any line within a field. TV trigger sensitivity 0.5 division of sync signal. Trigger holdoff time can be adjusted in half field increments. |
Duration |
