Digital logger clock
Rates	Log rate: 1 second to 1 hour in 1 second steps
Stability	Logger timing obtained from PC
Post Trigger Delay	Depending on sampling frequency; 500MHz: maximum delay = 131 us 200MHz: maximum delay = 10 ms 1MHz: maximum delay = 16 sec 2.5kHz: maximum delay = 6710 sec Accuracy: 5 x sampling period.

Trigger conditions
Pattern	"1", "0" and "don’t care" conditions selectable on all channels
Edge	On any channel. Rising edge, falling edge, or change-of-state
Edge/Pattern combinations	edge up, edge down, edge up OR edge down (change-of-state) pattern pattern OR edge up/edge down/change-of-state pattern AND edge up/edge down/change-of-state pattern THEN edge up/edge down/change-of-state edge up/edge down/change-of-state THEN pattern pattern < duration (glitch capture). Duration ±20ns tolerance, 1 ms max. pattern > duration. Duration ±20ns tolerance, 1 ms max.
