1. Changing of amplitude may add 0.5 ns.
2. Width accuracy specification is valid up to 5.5 Vpp amplitude. Above this amplitude, the width
will typically increase up to 300 ps.
Burst Count: 2 to 65536 (single or double
pulses).
Delay: Delay, phase or % of period.
Double pulse delay: Double pulse and
delay are mutually exclusive.
Duty cycle: Set between 0.1% and 95%
(subject to width limits. 99.9% with
overprogramming).
Transition times: These can be entered
as leading/trailing edge or % of width.
Leading and trailing edges are indepen-
dent within one of the following over-
lapping segments (1:20 ratio):
• 5 ns - 20 ns
• 10 ns - 200 ns
• 100 ns - 2 µs
• 1µs - 20 µs
• 10 µs - 200 µs
• 100 µs - 2 ms
• 1 ms - 20 ms
• 10 ms - 200 ms
Repeatability: Is typically four times better
than accuracy
Output timing fidelity: Period, delay and
width are continuously variable without
any output glitches or dropouts.
