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 inde-

pendent within one of the following

overlapping 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.

Output timing fidelity: Period, delay, and

width are continuously variable with-

out any output glitches or dropouts.

Repeatability: Is typically four times

better than accuracy.

Double pulse delay range (width + 10.0 ns) to

(period - width - 10.0 ns)

Accuracy ± 5% ± 500 ps

Transition time range (10/90) 5 ns to 200 ms variable

Accuracy ± 10 % ± 200 ps

[1] If the startable oscillator (VCO) is used (PLL not active).

[2] Changing of amplitude may add 0.5 ns.

[3] Width accuracy specification is valid up to 5.5 Vpp amplitude. Above this amplitude, the width will typically

increase up to 300ps.

Specifications

Specifications describe the instrument’s warranted performance. Non-

warranted values are described as typical. All specifications apply after a

30-minute warm-up phase with 50 Ω source/load resistance and separate

channels. All specifications are valid from 0°C to 55°C ambient temperature.

Timing Characteristics

Measured at 50% amplitude at fastest transitions, in continuous mode,

and 50 Ω source impedance.
