03 | Keysight | N2806A Calibration Pulse Generator. The world’s fastest differential pulse generator – Data Sheet
The New Calibration and Metrology Standard
As the fastest, highest spectral purity, differential pulse generator, the N2806A is the new
standard in demanding calibration and metrology environments.
The new standard for calibration and rise time in
oscilloscopes and other electronic equipment.
As oscilloscopes like Keysight’s 90000 Q-Series and other
electronic equipment exceed 40 GHz of bandwidth, a pulse
generator is needed that can keep up. Enter the N2806A.
Boasting 10%-90% rise and fall times less than 9 ps and
7 ps respectively, this source can produce high frequency
content beyond 60 GHz.
With its near ideal spectral content and fully differential
output, the N2806A is the new standard for electronic
equipment calibration and rise time measurements.
The new standard in step response measurements and
demanding metrology applications.
When characterizing the step response of a device or system,
you need the step impinging on your device to approximate
an ideal step as closely as possible. The N2806A boasts the
fastest and highest spectral purity step available. Compare
the performance of the N2806A versus another common high
speed pulse generator in the deviation from an ideal step
plot at the right. Notice how smoothly the N2806A rolls off
compared to the resonances in frequency content from the
other generator.
Using the close-to-ideal step of the N2806A, you know
you can trust your step response results to be accurate
and repeatable
Plot of deviation from an ideal step for Keysight N2806A, dark blue
(magnitude) and dark red (phase), versus popular shock line based
generator, bright blue (magnitude) and bright pink (phase). Notice
the purity of the spectral content for the Keysight generator, much
more closely approximating an ideal step for more accurate and
repeatable measurements. Plot is generated by taking the FFT
of the impulse response of each generator. Impulse response is
simply the time derivative of the step response.
