Pulse parameter measurements
The PicoScope 9200A scopes
quickly measure over 40 pulse parameters, so you don’t need to count
graticules or estimate the waveform’s position. Up to ten simultaneous
measurements or four statistics measurements are possible. The measurements
conform to the IEEE standards.
Optical-to-electrical converter
The PicoScope 9221A and 9231A
have a built-in 8 GHz’ optical electrical converter. This allows analysis
of optical signals such as SONET/SDH OC1 to OC48, Fibre Channel FC133
to FC4250, and G.984.2. The converter input accepts both single-mode
(SM) and multimode (MM) fibers and has a wavelength range of 750 to
1650 nm.
A selection of Bessel-Thomson
filters can be purchased separately for use with specific optical standards.
Powerful mathematical analysis
The PicoScope 9000 Series
supports up to four simultaneous mathematical combinations and functional
transformation of acquired waveforms.
You can select any of the
mathematical functions as a maths operator to act on the operand or
operands. A waveform maths operator is a maths function that requires
either one or two sources. The operators that involve two waveform sources
are: Add, Subtract, Multiply, and Divide. The operators that involve
one waveform source are: Invert, Absolute, Exponent, Logarithm, Differentiate,
Integrate, Inverse, FFT, Interpolation, Smoothing.
Histogram analysis
A histogram is a probability
distribution that shows the distribution of acquired data from a source
within a user-definable histogram window. The information gathered by
the histogram is used to perform statistical analysis on the source.
Histograms can be constructed
on waveforms on either the vertical or horizontal axes. The most common
use for a vertical histogram is measuring and characterising noise on
displayed waveforms, while the most common use for a horizontal histogram
is measuring and characterising jitter on displayed waveforms.
Eye-diagram analysis
The PicoScope 9000 Series
quickly measures more than 30 fundamental parameters used to characterise
non-return-to-zero (NRZ) signals and return-to-zero (RZ) signals. Up
to four parameters can be measured simultaneously.
The PicoScope 9211A, 9221A
and 9231A also include a 10 Gbps software pattern sync trigger for averaging
eye diagrams.
Mask testing
For eye-diagram masks, such
as those specified by the SONET and SDH standards, the PicoScope 9000
Series supports on-board mask drawing for visual comparison. The display
can be grey-scaled or colour-graded to aid in analysing noise and jitter
in eye diagrams. Over 150 industry-standard masks are included.
FFT analysis
All PicoScope 9000 Series
oscilloscopes can perform up to 2 Fast Fourier Transforms of input signals
using a range of windowing functions. FFTs are useful for finding crosstalk
problems, finding distortion problems in analog waveforms caused by
non-linear amplifiers, adjusting filter circuits designed to filter
out certain harmonics in a waveform, testing impulse responses of systems,
and identifying and locating noise and interference sources.
Pattern sync trigger and
eye line mode
The PicoScope 9211A, 9221A
and 9231A can internally generate a pattern sync trigger derived from
bit rate, pattern length, and trigger divide ratio. This enables it
to build up an eye pattern from any specified bit or group of bits in
a sequence.
Eye line mode works with the
pattern sync trigger to isolate any one of the 8 posssible paths, called
eye lines, that the signal can make through the eye diagram. This allows
the instrument to display averaged eye diagrams showing a specified
eye line.
TDR/TDT Measurement and Analysis (9211A & 9231A
only)
The PicoScope 9211A and 9231A
TDR/TDT Oscilloscopes are specially designed for time-domain reflectometry
(TDR) and time-domain transmissometry (TDT). It provides a low- cost
method of testing cables, connectors, circuit boards and IC packages
for unwanted reflections and losses.
The PicoScope 9211A and 9231A
work by launching pulses into the device under test using one of their
two independently programmable, 100-ps rise-time step generators. They
then use their 12 GHz sampling inputs to build up a picture from a sequence
of reflected or transmitted pulses. The results can be displayed as
volts, ohms or rho against time or distance.
