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.
