Pico 9302-25 – 25 GHz USB Sampling Oscilloscope

The PicoSample 3 workspace takes full advantage of your available display size and resolution. You decide how much space to give to the trace display and the measurements display, and whether to open or hide the control menus. The user interface is fully touch- or mouse-operable, with grabbing and dragging of traces, cursors, regions and parameters. There are enlarged parameter controls for use on smaller touch displays. To zoom, either draw a zoom window or use the more traditional dual timebase, delay and scaling controls.

A choice of screen formats

When working with multiple traces, you can display them all on one grid or separate them into two or four grids. You can also plot signals in XY mode with or without additional voltage-time grids. The persistence display modes use color-coding or shading to show statistical variations in the signal. Trace display can be in either dots-only or vector format.

Up to 25 GHz electrical bandwidth

The PicoScope 9300 series offers models at 15, 20 and 25 GHz with low sampling jitter and fine timing resolution to support measurement of transitions down to 14 ps (calculated). Among the fastest of all sampling oscilloscopes, the 9300 Series captures your waveform at up to 1 MS/s with timing resolution down to 64 fs and with 16-bit vertical resolution. It achieves lively trace, persistence and eye updates, greater than 60 dB dynamic range, and trace lengths up to 32 kS.

Trigger modes

• 2.5 GHz direct and up to 15 GHz prescaled trigger
  Sampling oscilloscopes accept their trigger from a separate input, either directly for repetition rates up to 2.5 GHz or via a prescaling divider input, for repetition rates up to 15 GHz (14 GHz on 15 and 20 GHz models).
• Built-in 11.3 Gb/s clock data recovery trigger
  To support serial data applications in which the data clock is not available as a trigger, or for which trigger jitter needs to be reduced, the PicoScope 9302 and 9321 include a clock recovery module. This continuously regenerates the data clock from the incoming serial data or trigger signal and can do so with reduced jitter even over very long trigger delays or for pattern lock applications. A divider accessory kit is included to route the signal to both the clock recovery and oscilloscope inputs.

Eye-diagram analysis

The PicoScope 9300 Series scopes quickly measure more than 30 fundamental parameters used to characterize non-return-to-zero (NRZ) signals and return-to-zero (RZ) signals. Up to ten parameters can be measured simultaneously, with comprehensive statistics also shown.

Pattern sync trigger and eye line mode

When a repeating data pattern such as a pseudorandom bit sequence is present, an internal trigger divider can lock to it. You can then use eye-line mode to move the trigger point, and view point, along the whole pattern, bit by bit.

Eye-line scan mode is also available to build an eye diagram from a user-selected range of bit intervals through to the whole pattern. These features are useful for analyzing data-dependent waveshapes.

Mask testing

PicoSample 3 has a built-in library of over 160 masks for testing data eyes. It can count or capture mask hits or route them to an alarm or acquisition control. You can stress test against a mask using a specified margin, and locally compile or edit masks.

There’s a choice of gray-scale and color-graded display modes to aid in analyzing noise and jitter in eye diagrams. There is also a statistical display showing a failure count for both the original mask and the margin. The extensive menu of built-in test waveforms is invaluable for checking your mask test setup before using it on live signals.

9.5 GHz optical model

The PicoScope 9321-20 includes a built-in precision optical-to-electrical converter. With the converter output routed to one of the scope inputs (optionally through an SMA pulse shaping filter), the PicoScope 9321-20 can analyze standard optical communications signals such as OC48/STM16, 4.250 Gb/s Fibre Channel and 2xGB Ethernet. The scope can perform eye- diagram measurements with automatic measurement of optical parameters including extinction ratio, S/N ratio, eye height and eye width. With its integrated clock recovery module, the scope is usable to 11.3 Gb/s.

The converter input accepts both single-mode (SM) and multi-mode (MM) fibers and has a wavelength range of 750 to 1650 nm.

TDR/TDT analysis

The PicoScope 9311 oscilloscopes feature built-in step generators for time-domain reflectometry and transmission measurements. The 9311-15 integrates a single rising step generator suited to single-ended TDR/TDT applications, while the 9311-20 features deskewable rising and falling step generators suited to single-ended and differential measurements. These features can be used to characterize transmission lines, printed circuit traces, connectors and cables with 16 mm resolution for impedance measurements and 4 mm resolution for fault detection.

The PicoScope 9311-15 and 9311-20 generate 2.5 to 7 V steps with 60 ps rise time from built-in step recovery diodes. They are supplied with a comprehensive set of calibrated accessories to support your TDR/TDT measurements, including cables, signal dividers, adaptors, attenuator and reference load and short.

The PicoScope 9311-20 TDR/TDT model includes source deskew with 1 ps resolution and comprehensive calibration, reference plane and measurement functions. Voltage, impedance or reflection coefficient (ρ) can be plotted against time or distance.

An alternative approach to TDR/TDT capability is to pair any 9300 Series scope with a standalone PG900 pulse generator. These instruments include similar differential step recovery diode step generators and also offer an option of 40 ps tunnel diode step generation. This brings extra flexibility and the ability to remotely position the pulse source. The generators also enable TDT and TDR with the PicoScope 9301, 9302 clock recovery, 9321 optical and 9341 4-channel sampling oscilloscopes.
