25 GHz bandwidth in a compact USB instrument
PicoScope 9300 Series sampling oscilloscopes use triggered sequential sampling to capture high-bandwidth repetitive or clock-derived signals without the expense or jitter of a very high-speed clocked sampling system such as a real-time oscilloscope. 25 GHz bandwidth allows measurement of 14 ps transitions, and low sampling jitter enables timing resolution down to 0.064 ps. Sequential sampling rate of 1 MS/s, unsurpassed by any other sampling oscilloscope, enables rapid building of waveforms, eye diagrams and histograms with 16-bit resolution. Dynamic is better than 60 dB and trace lengths can be up to 32 kS.
These two- and four-channel units occupy very little space on a workbench and are small enough to carry with a laptop for on-site testing. Furthermore, instead of using remote probe heads attached to a large benchtop unit, you can position the PicoScope 9300 right next to the device under test and connect to it with short, low-loss coaxial cables.
Everything you need is built into the oscilloscope, with no expensive hardware or software add-ons to worry about. Alternatively, you can use your PicoScope 9300 with a stand-alone PG900 TDR/TDT differential fast pulse generator to gain the extra versatility and configurability of independent high-performance source and measurement instruments.

Triggers and clock data recovery (CDR)
2.5 GHz direct and 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 14 GHz (on 20 GHz models), 15 GHz (on 25 GHz models).
100 MHz internal direct trigger
The 9300 scopes are equipped with a built-in internal direct trigger from each channel for signals up to 100 MHz. This full-function trigger also provides level, slope, hysteresis and holdoff controls.
Built-in 11.3 Gb/s clock data recovery (CDR)
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.
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.
The PicoScope 9311 and 9312 scopes include a built-in deskewable differential step generator for time-domain reflectometry (TDR) and time-domain transmission (TDT) measurements. This feature 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 9312 is supplied with external tunnel diode pulse heads that generate positive and negative 200 mV pulses with 40 ps system rise time. The PicoScope 9311 generates large-amplitude differential pulses with 60 ps system rise time directly from its front panel and is suited to TDR/TDT applications where the reflected or transmitted signal is small.
The PicoScope 9300 Series TDR/TDT models include 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.
The PicoScope 9311 and 9312 are supplied with a comprehensive set of calibrated accessories to support your TDR/TDT measurements. These include cables, signal dividers, adaptors, an attenuator and reference load and short.
Optional 9.5 GHz optical input
The PicoScope 9321 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 can analyze standard optical communications signals such as OC48/STM16, 4.250 Gb/s Fiber 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 multimode (MM) fibers and has a wavelength range of 750 to 1650 nm.
SMA Bessel-Thomson pulse-shaping filters
A range of Bessel-Thomson filters is available for standard frequencies. These filters are essential for accurate characterization of signals emerging from an optical transmission system. The first eye diagram, above left, shows the ringing typical of an unequalized O/E converter output at 622 Mb/s. The second eye diagram, above right, shows the result of connecting the 622 Mb/s B-T filter. This is an accurate representation of the signal that an equalized optical receiver would see, enabling the PicoScope 9321 to display correct measurements.
The PicoScope 9341 and 9341-25 sampling oscilloscopes offers 20 to 25 GHz bandwidth on four channels for engineers who need to characterize performance of multi-lane gigabit transmission systems, and check for channel-to-channel interference and compatibility.
Sequential time sampling (STS) mode
The oscilloscope samples after each trigger event with a regularly incrementing delay derived from an internal triggerable oscillator. Jitter is 1.8 ps typical, 2.0 ps maximum. The 1 MS/s sampling rate, the highest of any sampling scope, builds waveforms and persistence displays faster.
A variation of STS mode in which sampling is controlled by the external prescaled trigger. Jitter is reduced, even with long time delays.
The oscilloscope acquires one sample per internal trigger, independent of timebase settings. The delay is generated by a precise internal clock oscillator.
Real-time, random equivalent time sampling and roll modes
Uniquely, there is a 100 MHz bandwidth trigger pick-off within the samplers. The PicoScope 9300 scopes can therefore operate similarly to a traditional DSO in roll, transient capture and ETS modes. Signals up to 100 MHz are conveniently displayed without the need for another oscilloscope.
Built-in signal generator
The scope can generate industry-standard or custom signals including clock, pulse and pseudorandom binary sequence. These can be used to test the instrument’s inputs, experiment with its features and verify complex setups such as mask tests. AUX OUTPUT can also be configured as a trigger output.
Configure with the PG900 external fast pulse source
For greater versatility than a built-in signal generator can offer, you may want to separate your high-performance fast-step TDR/TDT pulse source from the sampling oscilloscope and have two instruments to use either stand-alone or together as required. The PicoSource PG900 Series differential pulse generators use the same fast-pulse source as the PicoScope 9311 and 9312, rehoused in a separate USB-controlled instrument, and are supplied with PicoSource PG900 control software.
Choose from three models:
- PicoSource PG911 with integrated 60 ps pulse outputs
- PicoSource PG912 with 40 ps pulse tunnel diode heads
- PicoSource PG914 with both types of output
