The PicoScope 9400 Series SXRTOs have four input channels up to 16 GHz with market-leading ADC, timing and display resolutions for accurately measuring and visualizing high-speed analog and data signals. They are ideal for capturing pulse and step transitions down to 22 ps, impulses down to 45 ps and clocks and data eyes to 8 Gb/s. Most high-bandwidth applications involve repetitive signals or clock-related data streams that can be readily analyzed by equivalent-time sampling (ETS).
The SXRTO quickly builds ETS, persistence displays and statistics. It has a built-in full-bandwidth trigger on every channel, with pretrigger ETS capture to well above the Nyquist sampling rate. There are three acquisition modes—real time, ETS and roll—all capturing at 12-bit resolution into a shared memory of 250 kS.
The PicoSample 4 software is derived from our existing PicoSample 3 and PicoScope 9000 products, which together represent over ten years of development, customer feedback and optimization.
The high-resolution display can be resized to fit any window, filling 4k and even larger monitors or arrays of monitors. Four independent zoom channels can show you different views of your data down to a resolution of 0.4 ps. Most of the controls and status panels can be shown or hidden according to your application, allowing you to make optimal use of the display area.
The oscilloscope has a 2.5 GHz direct trigger that can be driven from any input channel, and a built-in prescaler can extend the trigger bandwidth to 5 GHz. The external prescaler on the 9404-16 extends this further to 16 GHz.
These compact units are small enough to place on your workbench close to the device under test. Now, instead of using remote probe heads attached to a large benchtop unit, all you need is a short, low-loss coaxial cable. Everything else you need is built into the oscilloscope, with no expensive hardware or software add-ons to worry about, and we don’t charge you for new software features and updates.

High-bandwidth probes
The PicoConnect 900 Series low-impedance, high-bandwidth probes are ideal companions for the PicoScope 9400 Series, allowing cost-effective fingertip browsing of fast signals. Two series are available:
- RF, microwave and pulse probes for broadband signals up to 5 GHz (10 Gb/s)
- Gigabit probes for data streams such as USB 2, HDMI 1, Ethernet, PCIe and SATA
Other features
Bandwidth limit filters
A selectable analog bandwidth limiter (100 or 450 MHz) on each input channel can be used to reject high frequencies and associated noise. The narrow setting can be used as an anti-alias filter.
Frequency counter
A dedicated frequency counter shows signal frequency (or period) at all times, regardless of measurement and timebase settings, with a resolution of 1 ppm.
Optional clock and data recovery
Clock and data recovery (CDR) is now available as a factory-fitted optional trigger feature for the PicoScope 9404-16 and 9404-05 SXRTOs.
Associated with high-speed serial data applications, clock and data recovery will already be familiar to PicoScope 9300 users. While low-speed serial data can often be accompanied by a separate clock signal, at high speed this approach would create timing skew and jitter between the clock and the data that could prevent accurate data decoding.
Thus high-speed data receivers will generate a new clock, and using a phase-locked loop technique they will lock and align that new clock to the incoming data stream. This is the recovered clock, which can then be used to decode and thus recover data accurately. They have also saved the cost of an entire clock signal path by now needing only the serial data signal.
In many applications requiring our oscilloscopes to view the data, the data generator and its clock will be close at hand and we can trigger off that clock. However, if only the data is available (at the far end of an optical fiber, for instance), we will need the CDR option to recover the clock and then trigger off that instead. We may also need to use the CDR option in demanding eye and jitter measurements. This is because we want our instrument to measure as exactly as possible the signal quality that a recovered clock and data receiver will “see”.
When fitted, the PicoScope 9400 CDR option can be selected as the trigger source from any input channel. Additionally, for use by other instruments or by downstream system elements, two SMA(f) outputs present recovered clock and recovered data from the rear panel.
