Product overview The PicoScope 9400 Series sampler-extended real-time oscilloscopes (SXRTOs) have two or four high-bandwidth 50 Ω input channels 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, impulse down to 45 ps, and clocks and data eyes to 11 Gb/s (with optional 5 or 8 Gb/s clock recovery). The PicoScope SXRTOs offer random sampling, which can readily analyze high-bandwidth applications that involve repetitive signals or clock-related...

Random sampling Trigger modes PicoScope 9400 Series SXRTOs use random sampling to capture high-bandwidth repetitive or clock-derived signals without the expense or jitter of a very high-speed real-time oscilloscope. Simply feed your signal into one of the input channels. On the 16 GHz model transition time is 22 ps and on the 5 GHz model 70 ps, both typically faster than competing equivalent bandwidth models. Random sampling enables timing resolution down to 0.4 ps and 1 ps respectively. The oscilloscopes have a DC to 2.5 GHz internal direct trigger from each input channel and 5 GHz from each...

Clock and data recovery Bandwidth limit filters Clock and data recovery (CDR) is now available as a factoryfit optional trigger feature on all models. A selectable analog bandwidth limiter (100 or 450 MHz, model-dependent) 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 in real-time sampling modes. 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 its clock as a separate signal,...

Segmented acquisition mode Channel deskew Segmented acquisition mode in the Acquire menu partitions the available trace memory length into multiple trace lengths (segments or buffers). Up to 1024 traces can then be captured and either layered or individually selected to display on screen. This is helpful for capturing and viewing rarely occurring events. The deskew variable adjusts the horizontal position (time offset) of one active channel with respect to another on the instrument display. The deskew function has a ±50 ns range. Coarse increment is 100 ps, fine increment is 10 ps. With manual...

SXRTO explained The basic real-time oscilloscope Real-time oscilloscopes (RTOs) are designed with a high enough sampling rate to capture a transient, non-repetitive signal with the instrument's specified analog bandwidth. This will reveal a minimum width impulse, but is far from satisfactory in revealing its shape, let alone measurements and characterization. Typical high-bandwidth RTOs exceed this sampling rate by perhaps a factor of two, achieving up to four samples per cycle, or three samples in a minimum-width impulse. Random sampling For signals close to or above the RTO's Nyquist limit,...

Display area View live, reference and math waveforms. Drag waveforms to reposition them and drag or draw zoom windows. You can drag markers, bounds and thresholds to configure measurements on the screen. On-screen controls can be hidden to increase trace area. System controls Select whether the oscilloscope is running or stopped. Other buttons allow you to reset the oscilloscope to default status, Autoscale or erase waveforms from the display. Status area Displays acquisition status, mode and number of acquisitions. Also trigger status, date, time and a quick reference to record length and horizontal...

Waveform measurements with statistics Standard waveforms and eye parameters Waveform parameters can be measured in both X and Y axes including X period, frequency, negative or positive cross and jitter. In the Y axis measurements such as max, min, DC RMS and cycle mean are available. Measurements can be within a single trace or trace-to-trace such as phase, delay and gain. The PicoScope 9400 Series oscilloscopes quickly measure well over 40 standard waveforms and over 70 eye parameters, either for the whole waveform or gated between markers. The markers can also make on-screen ruler measurements,...

Eye diagram measurements The PicoScope 9400 Series scopes quickly measure more than 70 fundamental parameters used to characterize non‑return‑to‑zero (NRZ) signals and return-to-zero (RZ) signals. Eye diagram analysis can display data including: bit rate, period, crossing time, frequency, eye width, eye amplitude, mean, area and jitter RMS. Also shown on the graph are left and right RMS jitter markers. These measurements are selectable from within the Eye Diagram side menu and are listed on screen below the graph. The measurement points and levels used to generate each parameter can optionally...
