PicoScope 9404A-25 and 9404A-25 CDR Sampler-Extended Real-Time Oscilloscopes

On July 1, 2025, Pico released new models in the 9400A series, which have been added to the existing range.

Pico Technology launches the new PicoScope 9404A-25 and 9404A-25 CDR SXRTO sampler-extended real-time oscilloscopes with 25 GHz bandwidth, 14 ps transition time and 5 TS/s (0.2 ps resolution) random sampling.

Series 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 14 ps, impulse down to 28 ps, and clocks and data eyes up to 16 Gb/s (with optional 11.3 Gb/s clock recovery).
The PicoScope SXRTOs offer random sampling, which can readily analyze high-bandwidth applications that involve repetitive signals or clock-related streams.
The SXRTO is fast: random sampling, persistence displays and statistics all build quickly.
The PicoScope 9400 Series has a built-in internal trigger on every channel, with pre-trigger random sampling to well above the Nyquist (real-time) sampling rate. Bandwidth is up to 25 GHz behind a 50 Ω 2.92 mm (K) female (compatible with SMA) input, and three acquisition modes-real-time, random and roll-all capture at 12-bit resolution into a shared memory of up to 250 kS.
The touch-compatible PicoSample 4 software embodies over ten years of development, customer feedback and optimization.
The display can be resized to fit any window and fully utilize available display resolution, 4K and even larger or across multiple 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.
A 2.5 GHz direct trigger can be driven from any input channel, and a built-in divider can extend the off-channel trigger bandwidth to 5 GHz. On the 16 and 25 GHz models a further external prescaled trigger input allows stable trigger from signals from 16 to 20 GHz bandwidth and, from the internal triggers, recovered clock trigger is available (if optional clock recovery is fitted) at up to 11.3 Gb/s. With this option, recovered clock and data are both available on SMA outputs on the rear panel.
The price you pay for your PicoScope SXRTO is the price you pay for everything - we don't charge you for software features or updates.

Typical applications
These oscilloscopes are designed for engineers working both in research laboratories and in production environments, and who, above all, need characteristics associated with flexible measurements of wide-bandwidth signals:

• Telecom and radar test, service and manufacturing
• Optical fiber, transceiver and laser testing (optical to electrical conversion not included)
• RF, microwave and gigabit digital system measurements
• Signal, eye, pulse and impulse characterization
• Precision timing and phase analysis
• Digital system design and characterization
• Eye diagram, mask and limits test up to 16 Gb/s
• Clock and data recovery at up to 11.3 Gb/s
• Ethernet, HDMI 1, PCI, SATA and USB 2.0
• Semiconductor characterization
• Signal, data and pulse/impulse integrity and pre-compliance testing

PicoScope 9404A models: inputs, outputs and indicators

9404A-25 front panel

Power/status/trigger LED: Green under normal operation. Also indicates connection progress and trigger.
Channel inputs: CH1 to CH4. You can enable any number of channels without affecting the sampling rate; only the capture memory (250 kS) is shared between the enabled channels.
EXT IN: External direct trigger (up to 5 GHz)
PRESCALE: 20 GHz external prescaled trigger
TRIGGER OUT: Can be used to synchronize an external device to the PicoScope 9404A's rising edge, falling edge and end of holdoff triggers.

USB: The USB 2.0 port (also compatible with USB 3.0) is used to connect the oscilloscope to the PC. If no USB host is found, the oscilloscope tries to connect through the LAN port.
LAN: LAN settings must be supplied initially by connecting to the USB port. Once configured, the oscilloscope uses the LAN port if no USB host is detected.
One of up to eight PicoScope 9400 units can be addressed from the PicoSample 4 software.
CLK & DATA: Recovered clock and data from the currently selected trigger source and the built-in clock recovery module (optional).
12 V DC: Power input. Use only the earthed mains adaptor supplied with the oscilloscope.
