The Basic Real-Time Oscilloscope

The PicoScope 9404-05 CDR is a high-performance oscilloscope designed for engineers working with high-speed serial data and advanced signal analysis. This model is part of the 9400 Series and features Sampler-Extended Real-Time Oscilloscope (SXRTO) technology, combining real-time and equivalent-time sampling to deliver exceptional resolution and bandwidth.

With four input channels, the 9404-05 offers a 5 GHz analog bandwidth and supports real-time sampling at 500 MS/s per channel, as well as random equivalent-time sampling up to 1 TS/s, providing 1 ps resolution. It boasts a rise time of ≤70 ps, making it ideal for capturing fast transitions and fine signal details. The oscilloscope includes 12-bit ADCs, ensuring high vertical resolution and accurate signal representation.

The 9404-05 is also fitted with Clock and Data Recovery (CDR) capabilities, which has a clock recovery trigger data output of 6.5 Mb/s to 5 Gb/s and a frequency of half-full-rate clock output of 3.25 MHz to 2.5 GHz. CDR makes it especially valuable for applications in telecommunications, high-speed digital design, and compliance testing, where precise timing and synchronization are critical.

In addition, this SXRTO oscilloscope supports pulse, eye, and mask testing down to 45 ps and up to 11 Gb/s, enabling comprehensive signal integrity analysis. It includes a 250 kS trace length, shared across channels, and offers segmented memory with up to 1024 segments, allowing efficient capture of bursty or intermittent signals.

Its intuitive, touch-compatible Windows interface provides powerful tools for zooming, measurements, histograms, and data masks. With a compact USB-connected form factor, the PicoScope 9404-05 CDR delivers lab-grade performance in a portable package—ideal for both bench and field use.
