4-Channel, 16-GHz Oscilloscope Grabs 22-ps Transitions

Jan. 28, 2020
The PicoScope 9404-16 boasts four high-resolution 12-bit channels driven by up to 5-TS/s (0.2 ps) equivalent-time sampling.

The PicoScope 9404-16, a 16-GHz sampler-extended, real-time oscilloscope (SXRTO) developed by Saelig Co., analyzes repetitive or clock-derived signals on four high-resolution 12-bit channels driven by up to 5-TS/s (0.2 ps) equivalent-time sampling (ETS). The wideband inputs accurately measure transitions as fast as 22 ps and pulses down to 45 ps wide, and permit clock performance and eye-diagram analysis of up to 11-Gb/s signals (to third harmonic).

In addition, the instrument’s real-time broadband sampling modes support analysis for other common RF signals, such as wireless frequencies of 900 MHz, 2.4 GHz, and 5.5 GHz. The SXRTO instrument architecture reduces the cost of broadband time-domain sampling for repetitive signal or clock-related applications.

In contrast to “sampling oscilloscopes,” the ETS technique supports trigger and pre-trigger capture and brings the familiarity, convenience, and ease of real-time oscilloscope operation. SXRTO technology seamlessly transitions to single-event, real-time waveform capture at sampling rates at and below 500 MS/s. Both sampling modes capture to memory of 250,000 samples (single channel). This is particularly valuable for the capture of slower system signals, modulation envelopes, and repeating pulse or data patterns, for example.

Compact enough to sit on the workbench in close proximity to the device under test (DUT), the USB-controlled PicoScope 9404-16 comes with PicoSample 4 software. A touch-compatible GUI controls the instrument and presents waveforms, measurements, and statistics on an attached PC display. It offers full support for available Windows display resolutions, allowing for the inspection of waveform detail or presentation of measurements on 4k monitors or projectors, or across multiple monitors.

A wide range of automated and user-configurable signal-integrity measurements, mathematics, statistical views, and limit-test facilities are included for validation and trending of pulse and timing performance, jitter, and return-to-zero and non-return-to-zero (RZ and NRZ) eye diagrams. Industry-standard communications mask tests such as PCIe, Gigabit Ethernet, and Serial ATA are included as standard. The PicoScope 9404 has an active SMA interface to support future configurations and accessories on this product architecture.
