PicoScope 9400 Series Datasheet

The PicoScope 9400 Series (9402-05, 9402-16, 9404-05, 9404-16) SXRTOs are a new class of oscilloscopes that combine the benefits of real-time sampling, random equivalent-time sampling and high analog bandwidth.

The PicoScope 9400 Series sampler-extended real-time oscilloscopes (SXRTOs) have two or four high-bandwidth 50 O 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 100 ps, and clocks and data eyes to 8 Gb/s (with optional clock recovery).

The SXRTO is fast, with quick generation of random sampling waveforms, persistence displays and statistics. 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 16 GHz behind a 50 O SMA(f) 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.

Random sampling

For signals close to or above the RTO’s Nyquist limit, many RTOs can switch to a mode called random sampling. In this mode the scope collects as many samples as it can for each of many trigger events, each trigger contributing more and more samples and detail in a reconstructed waveform. Critical to alignment of these samples is a separate and precise measurement of time between each trigger and the next occurring sample clock. After a large number of trigger events the scope has enough samples to display the waveform with the desired time resolution. This is called the effective sampling resolution (the inverse of the effective sampling rate), which is many times higher than is possible in real-time mode. This technique relies on a random relationship between trigger events and the sampling clock, and can only be used for repetitive signals – those with relatively stable waveshape around the trigger event.

The sampler-extended real-time oscilloscope (SXRTO)

The maximum effective sampling rate of the PicoScope 9400 16 GHz models is 2.5 TS/s, with a timing resolution of 0.4 ps, which is 5000 times higher than the scope's actual sampling rate. With an analog bandwidth of up to 16 GHz, these SXRTOs would require a sampling rate exceeeding 32 GS/s to meet Nyquist's criterion and somewhat more than this (perhaps 80 GS/s) to reveal wave and pulse shapes. Using random sampling, the 16 GHz models give us 156 sample points in a single cycle at the scope's rated bandwidth or a generous 55 samples between 10% and 90% of its fastest transition time.

Bandwidth limit filters

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.

Frequency counter

A built-in fast and accurate frequency counter shows signal frequency (or period) at all times, regardless of measurement and timebase settings and with a resolution of 1 ppm.

Clock and data recovery

Clock and data recovery (CDR) is now available as a factory-fit optional trigger feature on all models.
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, at high speed this approach would accumulate timing skew and jitter between the clock and the data that could prevent accurate data decode. 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 and it can be used to decode and thus recover data accurately. We have also saved the cost of an entire clock signal path by now needing only the serial data signal.
