PicoScope 2405A

The PicoScope 2405A from Pico Technology is a 4-channel USB oscilloscope that offers 25 MHz bandwidth and 500 MS/s real-time sampling in an ultra-compact, USB-powered form factor. With four independent analog inputs, a built-in function generator and arbitrary waveform generator, a spectrum analyzer and 38+ serial protocol decoders included as standard, it gives embedded and electronics engineers a genuine alternative to a benchtop scope, one that fits in a laptop bag and runs from a single USB cable.

A 4-channel USB oscilloscope: 25 MHz bandwidth, 500 MS/s

The 2405A is the entry point to four-channel measurement in the PicoScope 2000 Series. Four full analog inputs on BNC connectors let you watch a power rail, a clock, a data line and a control output at the same time, the kind of mixed-signal visibility a two-channel scope cannot give you. Maximum real-time sampling is 500 MS/s on a single channel, 250 MS/s on two channels and 125 MS/s with three or four channels active, and equivalent-time sampling (ETS) pushes the effective rate to 5 GS/s on repetitive signals. The 48 kS capture memory is shared between the active channels, and enhanced resolution mode lifts the effective vertical resolution from 8-bit up to 12-bit for low-frequency measurements.

PC-based oscilloscope: the benchtop alternative

A PC-based oscilloscope moves the front panel, display and processing onto your computer. That has two practical benefits on the 2405A. First, the screen: PicoScope 7 dedicates almost the entire monitor to the waveform, so you read four channels, serial decode tables and a spectrum view at the high resolution of a laptop display rather than a small benchtop screen. Second, the toolset travels with the software, automatic measurements, deep zoom, persistence display, math channels, mask limit testing and DeepMeasure are all included and improve with every free PicoScope 7 update, without paying to enable hardware options. The Pico-pioneered fully digital triggering architecture gives 1 LSB trigger accuracy up to full bandwidth, so the scope triggers cleanly even on small signals.

A portable oscilloscope with a built-in AWG and spectrum analyzer

At 130 × 104 × 18.8 mm and under 0.2 kg, the 2405A is a true portable oscilloscope: it fits in a laptop bag alongside its probes and runs from the USB bus, with no external power brick to carry. Despite the size, the instrument is fully featured. A built-in function generator and arbitrary waveform generator output sine, square, triangle, ramp, sinc, Gaussian, half-sine and custom waveforms from 0.03 Hz to 1 MHz on a front-panel BNC, useful for stimulating amplifiers and filters and, combined with the FFT spectrum analyzer, for swept scalar network analysis. The spectrum view plots amplitude against frequency from DC to the scope’s bandwidth, with frequency-domain measurements including THD, THD+N, SNR, SINAD and SFDR for finding noise, crosstalk and distortion.

Where the PicoScope 2405A fits in the 2000 Series

The 2405A is the 4-channel, 25 MHz model in the PicoScope 2000 Series. The higher-bandwidth 4-channel “B” models, the 2406B, 2407B and 2408B, step up to 50, 70 and 100 MHz respectively with 1 GS/s sampling and deeper capture memory. Engineers who need four analog channels but work primarily with signals below 25 MHz, power-supply design, sensor signal conditioning, motor and embedded control, or low-speed serial buses, get the channel count they need without paying for bandwidth they will not use. GSAS Micro Systems helps you confirm whether the 2405A’s bandwidth and memory suit your highest-frequency signal, or whether a “B” model is the better fit.

Applications

The PicoScope 2405A’s four channels, built-in AWG and serial decoding suit a wide range of design, test and service work:

• Embedded and mixed-signal debugging: probe power rails, clocks, data and control lines on four channels at once, with serial decode for I2C, SPI, UART, CAN and LIN.
• Power-supply and sensor work: capture rails, ripple and conditioned sensor outputs below 25 MHz, with enhanced resolution for low-frequency detail.
• Automotive and industrial bus analysis: CAN, CAN FD, LIN, FlexRay and SENT decoders are included as standard for vehicle and field-bus diagnostics.
• Education and lab benches: a single compact instrument provides scope, spectrum analyzer and signal generator for teaching and student projects.
• Field service and repair: a USB-powered, laptop-bag-sized instrument for fault-finding and on-site test where a benchtop scope is impractical.
