Combining high resolution technology, with 256 Msamples buffer memory, powerful debug tools and a built-in arbitrary waveform generator, the PicoScope 4824 is the ideal oscilloscope for precise measurements and rapid debug. Tools such as Mask Limit Testing, Serial Bus Decoding, Advanced Digital Triggers, and Persistence Mode help to track problems for rapid troubleshooting. Waveforms are captured in high resolution, making it easy to distinguish signal from noise to ease debug and analysis.
8 channel oscilloscope
The PicoScope 4824 is a low cost, portable solution for multi-input applications.
With 8 high-resolution analog channels you can easily analyze audio, ultrasound, vibration, power, and timing of complex systems, and perform a wide range of precision measurement tasks on multiple inputs at the same time. Although the scope has the same small footprint as Pico’s existing 2-and 4-channel models, the BNC connectors still accept all common probes and accessories with ample spacing of 22 mm.
Despite its compact size, there is no compromise on performance. With a high 12-bit vertical resolution, bandwidth of 20 MHz, 256 MS buffer memory, and a fast sampling rate of 80 MS/s, the PicoScope 4824 has the power and functionality to deliver accurate results. It also features deep memory to analyze multiple serial buses such as UART, I2C, SPI, CAN and LIN
plus control and driver signals.
Applications - Power measurements
The PicoScope 4824 is ideal for making a range of power measurements on high voltages and currents and low-voltage control signals. For the best results, use a Pico differential voltage probe (TA041
) in combination with a current clamp (TA167
). To improve the efficiency and reliability of power designs, the scope can display and analyze standby power dissipation, inrush current, and steady-state power consumption. PicoScope’s built-in measurements and statistics of parameters such as true RMS, frequency, peak-to-peak voltage and THD allow accurate analysis of power quality.
Nonlinear loads and modern power-conversion equipment produce complex waveforms with significant harmonic content. These harmonics reduce efficiency by causing increased heating in equipment and conductors, misfiring in variable speed drives, and torque pulsations in motors. The 12-bit PicoScope 4824 has the precision to measure distortion typically up to the 100th harmonic. On the supply side, power quality issues such as sags and dips, swells and spikes, flicker, interruptions and long-term voltage and frequency variations can also be checked for regulatory compliance.
In a 3-phase distribution system, it is important to characterize and balance loads across phases. With 8 channels the PicoScope 4824 can monitor waveforms of current and voltage on all 4 conductors of a 3-phase plus-neutral system. This helps to identify mismatches that can cause breaker tripping, or transformer and conductor overheating.
Applications - Complex embedded systems
When debugging an embedded system with a scope, you can quickly run out of channels. You may need to look at an I2C or SPI bus at the same time as multiple power rails, DAC outputs and logic signals. With eight channels, the PicoScope 4824 can cope with all of this. Choose whether to decode up to eight serial buses, with analog waveforms and decoded data both visible, or a combination of serial buses and other analog or digital signals. PicoScope provides advanced triggering on all channels, so you can search for runt pulses, drop-outs and noise as well as looking for data patterns using the 4-input Boolean logic trigger.
High signal integrity
Most oscilloscopes are built down to a price. PicoScopes are built up to a specification.
Careful front-end design and shielding reduces noise, crosstalk and harmonic distortion, meaning we are proud to publish the specifications for our scopes in detail. Decades of oscilloscope design experience can be seen in both improved pulse response and bandwidth flatness, and low distortion. The scope features 12 input ranges from ±10 mV to ±50 V full scale, a huge dynamic range, and 60 dB SFDR. The result is simple: when you probe a circuit, you can trust in the waveform you see on the screen.
Most digital oscilloscopes still use an analog trigger architecture based on comparators. This can cause time and amplitude errors that cannot always be calibrated out. The use of comparators often limits the trigger sensitivity at high bandwidths and can also create a long trigger re-arm delay.
For over 20 years Pico have been pioneering the use of full digital triggering using the actual digitized data. This reduces trigger errors and allows our oscilloscopes to trigger on the smallest signals, even at the full bandwidth. All triggering is digital, resulting in high threshold resolution with programmable hysteresis and optimal waveform stability.
The reduced re-arm delay provided by digital triggering, together with segmented memory, allows the capture of events that happen in rapid sequence. At the fastest timebase, rapid triggering can capture a new waveform every 3 microseconds until the buffer is full. The mask limit testing function helps to detect waveforms that fail to meet your specifications.
As well as the standard range of triggers found on most oscilloscopes, the PicoScope 4824 has a comprehensive set of advanced triggers built in to help you capture the data you need.
These include pulse width, windowed, and dropout triggers to help you find and capture your signal quickly.

On some oscilloscopes, enabling deep memory has a penalty: the screen update rate slows down and the controls become unresponsive as the processor struggles to cope with the amount of data. Thanks to the hardware acceleration inside PicoScope deep-memory oscilloscopes, you can collect waveforms containing hundreds of millions of samples while keeping fast screen update rates and a responsive user interface.
Dedicated hardware inside the oscilloscope processes multiple streams of data in parallel to construct the waveform that will be displayed on the screen. This is done far faster than any PC processor could manage, and together with USB 3.0 SuperSpeed data transfer eliminates any bottlenecks between the oscilloscope and the PC.
For example, the scope may be set to capture 100,000,000 samples but the PicoScope display window may be only 1000 pixels wide. In this case, the scope intelligently compresses the data into 1000 blocks of 100 000 samples each. Unlike simple decimation, which throws away most of the data, PicoScope hardware acceleration guarantees that you see any high-frequency details such as narrow glitches, even when the display is zoomed out.
Store up to 10,000 waveforms in the buffer
Ever spotted a glitch on a waveform, but by the time you’ve stopped the scope it has gone? With PicoScope you no longer need to worry about missing glitches or other transient events. Depending on the settings, PicoScope can store up to the last ten thousand waveforms in its buffer.

Arbitrary waveform and function generators
In addition, the PicoScope 4824 has a built-in low-distortion, 80 MS/s, 14 bit arbitrary waveform generator (AWG), which can be used to emulate missing sensor signals during product development, or to stress test a design over the full intended operating range. Waveforms can be imported from data files or created and modified using the graphical AWG editor included.
A function generator is also included, with sine, square, and triangle waves up to 1 MHz, along with DC level, white noise, and many more standard waveforms. As well as level, offset and frequency controls, advanced options allow you to sweep over a range of frequencies. Combined with the spectrum peak hold option, this creates a powerful tool for testing amplifier and filter responses.

With the click of a button, you can open a new window to display a spectrum plot of selected channels up to the full bandwidth of the oscilloscope. A comprehensive range of settings gives you control over the number of spectrum bands, window types and display modes.
A comprehensive set of automatic frequency-domain measurements can be added to the display, including THD, THD+N, SINAD, SNR and IMD. You can even use the AWG and spectrum mode together to perform swept scalar network analysis.

The SuperSpeed USB 3.0 connection not only allows high-speed data acquisition and transfer, but also makes printing, copying, saving, and emailing your data from the field quick and easy. USB powering removes the need to carry around a bulky external power supply, making the kit even more portable for the engineer on the move.
The PicoScope 4824 is also backward compatible with older USB2.0 devices.
