8 channel oscilloscope
The Pico Technology PicoScope 4824 USB Oscilloscope is a low cost, portable solution for multi-input applications.
With 8 high-resolution analog channels it 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 20 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 USB Oscilloscope is ideal for making a range of power measurements high voltages and currents and low-voltage control signals. For the best results, use a Pico differential voltage probe (TA041 or TA057) 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.
With 256M samples of buffer memory the PicoScope can capture over 5 minutes of continuous 50/60 Hz waveform data with high timing resolution. Using the Software Development Kit (SDK) custom applications can be written with storage limited only by the PC hard disk size.
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 Pico Technology PicoScope 4824 USB Oscilloscope 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
In debugging an embedded system, the application under test may quickly use up all channels available on a scope. The application may call for looking at an I2C or SPI bus at the same time as multiple power rails, DAC outputs and logic signals. With eight channels, the Pico Technology PicoScope 4824 USB Oscilloscope 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.
