PicoScope 4824 8 kanaals Scope |
 De
PicoScope 4000 serie is ontworpen om aan de verwachtingen
van de hedendaagse professionele ingenieurs.
Met zijn
8 channels en 12-bit resolutie met een ADC per kanaal,
voorziet de PicoScope 4824 de functionaliteit die u nodig
heeft voor preciezie, time-correlated waveform metingen op
meerdere kanalen eb eeb grote rnage van signaal types.
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 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.
Data Acquisition
With
256 Msamples of buffer memory the scope can capture over 5
minutes of continuous 50/60 Hz waveform data with high
timing resolution. Using the Software Development Kit (SDK)
you can write custom applications with storage limited only
by the PC hard disk size
Typical
Applications
•Single- and 3-phase
power transmission analysis
•Complex embedded
system development
•Multi-sensor systems
•DC
power supply sequencing
•Drives and controls
•Automotive system design, debug and validation
•7.1 and 5.1 audio system measurements |
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 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.
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.
