Intelligent differential inputs
With a traditional oscilloscope probe, single-ended measurements are made between a high-impedance input and a low-impedance ground.
With a differential oscilloscope, measurements are made between two high-impedance inputs, allowing measurements to be made across components and test points where neither side is grounded. Differential inputs also reject common-mode noise: noise picked up equally on both high-impedance inputs is rejected.
Each of the four input channels on the PicoScope 4444 features an intelligent probe interface that detects and identifies compatible probes, and powers them where necessary. Each channel can have its own choice of voltage or current probe.
Non-attenuating probes allow high-resolution, low-noise measurement of signals ranging from millivolts to ±50 V. Attenuating probes allow signals up to 1000 V CAT III to be measured. Current probes are available for currents up to 2000 A, also rated for 1000 V CAT III measurements.
PicoConnect 441: Measure from millivolts to ±50 V
The PicoConnect 441 differential voltage probes are suitable for voltages up to ±50 V (for higher voltages see the PicoConnect 442). The probes are fitted with industry-standard 4 mm connectors and supplied with detachable sprung hook probe tips. Other 4 mm accessories such as multimeter probes and crocodile clips are available separately.
As well as measuring non-grounded voltage signals, differential inputs are ideal for measuring current through sensing resistors. As neither side needs to be grounded, they can make high-side measurements. The sensitive input ranges, high resolution and fast sampling are ideal for measuring fast-changing currents in battery-powered and IoT devices.
The high-impedance, high-resolution inputs are also suited to biological and scientific research, as they allow measurements on low-level millivolt signals (2 mV/div at 12 bits) in the presence of common-mode noise without the need for expensive differential preamplifiers or differential oscilloscope probes. The probe is constructed with twinax cable (twisted-pair inner conductors with an outer shield) to ensure a high common-mode rejection ratio (CMRR). The outer screen of the cable can optionally be connected to a signal ground to improve rejection of common mode voltages and currents.
The PicoConnect 441 probes are also ideal for measuring differential signal sources such as CAN bus and balanced audio on a single channel and can be used to directly measure from bridge-type sensors such as load cells and pressure sensors.
PicoConnect 441 probes are ideal for work with low voltage SMPS, PicoConnect 442 (shown) for voltages up to 1000 V.
PicoConnect 442: 1000 V CAT III probes
The PicoConnect 442 is an attenuating differential voltage probe that increases the input range to 1000 V to allow the safe and cost-effective measurement of single-phase, three-phase and other signals, such as those found in motor drives and inverters.
The PicoConnect 442 probe requires no power supply or batteries. This makes it ideal for mains quality measurement and other long-term measurements.
The differential inputs of the PicoScope 4444 allow each channel to measure signals with different common-mode voltages. As an example, consider the battery pack in an electric vehicle. You can measure across the whole pack using one channel set to an input range of ±500 V, and at the same time set the other channels to ±5 V to measure across individual cells. This arrangement allows you to take advantage of the full resolution of the oscilloscope.
Three current probes with intelligent probe interface
Three different current probes are available with Pico D9 interfaces. TA300 and TA301 use the Hall effect to measure AC and DC currents without direct connection to the cable, and the TA368 uses the Rogowski principle for AC-only measurements. The intelligent probe interface powers the probes, so no batteries are required. It also means that when you connect either probe, the PicoScope software identifies it and configures the oscilloscope to read in amperes.
The TA300 current probe is a 40 A probe suitable for measuring signals from DC to 100 kHz. It is a precision probe for smaller currents and can resolve down to a few milliamps.
Powerful and portable
Just load the software, plug in the USB cable and you are up and running in minutes. Saving and printing are easy: PicoScope users can take copying waveforms into reports for granted.
On the bench, a PicoScope saves valuable space and can be placed right by the unit under test.
Laptop users benefit even more: with no power supply required you can now carry an oscilloscope with you all the time in your laptop bag. Perfect for the engineer on the move.
With our scopes, high-end features such as serial decoding, mask limit testing, advanced math channels and segmented memory are all included in the price.
To protect your investment, both the PC software and firmware inside the scope can be updated. Pico has a 26-year history of providing new features for free through software downloads. We deliver on our promises of future enhancements year after year.
Users of our products reward us by becoming lifelong customers and frequently recommending us to their colleagues.

PicoScope 4444 differential oscilloscope features
True differential measurements in high resolution
The PicoScope 4444’s four inputs allow you to make true differential measurements. The maximum input range at full scale is ±50 V (±1000 V CAT III using the PicoConnect 442 probe), and the maximum common-mode range is also ±50 V (also ±1000 V with the PicoConnect 442 probe). You can set the scope to measure at resolutions of 12 or 14 bits, far better than the 8-bit resolution typical of many oscilloscopes. The deep capture memory (up to 256 million samples shared by the active channels) is another advantage, allowing you to carry out long captures without lowering the sampling rate.
FFT spectrum analyser
The spectrum view plots amplitude against frequency, revealing details that would otherwise be hidden in an oscilloscope view. It is ideal for finding noise, crosstalk or distortion in signals. The spectrum analyzer in PicoScope is of the Fast Fourier Transform (FFT) type that, unlike a traditional swept spectrum analyzer, can display the spectrum of a single, non-repeating waveform. With up to a million points, PicoScope’s FFT has excellent frequency resolution and a low noise floor.
With a click of a button, you can display a spectrum plot of the active channels, with a maximum frequency up to the bandwidth of your scope. To focus on a specific frequency range, you can directly set the start and stop values of the analyzer frequency axis. A full range of settings gives you control over the number of spectrum bands (FFT bins), start/stop frequencies, scaling (including log/log) and display modes (instantaneous, average, or peak-hold). A selection of window functions allows you to optimize for selectivity, accuracy or dynamic range.
You can display multiple spectrum views alongside oscilloscope views of the same data. A comprehensive set of automatic frequency-domain measurements can be added to the display, including THD, THD+N, SNR, SINAD and IMD. You can even use the AWG and spectrum mode together to perform swept scalar network analysis.
The spectrum works with the waveform buffer so you can capture and rewind through thousands of spectrum plots or why not use the mask limit tests to scan through them all automatically? Spectrum masks can also work with PicoScope actions so you can leave the spectrum running continuously and choose to save mask fails to disk or even sound an alarm.
Deep-memory oscilloscopes
The PicoScope 4444 oscilloscope has a huge buffer memory of 256 million samples – many times larger than competing scopes of either PC-based or traditional benchtop design.
Deep memory produces several benefits: fast sampling at long timebases, timebase zoom, and memory segmentation to let you capture a sequence of events. Deep memory oscilloscopes are also ideal for serial decoding applications as they allow the capture of many thousands of frames of data.
Most other scopes with large buffers slow down when using deep memory, so you have to manually adjust the buffer size to suit each application. You don’t have to worry about this with PicoScope deep-memory scopes as hardware acceleration ensures you can always use deep memory while displaying at full speed.
DeepMeasure™
One waveform, millions of measurements.
Measurement of waveform pulses and cycles is key to verification of the performance of electrical and electronic devices.
DeepMeasure delivers automatic measurements of important waveform parameters, such as pulse width, rise time and voltage. Up to a million cycles can be displayed with each triggered acquisition. Results can be easily sorted, analyzed and correlated with the waveform display.
Digital triggering
The majority of digital oscilloscopes still use an analog triggering architecture based on comparators. This causes time and amplitude errors that cannot always be calibrated out and often limits the trigger sensitivity at high bandwidths.
In 1991 Pico pioneered the use of fully digital triggering using the actual digitized data. This technique reduces trigger errors and allows our oscilloscopes to trigger on the smallest signals, even at the full bandwidth. Trigger levels and hysteresis can be set with high precision and resolution.
The reduced rearm delay provided by digital triggering, together with segmented memory, allows the capture of events that happen in rapid sequence. On many of our products, rapid triggering can capture a new waveform every microsecond until the buffer is full.

Hardware acceleration ensures fast screen update rates even when collecting 10,000,000 samples per waveform
Hardware Acceleration Engine (HAL3)
Some oscilloscopes struggle when you enable deep memory; the screen update rate slows and controls become unresponsive. The PicoScope 4000A Series avoids this limitation with use of a dedicated hardware acceleration engine inside the oscilloscope. Its parallel design effectively creates the waveform image to be displayed on the PC screen. PicoScope oscilloscopes manage deep memory better than competing oscilloscopes, both PC-based and benchtop.
The PicoScope 4000A Series is fitted with third-generation hardware acceleration (HAL3). This speeds up areas of oscilloscope operation such as allowing waveform update rates in excess of 100 000 waveforms per second and the segmented memory/rapid trigger modes. The hardware acceleration engine ensures that any concerns about the USB connection or PC processor performance being a bottleneck are eliminated.

100 000 waveforms per second
An important specification to understand when evaluating oscilloscope performance is the waveform update rate, which is expressed as waveforms per second. While the sample rate indicates how frequently the oscilloscope samples the input signal within one waveform, or cycle, the waveform capture rate refers to how quickly an oscilloscope acquires waveforms.
Oscilloscopes with high waveform capture rates provide better visual insight into signal behavior and dramatically increase the probability that the oscilloscope will quickly capture transient anomalies such as jitter, runt pulses and glitches – that you may not even know exist.
The PicoScope 4444 oscilloscope uses hardware acceleration to achieve up to 100 000 waveforms per second.
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. Years of oscilloscope design experience can be seen in improved bandwidth flatness and low distortion.
We are proud of the dynamic performance of our products and publish our specifications in detail. The result is simple: when you probe a circuit, you can trust in the waveform you see on the screen.
