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.
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.
Human heartbeat captured on PicoScope 4444
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.
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 differential 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.
TA300 and TA301 current probes
Two different current probes are available with Pico D9 interfaces. Both use the Hall effect to measure AC and DC currents without direct connection to the cable. The intelligent probe interface powers the probes, so no batteries are required. It also means that when you connect either probe, 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.
In addition to the TA300 and TA301, Pico stocks a wide range of AC and DC current clamps with BNC connectors that can be connected to the PicoScope 4444 using the TA271 D9 to BNC adaptor.
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.
