The PicoScope 4444 with PicoConnect® probes: a new standard in differential measurement With four true differential inputs, 12- to 14-bit resolution and wide differential and common-mode voltage ranges, the PicoScope 4444 and its accessories offer accurate and detailed measurement for a multitude of applications. The 9-pin D-type connectors provide a true differential probe interface, and also allow the PicoScope 6 software to automatically identify the probe and select the appropriate display settings. With most oscilloscopes, just connecting to the signal of interest can be very...

Why make differential measurements? While you can make a wide variety of measurements with an ordinary ground-referenced scope, there are some circumstances where that just won’t work. VSIG VSIG Common-mode voltages are unwanted signals that are applied equally to both measurement terminals in your probing system. The circuit above consists of a signal source (purple) with AC and DC components producing a total output of VSIG, which we wish to measure. However, the circuit also contains an unwanted voltage source (green) that also has AC and DC components adding up to VCM, a common-mode...

Why use the PicoScope 4444 differential oscilloscope? There are, of course, plenty of differential probes available, all with similar inconveniences: bulky interface boxes, missing or flat batteries, snaking power leads... The PicoScope 4444 uses specially designed passive voltage probes that have smaller and lighter (or no) interface boxes. The PicoScope 4444 has high resolution and deep memory and lets you make multiple differential measurements at the same time, while never occupying more than one power socket. Its intelligent probe interface automatically configures the PicoScope...

Deep memory The PicoScope 4444 oscilloscope offers a large capture memory of 256 MS, allowing it to sustain high sampling rates across long timebases. Running at 12-bit resolution, it can sample at 400 MS/s all the way down to 50 ms/div giving a 500 ms total capture time. Powerful tools are included to allow you to manage and examine all of this data. As well as functions such as mask limit testing and color persistence mode, the PicoScope 6 software enables you to zoom into your waveform by several million times. The Zoom Overview window allows you to easily control the size and location...

Unique intelligent probe interface Signal integrity When you connect any Pico Technology probe with D9 connection to the PicoScope 4444, the PicoScope 6 software will detect, identify and, where necessary, power it. This means you spend less time setting up and don’t have to worry about battery packs or power supplies. The software automatically sets up the display and controls to match your probe. Careful front-end design and shielding reduces noise, crosstalk, and harmonic distortion. Years of oscilloscope design experience can be seen in improved bandwidth flatness, low distortion, and...

Oscilloscope kits We and our distributors supply three preconfigured kits with everything you need to get started with differential measurement. Each kit includes a PicoScope 4444 high-resolution differential oscilloscope and three differential voltage probes with Pico D9 connectors. The kits also come with a TA271 D9‑BNC adaptor, which lets you use traditional oscilloscope voltage probes and current probes, to make single-ended measurements with a ground-referenced probe. Finally, all three kits are delivered in a sturdy carry case, as shown below. These and a range of other accessories...

Accessories A number of accessories are available for the PicoScope 4444. These are available to purchase individually or in addition to a kit. Alternatively, you can design your own kit configuration on our website, www.picotech.com. Remember: all accessories marked with the symbol use Pico D9 connectors and our unique intelligent probe interface, so can only be used with the PicoScope 4444. Differential voltage probes PicoConnect 441 probe: measure from millivolts to ±50 V PicoConnect 442 probe: 1000 V CAT III test leads The PicoConnect 442 is a passive differential voltage measurement...

Current measurement probes (Pico D9) The TA300 and TA301 both use the Hall effect to measure AC and DC currents, while the TA368 uses the Rogowski coil principle to measure AC current without saturation. The intelligent probe interface means that the probes are powered directly by the PicoScope 4444, so you can use them to measure current for extended periods of time without worrying about flat batteries. It also means that when you connect any of these probes, the PicoScope 6 software automatically configures itself to display your signal. TA368 flexible current probe The TA300 current...

Flexible AC current probes (BNC) The TA326 and TA325 current probes use the Rogowski coil principle to measure AC currents up to 3000 A, without suffering from saturation. These probes have flexible sensor coils, enabling you to measure currents on conductors that clamp-type current probes just can’t get to, while the long battery life means you can leave them connected for longerterm measurements. Both of these probes are fitted with BNC connectors, so you will need to use TA271 single-ended D9-BNC adaptors to connect them to the PicoScope 4444. TA326 flexible current probe TA325 flexible...

PicoScope 6 software The PicoScope software display can be as basic or as detailed as you need. Begin with a single view of one channel, and then expand the display to include up to four live channels, plus math channels and reference waveforms. Display multiple scope and spectrum views in a configurable grid. Tools menu: Set up custom probes, serial decoding, reference waveforms, mask tests, alarms and macros from the Tools menu. Touchscreen controls: Handy buttons make fine adjustments easy on touchscreen devices. Flexible resolution: Choose between 12- and 14-bit resolution. Toolbars:...
