The two key accessories are the new PicoConnect differential voltage probes. We have used 9-pin D-type connectors to create a true differential probe interface. These Pico D9 connectors also allow the PicoScope software to automatically identify the probe and select the appropriate display settings. The TA271 and TA299 adaptors allow you to use the PicoScope 4444 with traditional BNC-connected accessories. 1:1 differential probes 1000 V CAT III differential probes With most oscilloscopes, just connecting to the signal of interest can be very frustrating when one Testing and characterization of power supplies can present the oscilloscope user with many of the connection points has to be grounded. With the PicoConnect 441 1:1 differential voltage challenges, such as hazardous voltages (often floating without reference to ground), feedback probe, the PicoScope 4444 high-resolution differential oscilloscope allows the freedom to connect circuitry with electrical isolation, and a wide range of signal levels. One wrong connection of a to and visualize signals that are off-limits to a grounded-input oscilloscope. Connect directly to ground lead and sparks can fly Using the PicoConnect 442 1000 V CAT III differential voltage current-sensing resistors and differential signals, or across non-grounded components in a signal probe with the PicoScope 4444, you can easily connect to and visualize the wide range of signals path. that need to be characterized. The PicoConnect 441 probe does not attenuate your signal and is well suited to numerous The PicoConnect 442 probe has a 25:1 attenuation ratio and is suitable for testing in a range of electronics applications, as well as biomedical and other scientific research, as it allows high-speed applications, including distribution boards, circuit breakers, junction boxes, switches, fixed socket high-resolution measurements on signals between 10 mV and 50 V in the presence of common- outlets and industrial equipment such as permanently connected stationary motors. mode voltages and noise.
