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 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.
