Since 1991 we have been supplying the world with test and measurement equipment. At Pico we realize that your choice of test accessories can be almost as important as your choice of test equipment. Here you can purchase a variety of test and measurement accessories quickly and securely online.
The TA042 is an active differential probe suitable for high common-mode voltage measurement applications up to ±1400 V (DC + peak AC). It is capable of acquiring higher speed signals of up to 100 MHz.
This differential probe extends the functionality of standard single-ended input oscilloscopes to allow a safe and accurate method of making high-voltage differential measurements. Applications include making safe measurements in power circuit applications and acquisition of low speed balanced differential signals found in serial communications buses.
The TA042 is an active probe and therefore requires power to function. Four AA batteries are included as standard. Not included as standard but available as optional extras, the PS008 power supply and TA059 Probus power adapter are also available to purchase.
