The TA300 is a 100 kHz bandwidth, single-range 40 A AC or DC current probe using the D9 connector specific to the PicoScope 4444 differential oscilloscope. On connection with the scope, the probe is instantly sensed and the vertical range automatically set up in PicoScope software. The probe is also powered by the scope through the D9 connector.

Note: When using the PicoScope 4444 with USB power (no AC adaptor connected), sensor power is limited to a maximum of 3 x TA300 probes at once.
