1.7 Connecting accessories to the PicoScope 4444
WARNING
To prevent electric shock or damage to the unit, only connect Pico Technology D9‑
type accessories directly to the oscilloscope. BNC‑type accessories should only be
used in conjunction with the TA271 or TA299 D9(m)‑BNC(f) adaptors. Use of any
alternative connectors is dangerous and will invalidate the warranty.
Visit www.picotech.com for more information about approved accessories and how to order
them.

1.8 Using the TA299 D9-dual BNC adaptor
The TA299 D9‑dual BNC adaptor allows you to make differential measurements using two
single‑ended probes with BNC connectors.
The PicoScope 4444 will identify the TA299 adaptor, but not the probes connected to it. Use
the Channel Options menu in the PicoScope 6 software to set up your probes, and compensate
them using the pins on the back of the scope unit.
1.8.1 Compensating a pair of probes for common-mode voltages
This example uses two TA375 probes set to 10:1 attenuation, but applies to any single‑
ended attenuating probes with BNC connectors: just remember to adjust the Probes settings
accordingly.
