Adapter NVX2CAP‑24 is a passive adapter (switch) for connecting EEG electrodes with a TouchProof 1.5 mm (DIN 42 802‑ST) connector to EEG amplifiers.
Adapter NVX2CAP‑24 can be used in cases when it is necessary to quickly disconnect or connect patient-mounted electrodes to an EEG amplifier, for example, when registering a somnogram, or when it is necessary to increase the distance from the patient to the amplifier.
Marking of leads on the adapter corresponds to the system 10‑10.
Increasing the distance from the electrodes to the amplifier generally increases the level of interference from external sources (pickup) on the signal.
1.8 m connecting cables used in NVX2CAP have their own inter-wire capacitance up to 200 pF. For example, with an interelectrode resistance of 10 kΩ, the signal will additionally be attenuated by no more than 0.2% at a frequency of 150 Hz, but at a frequency of 80 kHz the attenuation will be already 30%.
