Adapter NVX2CAP 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 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.
Attention!
-
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%.
