The revised terminal names used in this document are usually similar to the names they replace. For a complete list of Traditional NI-DAQ terminal names and their NI-DAQmx equivalents, refer to the Terminal Name Equivalents table in the S Series 1.

4 Averaged numbers assume averaging of 100 single-channel readings. Measurement accuracies are listed for operational temperatures within 1 C of internal calibration temperature and 10 C of external or factory-calibration temperature. NI recommends a one-year calibration interval. The Absolute Accuracy at Full Scale calculations were performed for a maximum range input after one year and 100 points of averaged data. 1,000 h national instruments Corporation5NI 6143 SpecificationsTypical Performance GraphsGrounded-Input Histogram10 kHz, dB, 64 k point FFTG rounded-input 64 k point FFTTHDC ommon-mode RejectionBandwidth0500100015002000250030 0035004000 3 2 10123 HitsCode0 20 40 60 80 100 120 140020000400006000080000100000 120000 Frequency (Hz)Magnitude (dB) 20 40 60 80 100 120 140020000400006000080000100000 120000 Frequency (Hz)Magnitude (dB)010510095908580757010010001000010000 0 Frequency (Hz)THD ( dBc)CMRR (dB)304050607080901010010001000010000010 00000 Frequency (Hz) 10 8 6 4 2021000100001000001000000 Frequency (Hz)Magnitude (dB)NI 6143 I/ONumber of channels.
