Trident Developer's Module
Trident mX Developer Module (TDmX)TDmX is a source code version of Nelson Acoustics’ Trident multi-channel real-time analyzer. It provides users with the capability of integrating Trident functionality into larger and/or more lab-specific LabVIEW™ projects. Typical projects might include a lab-specific test procedure, automated test control, or appending test results into a database.
Trident multi-channel functions include:
? 1/3 octave band analysis from 20 Hz to 20 kHz, A-weighted and Linear
values
? narrowband power spectrum, power spectral density, or magnitude
? ISO 532B (Zwicker) Loudness in sones, phons and specific loudness.TDmX ships as a group of libraries and VIs. Several of the VIs are password-protected in order to prevent unintentional damage and to protect intellectual property. Many of the lower-level library SubVIs are not password protected: modification of these is strongly discouraged.
Coding with TDmX requires some knowledge of acoustic multi-channel analyzer use and functionality. Instrument settings can have a strong influence on measured results. The user assumes the responsibility of making settings appropriate to the measurement task at hand.
NI DAQmX relies on the host processor to perform signal processing. Thus the number of channels that can be successfully measured is influenced by the sampling rate, processor speed, graphics load, buffer size, and the degree to which analyzed results must be displayed in real time.
