Navcon Software Products
Navcon is marketing special purpose software used by our consulting engineers. The software runs under Agilent Instrument Basic or MATLAB.

AIMAP

Acoustic Intensity Mapping is a MATLAB based stand alone program for the 3 dimensional surface contour mapping of acoustic intensity and sound pressure data. Operating on Hewlett Packard SDF data, the program also calculates component sound power levels and features many graphical displays and calculation tools. [more Information]

OCT_ASC

Octave ASCII is a Agilent Technologies Instrument Basic program which runs within the 35670A and 35665A analyzers. OCT_ASC allows the test engineer to collect large amounts of SDF data and store it to a single ASCII file which can be opened in a spreadsheet, word processor, MATLAB, etc. NRRO: Non-repetitive Run-out is a MATLAB based stand alone program for the identification of non-repetitive run-out in disk drive spindle motors. The program operates on Hewlett Packard SDF data computing / identifying NRRO frequencies and the statistical information associated with a typical lot testing. SRS: Shock Response Spectra is a MATLAB based stand alone program for the calculation of shock response spectra from measured time histories using a time integration algorithm. The program reads SDF, ASCII and matfile formatted data, allows 1/3 octave, 1/6 octave and 1/12 octave calculations with user defined damping, and hosts many graphical displays and calculation tools.

Tonal

ISO7779 Tonal is a Agilent Technologies Instrument Basic program which runs within the 35670A and 35665A analyzers. Tonal allows the test engineer to identify discrete prominent tones in accordance with Annex D of ISO 7779, "Measurement of impulsive sound pressure levels and discrete tones at the operator position". The results of the tonal evaluation can be sent directly to a laser printer or stored to disk in an ASCII file. The disk files can be opened in a spreadsheet, word processor, MATLAB, etc. HCAL (Hand-Help Calibration) is a Agilent Technologies Instrument Basic program. HCAL customizes the 35670A for the purpose of performing hand-held calibration of accelerometers. [more Information]

RCAL

Ratio Calibration (RCAL) is a Agilent Technologies Instrument Basic program. RCAL customizes the 35670A for the purpose of performing ratio calibration for impact testing. The frequency response of an inertial mass is measured by mounting an accelerometer on one side of it and impacting on the other side. The calibration FRF can be used as a calibration curve or a single, averaged value can be determined for a given frequency range as a calibration value. [more Information]

DCAL

Drop Calibration (DCAL) is a Agilent Technologies Instrument Basic program. DCAL customizes the 35670A for the purpose of performing drop calibration of accelerometers and force sensors. DCAL based on a predictable and repeatable motion, that a body in free-fall experiences under a constant gravitational acceleration. [more Information]

CHANREF

Channel Reference (CHANREF) program just puts point number and directions into the header of the SDF files. [more Information] RRIT (Roving Response Impact Testing) is a Agilent Technologies Instrument Basic program.

RRIT

RRIT is a modal data acquisition method in which frequency response functions are measured between a fixed impactor and one or more roving response transducers. The basic procedure is that the test system is repeatedly impacted at an input position while the response transducers are roved about the measurement positions. RRIT is a single reference technique, but to collect multiple reference data with RRIT, the procedure is repeated for other input positions. Alternatively, the impacts could be made at all input positions before relocating the response transducers. [more Information]

MRIT

Multiple Reference Impact Testing (MRIT) is a Agilent Technologies Instrument Basic program. MRIT does not imply impacting a test structure with more than one hammer. Instead, the outputs are taken as the references, rather than the input. MRIT is a modal data acquisition method in which frequency response functions (FRF) are measured between a single, roving impactor and multiple, fixed response transducers. Possible reference transducers are accelerometers, microphones, and proximity probes. A set of multiple reference FRFs is generated by applying the reciprocity relationships to determine the response at the impact locations. The set of measurements can then be treated as multiple input data and processed with multiple reference modal parameter estimation software. [more Information]
