DAQ Software Freeware - Data Recorder Freeware

Free Measurement Data Acquisition Software - Measurement Data Recorder Software

The RogaREC software was developed for a wide variety of test and measurement devices, enabling the use of a front-end system such as a PC-based data recorder; RogaREC also works with any PC sound card.
 
RogaREC’s key feature is its ability to simulate a data recorder, eliminating the need for a user manual.
 
RogaREC supports the analog input channels of various sound cards, including Plug.n.DAQ, RogaDAQ2, RogaDAQ 384, RogaDAQ 4 and RogaDAQ16.

Measurement bandwidth is specified in Hz or kHz, depending on the device.

The display allows for switching between bar graph and oscilloscope views.

Overload indicators for each channel, pre- and post-triggering, and a recording duration function round out the RogaREC product.

Channel data is saved in the TEAC TAFFmat file format, which is compatible with post-processing analysis programs such as NVH Analyzer, FlexPro, DaDisp and more.

USB Audio Interface Free Software

Visual Analyser is a comprehensive, professional real-time software suite that transforms your PC into a complete set of measuring instruments.

It requires no additional hardware (as it utilizes the PC’s sound card), yet it also supports the use of specialized external hardware (examples of which can be found in the following section). Visual Analyser runs on the Windows operating system; the “Visual Analyser 26 Silvia” edition is currently available (supporting both 64-bit and 32-bit versions).

Thanks to the “Wine” utility, VA can also be run on Linux. Features for managing WAV, MP3, and FLAC files were introduced in the 2012 version and further refined in the 25 series. VA is freeware.

In this presentation, I will show you how to measure hum and infrasound using a calibrated USB measurement microphone.
 
Data analysis is performed using the open-source software SCILab.
 
The script, user manual, and report template are provided free of charge by engineer Edwin Krasser.
The first class 1 WS2F-compliant infrasonic measurement microphone with USB interface on the market.
 
It is equipped with a pre-polarized 1/2” microphone capsule that has been specially developed for low-frequency applications and works in a linear range from 1 Hz to 20 kHz.
 
The iSV1611 USB microphone preamplifier is able to perform measurements in two different level ranges simultaneously.
 
The measurement of infrasound is possible with very low ambient noise from a level of 15 dBA.
 
The USB microphone preamplifier is designed for three different sampling rates: 48 kHz, 96 kHz and 192 kHz.
 
This allows the iSV1611 digital preamplifier to be combined with other microphone capsules, e.g. for ultrasound or high-level measurements.
