New in version 4.00, a free-floating resizeable Sound Level Meter has six standard and unlimited custom weighting curves, plus five standard or custom adjustable attack and decay time responses. Continuous Peak buttons allow viewing either the current SPL, or the peak SPL since the last Peak Reset.

The Sound Level Meter joins the existing Voltmeter and Frequency Counter options, all loaded with advanced features and now including adjustable decimal places.

Labels and Fields areas have been added to hold any info you want associated with your data. Contents are saved with .DQA files, and shown on file open.

Pro-level users can now automate complex tasks with a scripted Macro system that includes loops, custom status and prompt messages, timers (including the ability to awaken the system from standby), event waits, local variables that persist between sessions, and bounded random value entry to controls. Macros can be invoked via user-defined hot-keys or selected from a list. Macro collections can be saved to and loaded from .MAC files, including an auto-loaded file that can run a custom start-up macro automatically. (Non-Pro users, including free expired-trial users, can use all these features but can't save macro files. They can use files created before the trials expired, and they can use macros created during the current session.)

Also for Pro users, the Juxt Array system allows multiple traces to be stored in memory and shown individually or as multi-trace displays, sorted and labeled according to a chosen Field, date, or time. Trace arrays can be saved and loaded as .JXT files.

Download Daqarta now and try it FREE for 30 sessions or 30 days.

You can purchase Daqarta for as little as US $29.00 (Personal/Hobby license) to keep using all Daqarta features except multi-trace memory arrays and macro file save, or $99.00 for a Professional license to use these as well. Note that these are permanent licenses that will work with all future versions of Daqarta... you only pay once.

But, even if you don't buy, Daqarta will keep on working with only the signal inputs disabled. Essentially, it reverts to a freeware signal generator (previously offered separately as DaqGen), plus all the advanced Daqarta features like:

Multi-channel display shows all active channels simultaneously, on the same axes.

Dual cursors and readouts allow direct reading of waveform or spectrum values, as well as their difference or the summation of the values (area) between them for true RMS calculation.

Expandable X and Y axes allow magnification of selected portions of waveforms or spectra.

Advanced Trigger options allow you to see what happened before or after the trigger event.

256-color Spectrograms show time, frequency, and amplitude in a "voiceprint" format. Full control over color palette and dynamic range.

Data file operations allow you to save signals for later analysis, as single-screen or arbitrary length (DDisk) files. Even after the trial period, this allows you to to create your own Arb or Play Wave files for the Generator, for example.

You can open saved files, including standard WAV files collected elsewhere, to analyze waveform, spectrum, or spectrogram displays of file data. Even many "unsupported" formats can be opened via manual selection of format parameters.

Calibration values remain in effect even after the trial period.

Extensive Help includes tutorials on Fourier Transforms, synchronous waveform averaging, applications, and much more.
