Revision History - v6.00
Daqarta v6.00.1 - 4 January 2011
Daqarta v6.00 - 1 January 2011
Certain Macro commands now accept string expressions that contain multiple items, including variables. Allowed with any command that specifies a file name, plus Notes, Labels, Fields, and LogTxt. Notes and LogTxt also accept formatting commands.
New LogTxt macro allows creation of custom reports or continuous data logging. Can use string variables to record values that don't otherwise appear on a Daqarta trace, such as Freq to read the Frequency Counter, Volts for the Voltmeter, or SPL for the Sound Level Meter. Can be invoked via Remote Control.
New A: command line parameter allows arbitrary auto-run macro ID instead of default '!'. Allows starting Daqarta for different test setups from separate desktop icons, or via batch file command.
New Sample Rate Select dialog supports sample rates up to 192000 Hz, manual Sample Rate Adjust now allows up to 262144 Hz. Generator frequencies (modulator frequencies as well as main Tone Frequencies) can now be set as high as 131072 Hz.
New Slow controls in X-Axis Dialog support slow input sample rates (down to one sample per day or slower) via Decimation, while maintaining full output sample rates for high-frequency stimulus generation. Allows slow scroll rates for chart recorder display of DC signals like temperature and pressure.
Low-Frequency Response Via Decimation topic added to Help.
Envelope mode shows maximum and minimum waveform value during each effective Decimate sample period.
Demodulate and Signed Decimate modes allow standard sound cards to record DC signals using External DC-to-AC Modulator circuit under new DC Measurement topic. Sound Card DC Input Modification allows DC inputs with full high frequency response.
Zero dialog now has independent Screen Zero and Data Zero controls, including Average, Peak, and new Manual mode with individual channel settings to support DC measurement systems. Histogram and PSTH averages apply Manual Zero if active.
Bug Fix: Macro IF statement could give reversed logic result.
Bug Fix: Voltmeter showed garbage in Exponential, Histogram, and PSTH wave average modes.
Bug Fix: Possible bad X-axis labels with eXpand active using negative Trigger Delay.
Bug Fix: PSTH Threshold value did not match actual threshold used to compute PSTH.
Bug Fix: At very low sample rates in Pitch Track mode, a negative octave number was shown as a large positive octave. Negative MIDI numbers were shown as '00' instead of proper value in red. Also, pitch trace near top of display could vanish.
Bug Fix: Pitch Hysteresis setting could be incorrect under some conditions.
