Gating (Acquisition) Settings Gated Check Box Lets the user enable the gating acquisition mode. Checking it will automatically check Stepped Check Box. That is, Gated Measurements are always carried out in Stepped Mode. Delay Edit Box Lets the user define the delay, in ms, applied between the signal generation and its acquisition. When different than 0, gating is active, even when gating or Stepped check boxes (but not both) are not checked. Typical gated use is quasi anechoic Frequency Response Analysis where it removes the time delay of the sound leaving the Speaker and reaching the Microphone. Alternative use, with gated not checked, might be removing the delay between the play and recording head in a three heads tape recorder as well as any digital processor that introduces delay in the signal path. When the settings are Not Stepped and Not Gated the delay value is reset automatically to 0; CLIO introduces a large delay anyway between start of generation and acquisition. The highest Delay value accepted is 320ms. Auto Delay Check Box & Auto Delay Frequency Edit Box If Auto delay is checked, when delay is used (see above) CLIO tries, using the Frequency entered in the Edit Box, to determine the delay automatically. The value found is displayed in the Delay Edit Box; reopening the Settings Dialog after the measurements has been taken allows to you to view the automatically chosen delay time. Impedance Settings Set how Impedance is calculated. When taking impedance measurements refer either to the internal impedance mode or to the ISense feature of the CLIOQC Amplifier & SwitchBox Model 2,3 and 4. If QC Box Select is selected the hardware setting of the QC Box determines directly the Impedance Mode (please refer to chap. 5.5.1) Distortion Settings An Edit Box allows you to type in the value, in dB, used by the graphical routines to raise the display of the distortion curves. Only the display of the curve is affected. The marker readings continue to display the real value which, if the rise value is different than 0, differs from the curve position. 134 Chapter 11 - Sinusoidal
11.2.4 SINUSOIDAL POST PROCESSING TOOLS The POST PROCESSING Dialog gives access to very powerful tools that, once defined, can be saved, reloaded and automatically be applied to every executed measurement. Loads a Sinusoidal process. Saves a Sinusoidal process. Adds a data value or compatible file to the current measurement. Subtracts a data value or compatible file to the current measurement. Multiplies the current measurement by a data value or compatible file. Divides the current measurement by a data value or compatible file. Shifts the current measurement by a dB value. Multiplies the current measurement by complex frequency. Divides the current measurement by complex frequency. Uses a reference measurement file taken at speaker terminals to calculate 1m sensitivity in dBSPL/W. The reference file should have dBV Y units while the one in memory should be in dBSPL. Temporally shifts the current measurement by a ms value. Affects phase response. Merges the current measurement with the part below the selected transition frequency of a selected compatible file. Combines the current measurement and the selected file to obtain a constant current impedance measurement. Both files should be in dBV. Combines the current measurement and the selected file to obtain a constant voltage impedance measurement. Both files should be in dBV. Chapter 11 - Sinusoidal 135
