Click on the “Analyzer Settings” to open the advanced RTA setting dialogue box. Here you can configure different analyzer settings.
The following modifications can be made in the Analyzer setting window using the channels list:
- Source: This defines the input of a certain analyzer channel. By clicking on the control a context menu pops up from which the desired source can be chosen.
If there is no input available, “None” will be shown as the source by default.
- Name: Enter the name of an analyzer channel. This name appears in the channel viewer and will be set as a default name when storing measurements as traces.
- Calib[db]: When a channel is being calibrated for a certain microphone the determined value appears here. It can also be overwritten by entering a desired value. The unit is “dBFS”; the analyzer input stream will be scaled by this value. Based on the microphone calibration unit, this unit will be set. The same unit will be suffixed to the Y-Axis unit for the Spectrum mode graph. Examples: dBFS(RMS), dBSPL(RMS) etc.
- AvgCH: When the analyzer is in “Multiplexer” mode this control determines to which “Average” channel the analyzer source is added. When the channel is “0,” it is not included; when it is “1” or “2,” it is added to “Average-1” or “Average-2,” respectively.
Channels 17 and 18 are reserved for the “Average” channels. Here only the name can be edited.
- Delay: Add or subtract time delay in milliseconds. In Phase measurement, we can add/subtract time delay to compensate for HW and/or acoustic delay.
- Peak Trace: Peak hold trace allows the analyzer to display a secondary live trace for each channel showing the highest amplitude values for each frequency. This feature helps to mark the highest amplitude reached at each frequency.
By default, all the peak traces will be disabled. This can be enabled using the checkbox available in the analyzer settings tab for each channel.
Click “Delete” in the data context menu of the peak trace in the trace list to reset the peak trace. When a peak trace is deleted, the database will also delete the current peak trace and create a new one.
You should be able to select a time constant for peak trace. Depending on the time constant setting, the peak hold trace shall show the maximum value that occurred within the defined moving time window.
Peak Hold settings include:
- Slow
- Fast
- Forever
