The (RTA) Real Time Analyzer function of the IE-35 is replete with colorful and easy-to-use (and find) features and subfunctions. The displayed spectrum is 20 Hz to 20 kHz and shows frequency bars while user has option to also show bars with peak indicators, average curve, preferred (or "target") curve, and bars as LEDs providing the familiar dB/LED readout. Maximum Resolution is as high as 1/24 octave above 125 Hz in Low Frequency Zoom mode.

Octave Display (1/1)- Shows ten octave bars



One Third Octave Display (1/3) - Shows thirty 1/3 octave bars



One Sixth Octave Display (1/6) - Shows sixty 1/6 octave bars in the same spectrum as the other displays. 1/6 octave resolution can be helpful in revealing narrower or finer frequency phenomena.



Max. Res. (as high as 1/24 Octave) - The Maximum Resolution display takes full advantage of the Axim screen resolution, resolving 2048 real data points to the 240 horizontal pixel resolution of the Axim screen. Regardless of the screen resolution shown on the Axim, the data are always captured (and stored) in Maximum Resolution.



LF Zoom - Low Frequency Zoom focusses the Maximum Resolution display from 20Hz to 2kHz at a 1 Hz resolution in order to help identify ring modes, feedback frequencies, standing waves and other LF phenomena.

(F)STC/NIC - Excellent feature for consultants. Quick and accurate transmission loss measurements in (F)STC, STC, (N)NIC, NIC. Take running or spot averages on both sides of a barrier, then at the touch of a button (in Subtract mode), display the plotted data and calculated Class number.

NC/NR - Quick and accurate Noise Criteria or Noise Reduction measurements.

Averaging - By activating Average, the user can automatically collect a continuing series of samples which are then averaged to a single line of data points. The user can also manually collect samples using Trigger mode. The Average data can be saved to a file name, ported to a PC and further manipulated or printed. The IE-35's method of averaging is easier and superior than attempting to average individual stored memories. The IE-35 performs two types of averaging: Arithmetic and Power Averaging.

Freq Detect - Frequency Detection can be activated in the Max. Res. mode and will allow the user to identify feedback frequencies, room ring modes, and other sinusoidal anomalies. The Frequency Detection function can be viewed in the Max. Res. real time curve, or the Max. Res. decay curve.

Preferred Curve - The Preferred Curve function allows the user to manually create (or load from a stored file) a preferred or "target" curve which presents itself as a screen overlay. Target curves can be used for equalizing to a specific "desired house curve" or where any specific, targeted end result is desired.

Memory Management - The IE-35 has a very flexible Memory Management screen that allows renaming, storing, loading, clearing and other memory management functions. Scratch memories, preferred curve memories, curve subtraction results, and peak value curves can be loaded, stored, cleared and renamed with Memory Management. Virtually unlimited storage memory.
