A calibrated, instrumentation-grade (TYPE I or TYPE II), audio analysis system built upon an open PocketPC platform. Offering detailed Real Time Analyzer (RTA) and Sound Pressure Level (SPL) functionality including accurate and easy-to-use RTA, SPL Monitor, Strip Chart Recorder, Polarity Checker, Oscilloscope, Signal Generator, Audio Level Volt Meter, and more. All combined into an extremely convenient, brilliantly colored, and useful PDA package.

Virtually unlimited data storage and fully capable of downloading data to PC for archiving and graphic reporting using free IvieXLS (Microsoft Excel Template) software (included with any IE-33 purchase).

Internal battery life capable of running about 2 hours in full energy burn mode. Standard HP/Compaq accessory battery (highly recommended Ivie part #EP-1840) adds another two hours in full energy burn mode.

Inputs: Mic/Channel 1, Channel 2
Outputs: 3.5mm stereo jack

Comes with iPAQ (standard model 5550 or 5555), custom jacket IE-33 software, IvieXLS PC software, belt pouch, and TYPE II microphone.

RTA (FFT-based):

-- Max resolution of 2048 data points (diplayed at 240 freq. data points... much greater than 1/2 octave.)
-- Selectable weighting filters: Flat, A, and C weighting... and octave filters at 125Hz, 250 Hz, 500Hz 1 kHz, 2 kHz, and 4 kHz
-- Detectors: fast, slow, peak, impulse
-- Three display integration times (adjustable display decay 1, 2 and 3)
-- Peak detect and hold
-- Frequency detection display
-- Low freq. zoom (20Hz to 2kHz at 1Hz resolution)
-- Powerful averaging (continuous or trigger mode)
-- NC/NR
-- (F)STC, STC, (N)NIC, NIC
-- Easy subtraction
-- Multiple scratch pad memories
-- Unlimited storage capability

SPL Monitor:
-- 4 Digit readout with 0.1dB resolution
-- Large digital display with two user adjustable SPL threshold warnings
-- Bar graph display
-- Response modes: fast, slow, peak, impulse
-- Selectable weighting filters: Flat, A, and C weighting... and octave filters at 125Hz, 250 Hz, 500Hz 1 kHz, 2 kHz, and 4 kHz
-- Meets ANSI S1.4-1983 Type II with standard Ivie mic; Type I with optional Ivie mic (1134) and preamp (IE-2P)

Seat-to-Seat:
Measure Seat-to-Seat SPL variation in all pass, several octave bands, with and without weighting. Easy to read graphic display with digital and bar graph readout.

Strip Chart:
-- Unique strip chart display shows amplitude over time
-- User settable time scale from continuous to up to 8 hours
-- Acoustic Time Study Graph
-- Detectors: fast, slow, peak, impulse
-- Selectable weighting filters: Flat, A, and C weighting... and octave filters at 125Hz, 250 Hz, 500Hz 1 kHz, 2 kHz, and 4 kHz
-- Data can be stored to a log file and transported to a PC for manipulation and display

Polarity:
Using the IE-33's built in signal generator (3.5mm stereo jack) or using a separate compatible generator (CD with compatible pulse comes with IE-33 purchase), easily check polarity of distributed and other speaker systems acoustically and electrically.

Scope:
-- Allows visualization of wave forms
-- Standard and XY
-- Dual trace

Signal Generator:
-- Pink noise
-- White noise
-- Sine waves
-- Square waves
-- Triangle waves

Audio Level Volt Meter:
-- Large analog and digital display
-- User selectable scale
-- Measures AC Volts, dBu, dBV and AC V
-- Detectors: fast, slow, peak, impulse
-- Selectable weighting filters: Flat, A, and C weighting... and octave filters at 125Hz, 250 Hz, 500Hz 1 kHz, 2 kHz, and 4 kHz

Downloading to a PC:
Since the iPAQ operating system is Microsoft® Pocket PC®, measurement data in storage registers can be easily downloaded to a PC by using Microsoft ActiveSync® software (included with any IE-33 purchase). Files are stored in tab-delimited format and are viewed using IvieXLS graphic software (for use with Microsoft Excel® or any other compatible means).
