Introduction
Congratulations! With your purchase of the Ivie IE-33, or IE-35, you not only have one of the most powerful, ver-
satile, and accurate audio spectrum analyzers available, but you also have an analysis system that is capable of
expanding as your needs expand. The supplied microphone is a Type II microphone, making the standard IE-33,
or IE-35, a Type II measurement system. For those needing Type I accuracy, an optional microphone, pre-
amplifier and extension cable is available to convert either analyzer to a Type I measurement system. With rea-
sonable care, the IE-33 and IE-35 will provide a long period of useful service.
This manual is intended to familiarize you with the basic operations of the IE-33 and IE-35, and to whet your
appetite concerning some of its possibilities. It is in no way intended to be the total description of all the possibili-
ties of these units.
The IE-33 software runs on the HP© iPAQ© and requires an iPAQ 3950, or later jacket compatible model. (See
the IE-33 FAQ at www.ivie.com for a complete list of compatible iPAQ models). Pocket PC 2003 OS is required
and ActiveSync software Version 3.7.1 or later. The IE-35 software runs on the Dell® Axim® X50 or later model.
(The IE-35 is shipped with the Dell® Axim® X51v). Pocket PC 2005 is required and ActiveSync software Version
4.0, or later.
*******NOTICE!! IE-33 POTENTIAL DATA LOSS!!*******
The iPAQ, like all PDA’s runs on battery power. HP® is clear in their warnings about data loss if the battery is
completely run down. If you run the battery all the way down, your data can and will be lost! (This has a much
harsher sound if you’ve just completed a couple of days of taking measurements when the data goes bye bye!).
To guard against accidental data loss, a backup utility is included in the iPAQ software suite. This utility is easy
to use. You can schedule regular (even daily) backups that will happen automatically, or you can start backups
manually. The Sprite Backup utility included with the iPAQ will back up to the “iPAQ File Store” (an 8 MB non
volatile storage area in the iPAQ itself), or to an SD-style memory card that plugs into the iPAQ’s SD card slot.
Sprite also makes a separate backup utility which can be used to back up your iPAQ to the hard drive of your
PC. We recommend that you make provision for backing up your IE-33 data on a regular basis.
The IE-35 does not have this concern. It is based on the Dell® Axim® X51v which features “Retentive
Memory.” The IE-35 will not lose data, even if the battery is accidentally run down.
IE-33 Controls (IE-35 Controls are Further Detailed on Pages 8 & 9)
As demonstrated across the page, the IE-33 makes use of a number of different controls, both software and
hardware based. The controls can be divided into three categories: 1) Hardware Buttons, 2) Software Defined
Stylus Buttons and 3) Pop-up Menus. Like the stylus buttons, the pop-up menus are activated using the stylus.
Hardware Buttons (IE-33)
The IE-33 software defines the use of the iPAQ hardware buttons as shown across the page. The thumb button,
for example, can be used to take a memory "snapshot" when in the RTA mode. It is also used to pause or
resume taking samples when in the Average Continuous mode and to "add a single sample" when in the Memory
Trigger mode. These features are covered in detail in the section of this manual dealing with memory functions.
Stylus Buttons (IE-33)
The stylus buttons contain many of the most used features of the IE-33. They are clearly labeled and very intu-
itive. Some duplicate the function of hardware buttons, as in the Zoom In and Zoom Out functions, as shown in
the illustration on page 3. The stylus buttons allow selection of the RTA display in octave, one third octave,
