One of the highlights of ITI
instrumentation is the windows based control software. The software
actually operates in two modes.
- 1. Stand alone (with no signal capture instrument necessary)
- 2. Instrument attached
- While the instrument is required to begin
capturing data, the software can operate in a "stand
alone" mode. In this mode it is possible to review previously
collected data. Stored data files may be opened, displayed and
processed for analysis. This mode is provided so that technicians in
a field environment may email the data files back to their office.
Engineers and or technicians in the office can then view the emailed
data file and view it without the need of an instrument.
- When an instrument is attached, data
collection may then commence. All initial settings are selectable
from the "floating" window. See the sample at the right.
Settings such as sample rate selection, gain settings, number of
samples, etc. are all adjustable from this control windows. This
window may be "minimized" to gain full full screen
viewing. The "Help" menu is essentially a written manual
that will guide a new user through each process. ITI software is intuitive
and simple to use. Feel free to download the latest version of ITI
software. The software comes complete with actual sample data files.
The software is fully functional, but cannot be used to collect
data, unless an instrument is connected.
While the instrument is attached to the
standard PC via USB port, it may be operated in three various modes.
- 1. DSO
- 2. PC Direct
- 3. Automatic
- In DSO Mode, data is collected and
temporarily store in instrument memory. Up to 64K 12 bit words are
stored internally, which are then transferred to the PC via the USB
Port. Data is then processed and displayed for further analysis. In
PC direct mode, data that is collected is transferred back to the PC
in "real-time". Data sampling is accomplished at a much
lower sampling rate, but is directly relayed back to the PC without
using the instrument's internal memory. "Automatic" mode
is a convenient way allowing the windows control software to
automatically control the gain, time-base and other settings for
optimum viewing. If a signal is unknown, the user will not need to
continuously adjust the controls, as the software is intelligent in
this respect and will process the data for "best" display.
- Data Analysis
- ITI Control software performs many complex
data analysis functions. Besides being a DSO, ITI software also
performs analysis functions as FFT, Correlation, Arithmetic as well
as Repetitive Waveform restructuring. Click the FFT sample screen at
