The O-SCOPE Ie includes all of the
advantages of the Ip plus an external trigger
We have been designing and building PC-based
systems for several years. The O-Scope line of test and measuring
equipment began with the concept of adding T & M functions to
a PC. That concept became reality two years ago and was later
expanded. Now, O-Scopes are being used in place of conventional
data loggers, chart recorders, voltmeters, X-Y plotters,
frequency counters, spectrum analyzers and oscilloscopes. All
O-Scopes are engineered and manufactured in the Houston area and
distributed worldwide.
The O-SCOPE I is a pocket-size module which plugs into the
printer port, tranforming a PC (286 or higher) into a digital
storage oscilloscope. Included in the package are frequency
spectrum and data logging modes of operation. Working with a
desktop, laptop or notebook computer, displayed sweeps can be
captured on the screen, saved to disk, and output to a printer
via the DOS print screen function.
In the oscilloscope mode, sweeps are displayed on a 6 x 10 division grid which is six times larger than a typical oscilloscope grid. Each Sweep is based on 500 sample points. Operating parameters such as input range, sweep rate, and trigger level are displayed and easily adjusted through the computer keyboard. Also displayed are calculated voltages, frequency and period.
In the spectrum mode, sweeps of a selected frequency range are based on a 256 point FFT. The highest peak is automatically scaled to zero dB so that no peaks are cut off. Because of the logarithmic intensity scale, even low harmonic content is visable.
The O-SCOPE Ip includes all of the software upgrades which have been added since the O-Scope I was first introduced. Some of the more popular new features are: Delayed Sweep; Extended Sweep; Pause/Review Mode; Roll Mode; Disk Log View Mode; Four Cursors; Date and Time Stamps; Separate Driver and API for Programming.

O-Scopes offer several features not found in conventional analog oscilloscopes. First, they are small and lightweight; can be carried in toolkit or briefcase. Second, trace sweeps can be stored on the display screen indefinitely. Third, sweep data can be logged to disk files and loaded into other programs. Fourth, the spectrum analyzer mode provides a graphic display of the frequencies of the incoming signal. Fifth, captured sweeps can be output to a printer. Sixth, numerical values for frequency, period and voltages (DC, RMS, MIN, MAX, and PEAK to PEAK) are continuously displayed.
O-SCOPE II
The O-SCOPE II is a dual trace unit with an external trigger.
Like the O-SCOPE I, it converts a PC into a multi-function test
and measuring instrument. Information displayed on a desktop,
laptop or notebook computer can be captured on the screen, saved
to disk, and output to a printer via the DOS print screen
function. The O-SCOPE II design features simultaneous 2-channel
data sampling for accurate phase measurements in an X-Y
presentation.
Use of the O-SCOPE II provides a true full-function digital storage oscilloscope with bandwidths up to 250 KHz and sampling rates up to 1,000,000 per sec. The minimum PC required is a 286 with 12 MHz speed.
1. Dual Trace Storage Oscilloscope: The relatively large PC
screen displays traces on a 6 x 10 division grid along with
operating parameters and numerical voltage and frequency values.
2. Digital Voltmeter: Numerical values of
DC, RMS, MIN, MAX and PEAK to PEAK voltages for both channels are
continuously displayed.
3. Frequency Counter: The calculated values
of signal frequency and period are updated on each sweep for each
channel.
4. Frequency Spectrum Analyzer: Sweeps of a
selected range are presented on a calibrated graph with the
option of averaging. Screen capture, logging to disk, and
printing are other easily activated options.
5. Data Logger: In either the Scope mode or
the Spectrum mode, the sample points which make up a sweep along
with vertical and horizontal scales and other data can be saved
to disk. Up to 999 sweeps can be saved at the press of a key.
More sweeps, up to the capacity of the computer memory, can be
saved by creating additional files. This information is human
readable (ASCI format) and can be imported into other programs
for analysis, processing or printing.
6. X-Y Display Mode: Simultaneous 2-channel
sampling provides data for accurate display of phase
relationships between two input signals. Channel I determines a
point's vertical position while channel 2 determines the point's
horizontal position. The print screen function on a screen
capture will then provide an X-Y plot as long as 16 minutes or as
short as 500 usec.
