DSO-101 USB 2-Channel Oscilloscope


Description

 

The DSO-101 is an USB-powered digital storage USB oscilloscope with dual 20MS/s inputs and a 2MHz bandwidth that is small enough to fit in your pocket. The DSO-101 packs some powerful features including a hardware preamp, adjustable digital triggering, and 32kB memory depth on each of the two 8 bit input channels. The DSO-101 is powered by an open-source graphical user interface for Windows, the MAC and Linux.

DSO-101

 

The DSO-101is a general-purpose two-channel oscilloscope for the teaching, development and debugging of electronic circuits. Channels A and B are sampled simultaneously and stored in oscilloscope memory before being sent for display to the host computer. Consequently, they are always time aligned and triggered from the same trigger signal. The oscilloscope timebase frequency is derived from a crystal oscillator, so it can be expected to be precise and stable.

A PC host displays a graphical user interface for the oscilloscope with frequency readouts, sliders, clickable buttons and various other controls. The PC connects to the oscilloscope hardware via a USB cable so that no other power source is required.

A Graphical User Interface program for operating the oscilloscope is provided on the accompanying CDROM. The program is written in the Tcl/Tk language. It is completely Open Source, so it may be modied and distributed freely.

The USB interface emulates a serial port so that the oscilloscope may be accessed as aserial port device.

Features

Vertical Controls

Each of the independently-sampled input channels features a full hardware preamp with seven input ranges from 50mV/division to 5V/division.

Timebase Controls

Examine a variety of different signals with a 21 step timebase from 50ns/division to 200ms/division.

Trigger Modes

Automatic, normal, manual and single-shot trigger modes are available.

Trigger Controls

Precise 8-bit digitally adjustable trigger level on either channel. Examine pre or post trigger events by dragging the timebase cursor.

Cursor Measurements

Use the on-screen cursors to measure waveform features. Time cursors allow the user to measure the period and frequency of waveforms. Voltage cursors allow the user to measure the amplitude of a waveform.

Automatic Measurements

The graphical user interface automatically measures the frequency, period, average, maximum, minimum, and peak-to-peak values for both input channels.

Screen Capture

The screen capture allows the user to take a snapshot of the scope graphic interface and save the results in JPEG or PostScript format.

Histogram Tool (Experimental)

The histogram tool allows the user to view the distribution of samples for each of the input channels.

Add Your Own Features...

Open source code and API allow you to add your own features, modify existing features, or rewrite the entire user interface.
