DSO-1000E/F Series – Four-channel oscilloscopes with bandwidth up to 250MHz

Conrad Business Supplies, a household name for the distribution of electronics items has added to its ever-expanding products a new set of Oscilloscopes made by Voltcraft. The oscilloscopes are four-channel, they are very well equipped and are particularly suitable for measurements in research and development departments, in laboratories and schools as well as for maintenance, repair and service tasks.

DSO1000E/F Series of oscilloscopes cover the bandwidths from 80MHz to 200MHz and provide the real-time up to 1GSa/s. Also, they have 7-inch color TFT LCD with a resolution of 800 x 480 pixels as well as Windows-style interface and menus for smooth operation. What’s more, the plenty menu information and the easy-to-operate buttons allow you to gain information as much as possible while measuring; the multifunctional knobs and the powerful shortcut keys help you save a lot of time in operation; the Auto Scale function lets you detect sine and square waves automatically. By using the three methods the oscilloscope provides (context-sensitive, hyperlinks, and an index), you may master all operations on the device in quite a short time so as to greatly improve your efficiency in production and development.

The digital oscilloscope is intended to be used for visualizing electrical magnitudes and signals. There are four independent input channels available for measurement. The measuring lead is connected to the oscilloscope via two BNC sockets. Integrated help system can be called upon the display. The signals measured can be displayed on display as well as on a PC when a USB cable is used. The oscilloscopes also have a USB interface for connecting an additional data memory, for example, a USB stick.

The Oscilloscopes can perform some of the following: FFT (Fast Fourier Transform), extensive trigger options, standard Oscilloscopes functionality, firmware loading from a USB stick, and many more. The available models of the oscilloscopes are listed below:

  • Model DA0-1084E :
    • 4 Channels
    • Bandwidth – 80MHz
    • Sample Rate – 1GS/s
  • Model DA0-1104E :

IkaScope: a wireless oscilloscope probe

Author: Maurizio Di Paolo Emilio

IkaScope is a wireless oscilloscope probe that allows to observe the change of electrical signals over time. The probe is a handheld device, portable and fits perfectly in the hand and pocket. By using high-speed Wi-Fi connection, IkaScope wireless oscilloscope probe communicates with laptop, tablet or smartphone to share the acquired data on the screen. The IkaScope wireless oscilloscope probe is compatible with the most popular mobile and desktop operating systems. The probe has a 200 MSPs ADC, Spartan 3 FPGA and adequate battery capacity (450 mAh). Energy saving settings and downtime moments manage the energy efficiency. The probe comes with a ground clip and a USB charging cable. Especially relevant is the patented ProbeClick technology of IkaScope: all electronic circuits are powered only when the the probe is pressed (figure 1). The probe tip is also used to start the data acquisition. ProbeClick technology allows to save power and measure without remembering to press the run / stop button of a classic oscilloscope.

The probe technology and user interface

ProbeClick represents a simple innovative mechanism to manage the data acquisition by probe tip. Simply by pressing the probe, the device starts data capturing and streaming process on the screen using the wi-fi connection. In addition, by releasing the probe, the acquisition stops and automatically the data is available in the storage/cloud (figure 2). IkaScope application is the user interface to capture, measure and analyze analog signals. From the download page you can download the latest version of IkaScope for your prefered Desktop OS.

ICP12 USBSTICK, A New Tool for Signals Control & Monitoring

iCircuit Technologies had produced the iCP12 usbStick, a mini size 28 pin USB PIC IO development board and a good tool for signal monitoring (as oscilloscope), data acquisition and circuit troubleshooting at 1mSec/Samples period.

The iCP12 usbStick is a PIC18F2550 based USB development board that comes preloaded with Microchip’s USB HID bootloader which allows users to upload an application firmware directly through a PC’s USB port without any external programmer. It provides access to its I/O pins through 0.1″ pitch headers. A slide switch is also provided on board to select the operation of the board in Bootloader or Normal mode.

The features of iCP12 are listed as following:

  • Mini size, easy interfacing, high performance and user friendly device
  • Used with PIC18F2553 28-Pin Flash USB PIC MCU
  • Excellent flexibility that allows user to expand the board with plug and play modules
  • Peripheral Features:
    • 13x IO Port (6x 12bit ADC pins, 2x 10 bit PWM/Freq/DAC pins)
    • Serial port emulation (UART Baud Rates: 300 bps to 115.2 kbps)
    • Supported operating systems (32bit/64bit): Windows XP ,Windows Vista, Windows 7, Windows 8, Windows 10, Linux, Mac OS X and Raspberry Pi
    • Maximum Voltage: 5Vdc
    • 100mA current output at VDD pin with over-current protection
    • 20MHz oscillator
    • Green LED – power on indicator
    • 2x LEDs (Green, Red) – status indicator
    • ICSP Connector – on-board PIC programming
    • Switch Mode Selection – Boot or Normal mode

The iCP12 usbStick board is shipped with a preloaded data acquisition firmware that emulates as a virtual COM port to PC. Thereafter, the communication between the PC and usbStick is serial. The firmware also supports basic I/O control and data logging feature. They provide a PC application named SmartDAQ that is specially developed to communicate with the usbStick and control its I/O pins, PWM outputs, and record ADC inputs.

SmartDAQ has a very friendly GUI with real-time waveform displays for 6 analog input channels. The time and voltage axes scales are adjustable. SmartDAQ can log the ADC data in both text and graphic form concurrently. One can utilize this feature to construct a low-cost data acquisition system for monitoring multiple analog sensor outputs such as temperature, accelerometer, gyroscope, magnetic field sensor, etc.

SmartDAQ v1.3 Features:

  • Sampling channel: 6x Analogs (12bits ADC/1mV Resolution) + 7x Digitals (Input/Output)
  • Maximum Sampling rate: 1KHz or 1mSec/Samples
  • Sampling voltage: 0V – 5V (scalable graph) at 5mV Resolution
