Oscilloscopes, logic analyzers LogicDAQ

The LogicDAQ system communicates with PC via USB 2.0 interface in High Speed mode, thereby achieving the maximum data transfer of 480mb/s. The device is powered directly from the USB port. With regard to notebooks with a smaller output current, the set can be optionally equipped with an external power supply. LogicDAQ is a device capable of recording and generating digital signals using 32 channels. The maximum sampling frequency is 400MHz device with the analog input bandwidth of 100MHz. Integrated modes of the logic analyser and the digital signal generator allow simultaneous observation of activations produced by a device along with recording any other external signals. Wide input voltage range and analog bandwidth enable measurements of signals of different electrical standards. Thanks to the latest FPGA systems, remote update of device firmware is enabled.

Navigator of measuring windows

DAQ2 software has a navigation window for running measuring windows for different devices of DAQ2 family. Thanks to the specialised navigation window, the user can make measurements with several DAQ2 devices at once or run a single device in several measurement modes simultaneously, with different configuration settings.
Individual configuration settings can be saved as separate files on the disk, so that they can be easily restored and the device can be restarted according to the priorly saved configuration. In the navigation window, using the device selector, it is possible to start a measuring window in one of available modes. The device selector shows all DAQ2 devices which are connected to a computer at a given time, including any available options and the size of RAM memory for each device. In addition, in this window there is an information console that records all actions that are performed between connected devices.



Signal measurements window

DAQ2 software has a combined window for observation of analog* and digital signals at the same time. Very ergonomic set of measurement cursors allows for flexible measurements on horizontal and vertical axes. Additionally, various magnifications (Zoom) of the recorded signal can be carried out as well as access to the analog* level trigger can be gained simultaneously for ’A’ and ’B’ channel.
The combined window allows for synchronous observation of recorded signal waveforms and the relationship between them. Moreover, signal from the Logger module is displayed here as well as signal recorded by the Pattern Generator module.

(*) - measurement of analog signals is possible only in case of ScopeDAQ i ScopeLogicDAQ instruments.



Triggering conditions

LogicDAQ works in the following operating modes:

  • Auto - digital waveform is generated and recorded cyclically
  • Single - digital waveform is generated and recorded one time after the trigger
  • Repeat - digital waveform is generated and recorded cyclically after the trigger
  • External - digital waveform is generated according to the external clock signal sent to the ’AUX’ input


The device trigger system device is a 2-level system. Each trigger level can be set with independent triggering conditions. Additionally, the trigger can be delayed (Capture Delay) after the appearance of a specific trigger by setting the time interval measured from appearance of a specified triggering condition.

The trigger can be set to one of two levels: ’1’ and ’2’:

  • Level1 - trigger according to Level ’1’ setting
  • Level2 - trigger according to Level ’2’ setting
  • Level1 or Level2 - trigger according to Level ’1’ setting or Level ’2’ setting
  • Level1 then Level2 - trigger according to specified order: level ’1’ and then level ’2’. In addition, it is possible to set time interval between Level ’1’ and Level ’2’.


Available trigger modes within each level:

  • Edge - Trigger on edge detection: rising, falling, any. It is also possible trigger after registration of a certain number of edges on any channel Edge Skip
  • Pattern - Trigger after registration of a defined sequence of signals (’1’, ’0’) with the ability to determine its length.
  • Edge AND Pattern - Trigger in case of compliance of product of conditions
  • Edge OR Pattern - Trigger in case of compliance of sum of conditions
  • External - Trigger with edge on extra I / O (AUX)
  • Force - ’manual’ trigger forced by the user at any time


Under normal operation the user can take advantage of the Pre/post trigger slide located in the Options tab, which divides memory intended for recording the measured signal into two parts. The Pre trigger part is used to record signal before a particular trigger condition appears; the Post trigger part is used to record signal after a defined trigger condition appears.



Pattern Generator, generator of digital signal patterns

The 32 channels of the LogicDAQ device may be either input lines of the analyser or the output lines of the digital signal generator. Pattern Generator implemented in the LogicDAQ system is a unique hardware solution that allows for simultaneous generation of digital signals and recording them to the analyser memory in real time. Such an implementation gives the user the possibility of real-time analysis of both signals generated and signals received by the device. The user also has the ability to trigger themselves from any lines, on which Pattern Generator is defined; additionally, there is a possibility of triggering from any combination of Pattern Generator signals or from any analyser line. Available Pattern Generator output voltage levels are: 3.3V, 2.5V

Pattern Generator works in the following configurations:

  • 16-bit configuration allows for generation of any sequence of signals on 16 lines of the analyser
  • 8-bit configuration allows for generation of any sequence of signals on 8 lines of the analyser; the other 8 lines may be used to record digital signals


Pattern Generator has the following modes:

  • Auto - digital waveform is generated and recorded cyclically
  • Single - digital waveform is generated and recorded one time after the trigger
  • Repeat - digital waveform is generated and recorded cyclically after the trigger
  • External - digital waveform is generated according to the external clock signal sent to the ’AUX’ input



Logger, digital signal recorder

Thanks to the unique solutions implemented in the FPGA systems, LogicDAQ allows for continuous recording of 32 digital channels to the computer hard drive with a sampling rate up to 5MHz. It depends on the size of memory inside the analyser, as well as the capabilities of the PC, to which the device is connected. Recording can be completed automatically after a certain period of time, when an error occurs or a specific disk space is used.
The rate of transfer of data to the computer and the time of recording of data to the hard drive is dependent on computer parameters and the operating system. During recording, the user can set parameters of refresh rate of the screen displaying the signal. In addition, the measurement time and the current logger’s file size is displayed on a regular basis.
After the login process, it is possible to view the recorded file with samples of the signal for thorough analysis. Recording can be carried out in any of the available modes of operation.



Saving data to files

Recording data representing the measured electrical signals can be realized on two ways. The first is the registration data directly to a computer hard drive in a continuous mode, using Logger. Another method is to record the data measured by the device and stored in the internal memory of LogicDAQ. In this case, the data stored in the buffer can be saved in the following formats:
* .dad, * .csv, * .txt, * .jpg, * .png

The data stored in files * .txt and * .csv file can be easily imported and analysed in external programs such as LABWieV, or other applications, depending on the needs of the user.



AUX input and output

LogicDAQ has a configurable ’AUX’ terminal, which can be both input and output, depending on configuration set by the user. The ’AUX’ output mode:

  • Generator output - rectangular signal generator output signal of adjustable frequency and amplitude (3.3V or 2.5V)
  • Trigger output - internal trigger signal output
  • Buffer full, post trigger - output issuing signal, which indicates that signal recording memory is full


The ’AUX’ input mode:

  • Trigger input - input for external trigger, set both for the rising and falling edge of the signal
  • External generator clock - input for external sampling clock, according to which signals are to be recorded


’AUX’ input output is a convenient solution in cases when it is necessary to quickly produce a signal of known frequency and amplitude in the measurement system, or to couple the device with another DAQ2 device or another measurement system.
