IS8002CDV Classic Data Viewer

Main and Zoom Displays

Xviewer's zoom function works in the same manner as that on the DL instruments; displaying the entire waveform and a zoomed subset of the waveform simultaneously. The waveform can be horizontally and vertically zoomed. Even large amounts of waveform data (More than 2GP with the DL950) can be viewed quickly. The zoom window can be automatically scrolled (with variable direction and speed).

Annotation

Comments can be added as needed, in any position, on the waveform viewer window. All comments, plus the waveform(s) can be printed as displayed.

History memory display

Using the DL series instrument's history memory, you can arrange and display thumbnails of multiple acquired waveforms. The selected waveforms are expanded and displayed in the Main screen; multiple waveforms can also be superimposed.

Cursors

Using cursors, you can display the measured values at the points where the cursors intersect the waveform. There are three types of cursors available: horizontal, vertical, and X-Y. If two cursors are displayed, the difference between the them can be calculated and displayed.

Waveform computation (available only with Math Edition)

Up to 32 math waveforms based on the displayed waveform data can be calculated and displayed. In addition to simple addition, subtraction, multiplication, and division, user-defined equations can be created using a large number of functions including: trigonometry, differentiation/integration, pulse width computation, and six types of FFT calculations. FFT analysis using up to 2M data points can be performed, and a wide variety of functions are available for frequency domain calculations such as power spectrum and transfer functions (amplitude and phase). Digital filtering (low pass, high pass, band pass) calculations for noise rejection and other applications are also included.

FFT Display

Frequency domain waveforms are displayed in a dedicated FFT viewer window.

Automated waveform parameter measurements

Parameters (characteristics) of the displayed waveforms can be automatically calculated and displayed. Up to twenty-six parameters can be selected. Calculation of the selected parameters is performed automatically and the measured results are displayed in a list (as shown on the left).
The results of these calculations can be saved in a CSV file.

Cycle Statistics and History Statistics functions, which are both available in DL series instruments, can also be available in Xviewer when the software version is 1.70 or later. A histogram of statistical result(s) can be displayed as well. The statistical result(s) can be saved in a .csv file.

Data conversion

Waveform data files in binary format (useful for data transfer because of their smaller size) can be converted to ASCII, Excel or Floating Point Decimal format and then opened using a spreadsheet program. It also can be converted into MATLAB(*.MAT) format file, then it can be imported into MATLAB.

Remote Instrument Control

Xviewer supports Ethernet, USB and GP-IB interfaces, allowing you to control DL series* instruments using the PC on which Xviewer is installed. A virtual image of the screen and front panel of the DL that Xviewer is connected to is displayed on the PC. You can perform operations remotely by using your PC's mouse to "click" keys on the virtual screen as if you were pressing the actual keys on the DL.

File Transfer

You can perform file transfers between a DL series * instrument and the PC on which the software is installed, via Ethernet, USB or GP-IB. When you connect with the DL, Xviewer displays a list of files residing on the DL. You can select files from the list for download to the PC.
