Cursor Measurement
Available cursors are horizontal, vertical, marker, degree or combined horizontal & vertical.

Automated Parameter Measurement
Measure up to 29 different waveform parameters in different time conditions, including:

  • Entire waveform
  • Per cycle
  • Between cursors
  • Cycle statistics
  • History statistics

Never Miss a Data Point
Capture data for up to 200 days using up to 2Gpoint memory and optional hard disk recording. The History Memory function saves previous trigger data for later search and analysis.

The dual capture function is ideal for long-term testing. Capture the important transient events at a high sample rate while recording steady-state data at a low sample rate. The DL850E automatically switches to a high sampling rate when the trigger condition is met.

Time Synchronization

Correlate data with important events using the optional GPS and IRIG timing functions. The DL850E internal clock and sample clock can be aligned to synchronize multiple systems in remote locations. Merge data sets using XViewer PC software for easier analysis.

Real-Time Measurement of Electrical Power - /G5 option

Get results faster with real-time signal processing for electrical power parameters. Trend calculations such as active power, power factor, integrated power and harmonics, using a dedicated Digital Signal Processor (DSP) that is able to calculate and display up to 126-types of electrical power related parameters in real-time. This enables the user to display raw waveform signals such as voltages and currents along with power calculated parameters and even the capability to trigger on all of them. Data updating rate up to 100kS/s. Trend waveforms of each order of harmonics, bar-graphs and vector displays can be displayed. Both RMS and Power analysis modes are available. Besides the powerful power calculations, the /G5 option also contains all the functionality of the /G3 real-time math option.

DL750E Real Time Measurement Of Electric

Gapless Real-Time Calculations

Taking advantage of the real-time calculations of power parameters allows engineers to create a high-channel count, time series data set of mixed signals including sensors, automotive serial bus data, and accessory analog and discrete inputs. This is ideal for such scenarios as:

  • Long-term monitoring or validation of power system performance over hours or days of testing
  • Fast transient evaluation while operating test vectors such as start-up, emergency shutdown, or vehicle simulated drive conditions
  • Using enhanced triggers to evaluate power parameters and trap unusual behavior for continuous improvement

DL850EV Vehicle Edition

The ScopeCorder Vehicle Edition is designed for engineers working in the automotive and railway industry, providing a thorough insight into the dynamic behavior of the electromechanical system. This integrated approach results in considerable time saving compared to using multiple separate instruments.

Powerful Real-Time Calculations and Analysis Functions

As a standard feature, the ScopeCorder is equipped with a set of basic arithmetic functions such as addition, subtraction, division, multiplication, Fast Fourier transformation and more. In addition to standard math, advanced real-time analysis functions are available.

Real-Time Mathematical Computations and Digital Filtering - /G3 option

Armed with a dedicated digital signal processor the ScopeCorder can perform mathematical calculations such as arithmetic operators with coefficients, integrals differentials, and higher order equations on acquired measurement data. The results of these calculations are displayed during waveform capture in real-time. In addition to mathematical operators, steep digital filters can also be selected to isolate or trigger on the amplitude of certain frequency components.

Measuring the electrical angle corresponding to the mechanical angle is important for understanding motor characteristics. The Electrical Angle operation enables the extraction of the fundamental component of current by Discrete Fourier Transform, then the calculation of the phase difference between it and the rotary angle in real-time. A trend of the phase difference can also be displayed in real-time.

DL850E Real Time Mathematical

User defined computations - /G2 option

With user defined computations it is possible to create equations using a combination of differentials and integrals, digital filters, and a wealth of other functions. Moreover, it is possible to perform various types of FFT analysis using two FFT windows. In applications such as vibration and shock tests, you can easily evaluate abnormal vibrations while simultaneously measuring other signals.
