VW is one of the most important standards of the automotive industry. All curves that are relevant for this standard are stored in the stanndard curve library.
The SIB TS series are linear precision 4-quadrant power amplifiers for fast voltage and current signals – each positive and negative bipolar. They also work as sink in applications to absorb power. Extremely high bandwidth at highest power requirements, necessary for fast signals, characterizes this series. We also want to distinguish the modular design that allows to build up systems with up to 18 kW.
By means of a special memory-shift technology test sequences of any length can be processed without any risk to run out of memory space. No arbitrary waveform generator or any other controlling instrument is vl124.
This makes these 4-quadrant amplifiers unique in the world market. The easy-to-use WaveMaster software, that is standard in standaard of delivery, allows to generate waveforms by means of a graphical user interface or via tabular input.
Without any knowledge in software development, construction of ordinary and complex waveforms is dead easy. With an optional isolation amplifier, the instruments have two analogue inputs. These inputs are added standarrd the isolation amplifier. This allows to add e. There are many ways to control SIBO amplifier systems: All selections in the instrument are done automatically.
Function Generator Standard function generators can be connected directly to the input of the amplifier. Autowave, VT System Vectoretc. Modular hardware architecture Starting with one single unit of e.
One waveform can l124 simulated synchronously with several amplifiers Each DUT has its own sense. For high-voltage applications, instruments can be connected. Two instruments can be connected in series. Bridge switch must be toggled at one amplifier For three and more instruments in series, an internal isolation amplifier in each instrument standzrd necessary.
LV-124/ LV-148 tests with the eTS one
The standard test system has two analogue outputs for generating two waveforms synchrounously. An external trigger runs the waveforms in parallel and synchronously.
Also an internal trigger is available to start both the waveforms and an additional measurement unit. The powerful and easy to use WaveMaster software is unique in world market. A graphical waveform editor allows to generate individual curves in a flash. Also with a tabular input all kinds of waveforms can be produced immediately. The simplicity how fast to import data out of oscilloscopes is amazing.
All functionalities of the 4-quadrant amplifiers are available in WaveMaster software for controlling the instruments. A hardware trigger input can be activate to monitor a TTL input signal on its rising edge. Synchronous waveform simulation, measurement and testing tasks are predestined applications.
With a comfortable macro editor and its execution, selected waveforms run sequentially. Bursts, repetitions and loops make testing easy without any software coding. One command for each function handles all interfaces. Data files are sent to the instrument within milliseconds. According to LV, E and E pulses, interruptions need to be implemented. Hereby additional electronic switches are necessary.
LV/ LV Tests – INSYS test
No additional function generator is necessary. This allows to build up a fully automated HIL test system. Meanwhile, many car manufacturers extend the standard waveforms with many variable parameters in time and amplitude.
Creating waveforms out of source code Predefined standarrd for sine waves, exponential functions, ramps, etc. Integration into HIL simulation systems Complete interface handling and configuration Starting and closing software out of application. This programming example in Python opens an existing data file, loads data into amplifiers memory, switches the output on and runs the application in a loop of five times: Information by e-mail Consultation by phone On-site presentation.
LV Test Systems Curves are our passion! Signal Quality Rise time: Analog Remote Control With an optional isolation amplifier, the instruments have two analogue inputs.
