LV124 aka. VW80000 is one of the most important standards of the automotive industry. With the 100-TS series BOLAB presents a globally unique solution for the simulation of on-board supply systems acc. LV124 / VW80000 and numerous other standards. All curves that are relevant for this standard are stored in the integrated curve library. The 100-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.
BOLAB´s arbitrary power amplifiers include a huge memory of 1.000.000 data points to store pre-defined arbitrary LV 124 waveforms in the instrument itself. 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 needed. This makes these 4-quadrant amplifiers unique in the world market.
The easy-to-use WaveMaster software, that is standard in scope 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.
(16 bit), 2,8 MS/s (optional 4 / 8 via external control unit)
With an optional isolation amplifier, the instruments have two analogue inputs. These inputs are added in the isolation amplifier. This allows to add e.g. an interference on a standard waveform. There are many ways to control BOLAB amplifier systems:
For high-voltage applications, instruments can be connected.
The standard test system has two analogue outputs for generating two waveforms synchrounously. An optional external control unit is available for 2 / 4 / 8 / synchronous output channels. Independent waveforms on each channel can be generated with BOLAB´s WaveMaster Software.
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. Without any knowledge in software development, construction of ordinary and complex waveforms is dead easy. 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. Read in ASCII data files is possible in the same way.
All functionalities of the 4-quadrant amplifiers are available in WaveMaster software for controlling the instruments.
Short time current on/off, output on/off, operating voltage range and other functions can be easily set with its USB interface.
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.
With the WaveMaster remote DLL´s, available for nearly all programming languages, with its command library, users control the 4-quadrant amplifiers in an absolute perfection.
There is no need to handle hardware interfaces such as USB or LAN. One command for each function handles all interfaces. Data files are sent to the instrument within milliseconds.
According to LV124, E-10 and E-13 pulses, interruptions need to be implemented. Hereby additional electronic switches are necessary. These switches are controlled by BOLAB´s WaveMaster software and the amplifier´s built-in counter outputs. 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. BOLAB´s comprehensive WaveMaster Software allows to do these variations easily.
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:
arbnet = ArbNetPY27.CreateObject()
serverIPAddress = 10.99.92.78
serverPortNumber = 700
fileName = F:\\Waveform1MV.and
openfileRet = arbnet.OpenFile(fileName)
source = NI DAQ USB-6259
amplifier = 105-75E-TS
setSysRet = sys.Set(1,source,amplifier,0,0,0)
run = sys.IsRun()
while run == 1:
run = sys.IsRun()
