HERO®power power amplifier especially for automotive tests on ECUs  (100Hz / 30kHz ...200kHz on the debited ECU)

In particular, we demonstrated live our new development for tests according to LV148 – E05, superimposed voltages 30kHz—200kHz, whereby we interpret this LV148-E05 in a practical way, namely that the voltage applied to the ECU should be stable, even under load fluctuations.

The standard says nothing about the measuring location and the load, but the measuring location should be selected at the DUT input (the proof in the unloaded state directly at the output of the generator / amplifier is not expedient).


Measuring technology

Measurement technology for electrical quantities

signal processing


Isolation measuring amplifier e.g. T303A:
measuring ranges ±0,2V—0,5V –1V– 2V…5kV
frequency range:  DC…300kHz;
Low Pass Filter: 100kHz  ………..



Special feature:

measuring case

High voltage for piezo actuators up to 6kV

2018 – Electronica 2018

Once again we were able to inspire a broad, international professional audience with our high-end amplifiers at our booth.

The new Trendsetting Power Amplifier System PA-LV124/148 for the various measurement tasks in the automotive sector was of particular interest, which we were able to present with its special features:

  • Signal Fidelity at the DUT
  • Complies with superimposed fault specifications - even under load on the DUT, not just at no load
  • Intuitive operation via Information Center on the front panel with the areas
  • Control for setting the desired confection via touch display
  • Measure to check and adjust the parameters
  • Info for general information
  • Remote interfaces – 2 x USB – LAN – WLAN

25th April 2018 – Presentation at the Power Analysis & Design Symposium

Rohrer GmbH, Mess- und Systemtechnik presented their HERO®power precision power amplifiers at this year's Power Analysis & Design Symposium of Omicron Lab. The focus was on the Bode 100, a helpful and useful measuring device to document the frequency and phase behaviour of amplifiers.

By the way... a trip to Munich is worthwhile

not only because of HERO®power from Rohrer:

Here we have put together some attractions of our Bavarian metropolis for you.
