ES5335 – Arbitrary Signal PCIe Generator Board

The ETAS ES5335 Arbitrary Signal Generator PCIe* Board generates analog, pulse width modulated, and digital signals with specified frequencies, amplitudes and pulse widths. This allows for the simulation of angle- and time-based sensor signals.

Dear visitor,

please note that ETAS GmbH will no longer offer HiL-systems in the future.

As the product on this site is part of these systems, it is no longer on sale as of 30 September 2021.

Products already ordered will still be delivered until 31 May 2022. Software service contracts (SSP) can still be renewed for one year until 31 May 2023 and will then run until 31 May 2024 at the latest.

Extended hardware support, extended hardware engineering services, special agreements on on-site service packages or extended software and hotline services can still be negotiated until June 30, 2022 for a period even beyond 2024 as part of individual agreements.

ETAS Arbitrary Signal PCIe Generator Board ES5335

Due to the high precision of ±5 mV/16 bits and the high signal quality, the ES5335 is especially suitable for simulating speed- or angle-synchronous sensors such as knock, camshaft, and crankshaft sensors. Misfires and spark failures can also be represented accurately. Using the ES5335 board, it is possible to achieve extremely low total latencies (≤ 50 μs) between the driver, vehicle, and environment model (DVE model) and the output signal.

Front view of the ES5335

One ES5335 board provides six independent, galvanically isolated signal generators. For example, four of these channels can be used to generate four independent knock signals for up to 12 cylinders. Another example is the implementation of a modern crankshaft sensor with the detection rotational direction, as used in start-stop systems. Multiple ES5335 boards can be combined into a single group of 12 or more synchronized outputs.

The board provides 12 different signal waveform tables, which are available to all six signal generators. These waveform tables can be allocated freely amongst the six signal generators. Moreover, they can be switched and also be written in real time.

The ES5335 board fits seamlessly into the LABCAR architecture. A mixed operation with existing VME** boards is also possible.

Configuration and control of the ES5335 board is via LABCAR-OPERATOR, ETAS’s configuration and experiment environment for HiL testing.
