hybridNETBOX – multi-channel AWG and digitizer in one box
Grosshansdorf, Germany – September 16th, 2020. The hybridNETBOX is an exciting new instrumentation platform for applications that require simultaneous signal generation and acquisition. Six models are available offering the choice of two, four or eight pairs of matched AWG and digitizer channels, with output- and sampling- rates of 40, 80 and 125 Megasamples per second. With their ability to create and acquire electronic signals at the same time, these products are perfect for measurement systems that need to perform automated closed-loop or stimulus- response type testing. For example, they can reproduce and capture “echo” signals such as those found in Radar, Sonar, Lidar or Ultrasound. With their multi-channel capability, they can test these systems even when arrays of transmitters and receivers are used. The hybridNETBOX is also suited to ATE applications where components and
subassemblies need to be tested in a fast and automated way. They can quickly ascertain the functionality and tolerance of DUTs and UUTs (devices or units under test) by exercising them with numerous, easily adjusted, complex signals. This powerful testing process can be deployed in a host of applications like Bus testing, MIMO communications, circuit verification, mechatronics and robotics. Oliver Rovini, Technical Director at Spectrum Instrumentation, says: “We’ve created the hybridNETBOX series for engineers and scientists that require precise, simultaneous waveform generation and signal acquisition in manual, automated or remotely controlled applications. With these portable LXI instruments, we offer unique hardware and software capabilities allowing all users to match their specific testing requirements and also speed up their testing processes.” For accurate, low-noise waveform generation and acquisition, the units all use
the latest 16-bit digital to analog, and analog to digital, converter technology. All the channels are synchronized, sharing a common clock and trigger. The AWG channels can produce almost any waveform with signal amplitudes that go up to ±6 V into 50 ohm, or ±12 V into high impedance. Waveform output modes include Single-Shot, Loop, FIFO Streaming, Gated Replay and Sequence Replay. This permits the easy creation of test routines that can go from simple to complex. Meanwhile, the digitizer channels are designed to handle a wide range of input signals. They have variable input ranges that go from ±200 mV up to ±10 V, with fully programmable offset and selectable input impedance (50 ohm and 1 Megaohm). Both single ended and differential measurement modes are available. Like the AWG channels, they support a number of operating modes including Single-Shot, FIFO Streaming, Multiple Recording, Gated Sampling, and ABA (sample rate switching).
Next-gen Thermal Management Thermal Interface Material for Batteries in the field of electric cars The switch to electric drive systems and the increasing variety of sensors and electronics imply completely new challenges for the automotive sector. Besides the field of electric powertrain, the battery is one of the most critical parts of the EV or PHEV. A perfect temperature control is crucial and therefore, the selection and integration of thermal interface materials is mandatory. Of course, there are many different types of battery cells, modules, manufacturers and requirements on the market, which vary widely. That in turn leads to a lot of different thermal management solutions that can be applicated. A common solution can be, to transfer the heat of the cells to the bottom of the module and to connect these cells with a Gap Pad, which is compensating any kind of mechanical tolerances. The heat transfer from the cells to the bottom can be realized by a thermal tape, that combines a good thermal conductive with high electrical isolation. Furthermore, a thermal connection to the side of the module by a Gap Pad can be useful, to ensure a perfect cooling of the whole module. In view of these requirements, Kerafol offers a wide range of
different Thermal Interface Materials. For the Gap Pads, the focus is on thermal performance, softness and mechanical stability. It is important to know, that the thermal performance of the whole application is not only depending on the thermal conductivity of the pads, it is about the total thermal resistance of the construction. Besides the thermal resistance of the pad, there is always a thermal resistance between pad and heat source and heat sink. So it depends on the ability of the material, to get a smooth levelling and perfect contact to the surface. Of course the selection of the right pad depends on the application, but a very common solution can be the 86/225 or the 86/325, both based on silicone for the highest level of flexibility. For the thermal tape between the cells, the 86/60 can be a very good match, as this material combines a high thermal conductivity of 4,5 W/mK with an electrical isolation of 5 kV by a thickness of 0,25 mm.
