Laboratory for Communications Engineering (LNT)

The lab for communications engineering (LNT) at FH Aachen is primarily focused on conducting research and development works in the area of wireless communications and related areas. We have available high end measurement equipment that can be used for reference measurements and certification tasks, too.

Besides basic research tasks we are able to develop prototypes or bring in our know how of practical circuit design in existing projects of our industry partners.

The following photos give a brief insight into the lab's possibilities.

The Lab is located on the highest floor of the building "Eupener Str. 70 (rooms E324/E325 and E316/E317). The photo on the right side shows our 3m dish antenna.

The LNT has 15 workplaces, equipped with PCs and various measurement equipment.

The 5 vector signal test sites consist of vector signal generators SMJ100A, SMIQs as well as vector signal analyzers FSQ8, FSIQs (all Rohde & Schwarz) and control PCs as well as oscilloscopes (here: Tektronix DPO4032). All occuring waveforms of modern communications systems up to LTE, UMTS, WLAN, DVB,... can be generated and analyzed (time and frequency domain measurements, modulation error rate, bit error rates and much more).

The photo on the left shows another vector signal analyzer (FSIQ3) which is primarily used for projects dealing with "software defined radio" (SDR) for signal analysis and troubleshooting. This test site is also used by students for lab exercises.

The lab owns three vector network analyzers (R&S and HP) for research and development tasks up to 20 GHz.

For troubeshooting in digital circuit designs we have two logic analyzers. The photo shows an Agilent 1683A.

The photo on the left shows our soldering site for SMD assembly including a stereo microscope.
