Home » Products » R&S HM8123 3 GHz Universal Counter
The R&S HM8123 offers high sensitivity and the frequency range runs up to 3 GHz.
Inputs A and B (BNC) have a measurement range from DC to 200 MHz; input C (SMA) has a range of 100 MHz to 3 GHz. The input impedance of A and B is adjustable at 50 Ω or 1 MΩ; sensitivity is 25 mV.
This instrument offers nine measurement functions, external gate and arming connectors. With 10 digits, the LCD provides an accurate reading of the measurement results. RS-232 and USB dual interface is standard and a galvanically isolated IEEE-1488 (GPIB) interface is optionally available. The instrument is easy to use, has a quick start-up and is quiet due to its fanless design.
The counter is available in two versions:
– HM8123 3 GHz Universal Counter, TCXO (temperature stability ±0.5 x 10-6)
– HM8123-X 3 GHz Universal Counter, OCXO (temperature stability ±1.0 x 10-8)
– HO85 OCXO temperature stability ±1.0 x 10-8 for HM8123, HM8134-3, HM8135, OCXO Installation only ex-factory
– HO880 IEEE-488 (GPIB) Interface

"The ABB Power Grids Jumet organisation is an innovative development and production facility of ABB that manufactures active filters and battery energy storage systems to support a stable grid. To test these systems we have acquired two Cinergia GE/EL +120kVA eplus units capable of doing grid emulation (AC + DC), operating as an electronic load (AC +DC) and being a battery emulator. We have experienced very good support from TTMS in obtaining these two Cinergia units. This included organising an on-site demonstration and supplying loan systems prior to the delivery of our final systems. This way we could start testing as early as possible. TTMS also organised training for the operators from the original manufacturer. This support allowed us to introduce the first battery energy storage systems even prior to the full delivery of the Cinergia systems."

“At the Energy and Environment department of the Faculty of Science, Technology and Medicine (FSTM) of the University of Luxembourg we do have different research projects related to green energy contributing to the development of eco-cities. As a long-standing partner of our research unit, TT&MS has proven that they are able to answer even the most complex questions in a professional manner. They have shown that they are always up to date with the latest technology and do not spare any effort to look at the application and even the situation on site. The exchange of ideas was always very pleasant and took place quickly. We look forward to further years of fruitful cooperation.”
