Home » 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

"TT&MS has always been ready to provide us with state-of-the-art testing and measuring equipment. Characteristic is that TT&MS offers an extremely good service, as well as extensive support in the specification and selection of the equipment. The employees are technically well versed, a valuable distinguishing factor compared to other players in the market. Moreover, this technical knowledge is accompanied by a constructive, solution-oriented and personal approach."
“I’ve known the people at TTMS for years. An open and honest relationship has developed in which we can say everything to each other, resulting in a short but powerful communication. This increases efficiency, both for me and for TTMS.
Ever since I developed monitors at Philips, we have been using their video protocol test equipment for our latest protocols. By listening carefully, TTMS and their manufacturers respond to our needs. The mutual benefit is that we get good support and they make better testers.
In my current developments and tests on Signify connected LED lighting systems, we use various power supplies, electronic loads and analyzers. If TTMS has something new that is of interest to me, they know that I am positively critical of it. I’m looking for reliable equipment that is easy to use and TTMS continues to keep an eye out for new possibilities. For many years now, we have had a pleasant cooperation that works both ways. They know the market well and know how to find the right manufacturers for the right equipment.”
