The Rohde & Schwarz / HAMEG HM8123 Universal Counter
The Rohde & Schwarz / Hameg 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.

We don’t buy measuring instruments, we purchase solutions for specific measurement problems. I like to buy from TTMS, given their knowledge of test solutions in power electronics. I hate sellers. TTMS helps us to make the right choice. They even come up with instrumentation from manufacturers they do not represent themselves. And always with the perfect service: they are not complicated and just arrange what is needed.

In my role within the calibration and quality lab, it is a continuous striving for quality for me. In order to ensure this, the right support from, amongst others, suppliers is essential. TTMS understands this like no other, and I have been doing business with them for years. If I need to describe the business relationship with TTMS, it would be that it’s both constructive and instinctive. The measurement instrumentation is reliable.
In addition to this, TTMS’ expertise of test and measuring equipment complements the STCA.
