The R&S HM8123 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.
