Pendulum Instruments Introduces 4-channel Frequency Counter/Analyzer

The CNT-104S is a new multi-channel frequency analyzer released by Pendulum Instruments, a company specializing in time and frequency measurement, analysis, and calibration. It is the first benchtop unit to offer a 4-channel universal frequency counter (UFC) with the capabilities of a time interval analyzer.

The CNT-104S can simultaneously measure frequency, time, phase, and time interval error on four parallel inputs, allowing for parallel frequency measurements of multiple test objects or phase comparisons of reference clocks. The device offers a high level of performance with a time resolution of 7 ps, frequency resolution up to 13 digits/s, and a measuring speed of up to 20 million measurements/s.

The device features a user-friendly graphical interface that displays results numerically and graphically, with modulation/trend and value distribution graphs. Advanced graphic analysis enables smoothing of data and zooming in on individual samples. The standard frequency range is up to 400 MHz, with an optional RF input that extends bandwidth up to 24 GHz. Prices for the CNT-104S start below 10k€.

“We have successfully supplied our CNT-90 counter/analyzer range to demanding customers around the globe for many years now, and we have seen an increased request for more parallel measurements. And now, we are very happy to offer the first 4-channel frequency analyzer. The multi-channels, high resolution and speed should fulfill what our customers in high-end metrology, research and advanced R&D have been looking for. Furthermore, the CNT-104S will be a perfect solution for test systems requiring multiple frequency counters, like oscillator manufacturing, at an affordable cost, since one single CNT-104S can replace four traditional counters in the test rack, a big space and cost saving,” said Harald Kruger, global sales director of Pendulum Instruments.
