Built-in battery option

The CNT-91 Frequency Timer/Counter/Analyzer, is the highest performance counter for measurement, analysis and calibration of frequency, time interval and phase. In production test systems, R&D, calibration lab, or in the field; the CNT-91 outperforms any counter on the market for speed, resolution, statistical analysis and processing capabilities.

The Pendulum CNT-90XL Pulsed RF Microwave Frequency Counter/Analyzer is an excellent tool for measurement, analysis and calibration of Microwave Frequency, Power, and Pulsed RF time parameters like pulse width and PRI. Whether in test systems, on the R&D bench, in the calibration lab or out in the field, the high-resolution and ultra-fast CNT-90XL is the state-of-the-art Microwave Counter/Analyzer.

The new pulsed RF option enables measurements of pulses down to 30 ns width, plus PRI/PRF, frequency in burst and power in burst making CNT-90XL ideal for radar test and calibration.

The Pendulum FTR-210R GNSS disciplined Rubidium & Time Reference is a multi-output Frequency Standard, with near Cesium-level stability, thanks to the GNSS control. There are 7 standard outputs (5×10 MHz, 1×5 MHz and 1×1 pps) that can be expanded with up to 4 extra outputs, plus a programmable 100 MHz pulse output option.

The GPS-12R/HS of frequency standard offers traceable Cesium-like stability at a very attractive price. Synchronized to the GPS satellite system, the GPS-12R/HS provides both short and long–term high time and frequency stability, assuring precision and accuracy.

Very high long-term frequency stability is provided from the built-in Cesium-controlled standards in the GPS-satellites, ensuring zero ageing of frequency reference over time. Very high short-term stability comes from a disciplined low-noise built-in Rubidium atomic clock.

The use of a Rubidium atomic clock ensures a minimal phase drift during Hold-over (if contact with GPS satellites are lost).
