Super fast counter timer streams ahead

Both speed and resolution have been improved over the existing market leader, the CNT-90. Now with unprecedented performance, the CNT-91 features 50ps single-shot time interval resolution; 12digits/s frequency resolution; an exceptionally fast 250,000 measurements/s saved to internal 3.5Million results memory; and an expanded 2,600 individual measurements/s via GPIB/USB bus.

Of particular interest is the ability to continuously stream data during the measurement process, and combined with the high speed, makes the instrument ideal for production test applications. Further, zero-dead-time frequency and period are standard features, allowing for accurate measurement and analysis of signal stability and Allan deviation calculations.

The high-resolution time and frequency measurements combined with 0.001° (phase measurements), make the CNT-91 particularly useful for detecting small, time and frequency changes, vital for R&D as well as production test applications. An optional TimeView program converts the instrument to a modulation domain analyser, taking advantage of the high-speed measurements and massive store to capture very fast frequency changes in real time.

The CNT-91 includes the ability to program a pulse output from 0.5 Hz to 100 MHz for defining pulse rate frequency (PRF). The wide frequency
range to 20GHz ensures the counter timer is eminently suitable for most carrier wave and microwave frequency measurement needs.

The menu-based graphical user interface ensures the instrument is quick to program and easy to use. The clear graphical displays show distribution histograms, trends and modulation domain information, which speed interpretation of random signal distribution and measurement changes vs time, from slow drift to fast jitter and modulation. It displays up to 14 digits resolution, more than most other interpolating counters, and along with auxiliary measurement parameters, obviates the need for additional instruments such as DVMs and oscilloscopes. USB and GPIB interfaces are supplied as standard.

Aspen is offering these Swedish designed and manufactured counter timers, available now on four week delivery, with prices starting at £2619. Applications include R&D, design, production test and calibration in a wide range of industries including telecom component and systems manufacturing and installation, oscillator manufacturing, precision calibration and metrology, and for automatic test equipment, as well as for specialist military, aerospace and defence applications.
