The Pendulum CNT-104R is a new concept for super-performance multi-channel frequency and time-interval calibration and analysis, in a bench-top unit. It is a one-box Frequency and Time Interval calibrator combining an ultra-stable 10 MHz Rubidium Frequency Reference with a 4-channel advanced Frequency Analyzer. You can calibrate up to 4 oscillators/clocks in parallel simultaneously on 4 input channels.
The optional GNSS control of the Rubidium clock eliminates the small ageing drift giving unprecedented accuracy in a compact one-box solution. On the large graphic screen, you can watch drift over time and frequency distribution, as well as traditional numeric and statistics parameters. CNT-104R has gap-free measurements, < 7 ps time resolution, 12-13 digits/s frequency resolution, and variable gate time setting from 50ns to 1000s.
The CNT-104R comes as standard with one 10MHz reference output with ultimate frequency accuracy to 1×10-12, 24h average, using the optional integrated GNSS disciplining of the Rubidium clock. The addition of a Pendulum FDA-301A Frequency Distribution Amplifier multiplies the number of outputs that can be distributed to 4, 8, or 12, depend-ing on the number of rear-panel installed output modules (1, 2, or 3).
The ultra-high resolution of 12 to 13 digits for 1s gate time gives faster and more accurate calibration results. With CNT-104R, you can track and compare 4 parallel signals with 7 ps resolution/timestamp, at a settable rate from 1000s down to 50 ns between samples in each channel. Gap-free, zero-dead-time counting provides back-to-back measurements without losing any cycle, even for very long measurements.
One of the great features of the CNT-104R is the graphic display with its menu-oriented settings. The non-expert can easily make correct settings, thanks to the guided instruction on most setting pages. Valuable signal information, given in multi-parameter displays, removes the need for other instruments like DVM’s and Scopes for quick signal verification.
Using the CNT-104R with the optional GNSS control, the 10 MHz frequency reference accuracy is 1E-12 averaged over 24h, day after day, forever. The intrinsic ageing of the Rubidium clock is totally eliminated.
The 4-channel design enables 4 parallel frequency measurements. One CNT-104R can replace 4 existing frequency counters in a test system at a lower cost/counter, plus provide an ultra-stable reference frequency to the test stand. 5 instruments-in-one-box. You can choose between Ethernet, or WLAN as a communication interface to a PC/Laptop/Tablet, or to the test system controller. High bus speed reduces test time in ATE test systems. You can perform fast block measurements up to 170k meas/s. Test time is reduced compared to existing solutions, and time is money.
The CNT-104R comes as standard with a Gbit Ethernet interface for remote control and data transfer.
