Pendulum - Model CNT-102 -Multi-Channel Frequency Analyzer

SHARE
The CNT-102 Multi-Channel Frequency Analyzer by Pendulum Instruments is designed for high-performance frequency and time-interval analysis in a compact bench-top format. It allows simultaneous tracking of frequency, phase, or time on two input channels, providing a notable resolution of 14 ps and an impressive measuring speed of up to one million results per second. With gap-free measurements and a 13-digit/s frequency resolution, it stands out for its ability to accurately capture minute time and phase changes across two parallel signals. An optional RF input extends frequency measurement capabilities up to 24 GHz. The product features a color touch screen for intuitive operation and supports remote interfacing via Ethernet, WLAN, or USB. Its design minimizes the need for multiple instruments by enabling detailed phase comparisons and simultaneous frequency checks across different test points. The device's adaptable configuration options include additional channels and timebase choices, appealing to a variety of technical requirements and budgets.

The Pendulum CNT-102 is a new affordable model in the CNT-100 family for super-performance Multi-channel frequency and time-interval analysis in a bench-top unit. You can track parallel frequency, phase, or time simultaneously on 2 input channels on the large graphic screen. These instruments feature gap-free measurements, and have 14 ps resolution, up to 13 digits/s frequency resolution, and a measuring speed of 1M results/s. CNT-102 outperforms any competing Timer/Counter/Analyzer on the market.

For even higher performance, please check our CNT-104S, a 4-input Multi-channel Frequency Analyzer with 7ps resolution and a speed of up to 20MSa/s.

The very-high single-shot resolution gives better insights into the design under test, faster results in phase comparisons between clocks, more accurate calibration, and allows capture of very small time/phase changes. Track and compare 2 parallel signals with 14 ps resolution/timestamp, at a speed of 1µs 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. The CNT-102 is also a high-performance Modulation Domain Analyzer (MDA). Thanks to the high speed of one million samples/s  on 2 parallel signals, very fast frequency or phase/time changes can be captured in real time. CNT-102 has a unique parallel and independent 2-channel design, plus an optional RF input going up to 24 GHz. Both  400 MHz channels perform parallel, independent, and gap-free time-stamping of the input signal. This allows for new measurements that earlier required many instruments, like phase comparison of 2 atomic clocks, without the need for a switch. Or comparing frequency or any pulse parameter simultaneously in two different test points, without any second instrument or moving any test cable or probe.

The 2-channel design enables 2 parallel frequency measurements. One CNT-102 can replace 2 existing frequency counters in a test system at a lower cost/counter.

Using the option 22/05 rackmount adapter, you will have 4 parallel frequency counters in a 19”, 2U high rack space.  You can choose between Ethernet, WLAN*, or USB** 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. Perform fast block measurements up to 170k meas/s. Test time is reduced compared to existing solutions, and time is money.

* Requires an external USB WiFi dongle

** Later availability. USB full SW functionality will be available as future SW upgrades for early purchased units
