The Pendulum FTR-210R GNSS disciplined Rubidium Frequency & Time Reference provides near Cesium-level stability through GNSS-based disciplining. 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.
An optional input for frequency measurements to 400 MHz turns the FTR-210R into a one-box ultra-high performance frequency calibrator with up to 13-digit resolution in a second.
The CNT-102 comes as standard with a Gbit Ethernet interface for remote control and data transfer. Using a WiFi dongle in the front panel USB port, enables you to connect CNT-102 to your local wireless network. A USB 2.0 communication interface is HW ready from the start, with later full SW capabilities, via free future SW upgrade. You can access and control the instrument from your lab bench, or from anywhere in the world, using the integrated web server.
The FTR-210R disciplined Rubidium Frequency and Time Reference is operated manually on the bench via the 5” graphical touch-screen display. You can also connect a mouse, wired or wireless, to one of the front panel USB ports for easier operation.
When used as a GNSS disciplined Frequency standard, the short-term stability is very high, and ageing is virtually zero.
The optional measurement input converts the FTR-210R Frequency and Time Reference to a 1-box Frequency Calibrator. Using the MATH function, the Frequency of the device under test can be displayed either as absolute frequency, e.g. “10.000 000 01 MHz”, or as deviation from nominal frequency, e.g. “10 mHz”, or as relative deviation e.g. “1х10-9”.
The basic configuration contains 5×10 MHz, 1×5 MHz, and 1×1 pps outputs, to support other instruments, testers, or test objects. If that is not sufficient, 4 additional outputs can be fitted on the rear panel. These outputs are either:
The ultra-stable frequency reference, combined with the optional DC to 400 MHz measurement input, converts the FTR-210R Frequency and Time Reference to a complete one-box frequency calibrator.
The concept of traceability requires an unbroken chain of comparisons to international standards, on a continuing basis, where all comparisons produce documented results with stated uncertainty.
