FT91 High-performance frequency stabilization Tester
Frequency Stabilization Tester
FT91 is a high-performance frequency comparator specially designed for high-performance atomic clock testing, which can realize any frequency point measurement of 1-30 MHz,and the additional stability can reach 1.2x10-13 at 10MHz,and this module integrates a high-performance special clock internally, which does not affect the performance of the actual measurement in case of any frequency difference between the measured and standard signals.
Applicable fields: metrology departments, crystal production plants, research institutes, time and frequency companies, universities, etc.
Important Features
- Background as low as 1.2x10-13/1S,2x10-15/1000S
- Measured Input Frequency 1-30MHz,Standard Input Frequency 10MHz
- Fast determination of the measured frequency, automatic start of the measurement
- Batch test systems can be formed with specific hardware and software.
