Product profile
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 1.2×10-13 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.
Product feature
Background as low as 1.2×10-13/1S，2×10-15/1000S
Measured Input Frequency 1-30MHz, Standard InputFrequency 10MHz
