- Design of an improved version of the laboratory Dual-Mixer
Time-Difference Multiplication (DMTDM) comparator for ultrasensitive
short-term frequency stability measurement. The new comparator, IPE4,
will enhance the measurement and calibration capabilities of the DMTDM
system compared with the previously built IPE3 comparator. It will have
comparable target background instability <7x10-15 at 1 s (≈25 Hz
bandwidth) and will allow switching between 5 MHz and 10 MHz input
frequency.
- Analysis of the influence of the temperature to the GPS receiver chain used for evaluation of the national time scale UTC(TP).
