Laboratory for frequency stability measurements

Short-term frequency stability measurements (time domain):

Equipment:

• Ultra-stable 5 MHz BVA reference oscillators Oscilloquartz 8600-BC5GE.
• Time interval analyzer TSC 5110A.
• Laboratory comparators based on dual-mixer time-difference multiplacation with background noise of 5.5⋅10^-15 in terms of Allan deviation for averaging interval of 1 s at 5 MHz in 26 Hz bandwidth.
• Universal time interval counters Stanford Research SR620.

Phase noise measurements (frequency domain):

Equipment:

• Phase Noise Detector FSS1000E with modified Phase-Lock Loop (PLL) and the the background noise of L(ƒ=1Hz) = −145dBc/Hz, L(ƒ=100kHz) = −177dBc/Hz at 5 MHz.
• FFT Spectrum Analyzer Stanford Research SR760.
