The VIAVI FireFly‑IIA delivers precise timing with ±30 ns RMS 1 PPS accuracy when GPS‑locked and frequency accuracy better than ±3E‑10 after three hours. Its OCXO‑based holdover maintains stability within ±7 µs over 24 hours at 25°C without motion. ADEV performance remains below 5E‑11 from 0.1 to 1000 seconds with GPS lock. Outputs include LVDS and RS‑232 1 PPS signals, plus two LVDS and three isolated +13 dBm sine‑wave 10 MHz outputs. The unit provides strong port isolation and supports full SCPI‑99 control. It uses a 50‑channel GPS receiver compatible with WAAS, EGNOS, MSAS, and is Galileo‑ready, with sensitivity down to −160 dBm for tracking and −144 dBm for acquisition.
