Keysight Technologies 58503A

The Keysight (Agilent) 58503A is a GPS time and frequency reference unit engineered for applications requiring high-precision timing without the need for a primary frequency standard. It delivers 10 MHz and 1 pps outputs with exceptional stability, driven by SmartClock™ technology and a precision quartz oscillator. The unit offers frequency accuracy better than 1 × 10⁻¹² over a one-day average (0–50 °C), with a 6-channel parallel tracking GPS engine. Output amplitude exceeds 1 V p-p into a 50 Ω load, and control is facilitated through an integrated RS-232 interface. Ideal for telecom, broadcast, and scientific systems, it ensures long-term frequency accuracy with cost-effective integration. Testwall can supply the used Keysight (Agilent) 58503A, fully tested. With expert support and global delivery, Testwall ensures high-performance instrumentation with unmatched reliability and service quality.
