HP / Agilent 5327A 550 MHZ TIMER

The HP/Agilent 5327A is a precision timer/counter instrument designed for frequency and time interval measurements up to 550 MHz. Equipped with a prescaler assembly for extended frequency coverage, it delivers six distinct measurement functions and integrates directly into automated test environments. The 5327A combines high-sensitivity input amplification with versatile measurement capabilities, making it suitable for demanding pulse-width and timing analysis tasks.
