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.

## Technical Specifications

• Frequency range: DC to 550 MHz (with prescaler assembly)
• Measurement functions: Frequency, Period, Period Average, Time Interval, Time Interval Average, Ratio
• Input: 50-ohm high-sensitivity amplifier
• DVM mode: DC voltage measurement up to 1000 V
• Weight: 25 lbs
• Dimensions: 16 × 14 × 10 in

## Key Features

The prescaler assembly distinguishes the 5327A from lower-frequency variants, enabling measurements across a full 550 MHz span. High-sensitivity input amplification ensures detection of low-level signals without compromise. Time interval and period average functions support precise characterization of repetitive and single-shot events. Integrated DVM capability provides direct voltage readout for multi-parameter troubleshooting and characterization.

## Typical Applications

• Pulse-width measurement and analysis
• Time-critical frequency and period characterization
• Automated test system integration
• Multi-parameter device and circuit verification
