This unit

The HP/Agilent 53131A is a 225 MHz universal frequency counter/timer engineered for precision time and frequency measurements across laboratory, system integration, and production environments. This dual-channel instrument delivers 10-digit frequency resolution and 500 ps time interval resolution, with real-time digital signal processing enabling simultaneous analysis and measurement throughput up to 200 fully formatted readings per second via GPIB. The 53131A measures frequency, period, time interval, pulse width, rise/fall time, phase angle, duty cycle, event totalization, and peak voltage - supported by built-in statistics (average, min, max, standard deviation), automated limit testing with pass/fail indication, and configurable math functions for scaling and offset.

Technical Specifications

Frequency Measurement: Dual 225 MHz channels; optional third channel extends capability to 3 GHz, 5 GHz, or 12.4 GHz

Frequency Resolution: 10 digits per second

Time Interval Resolution: 500 ps

Measurement Throughput: Up to 200 measurements per second via GPIB

Input Impedance: Selectable 1 MΩ (≈30 pF) or 50 Ω

Trigger Level Range: ±5.125 V with ±(15 mV + 1% of trigger level) accuracy

Key Features

Real-time digital signal processing for enhanced speed and accuracy

Flexible triggering options for precise event capture

Automated limit testing with visual pass/fail status and external device trigger output

Analog display mode for at-a-glance measurement status

20 stored front-panel setups for rapid configuration recall

One-button access to frequently used functions

Typical Applications Frequency and period analysis, precision timing measurements, phase relationship characterization, pulse parameter analysis, and production-level limit testing with automated reporting.

Compatibility & Integration GPIB connectivity supports direct integration with automated test systems and data logging frameworks. Configurable setups enable rapid deployment across multiple test scenarios without manual reconfiguration.
