HP / Agilent 5363B Time Interval Probes

The HP/Agilent 5363B Time Interval Probes are precision measurement instruments designed for use with compatible time interval counters to capture accurate, repeatable time-domain measurements. Each probe assembly contains two channels capable of independent or paired operation as start and stop signal sources, enabling rise time measurements, propagation delay characterization, slew rate analysis, and phase jitter quantification with calibrated accuracy better than 1 ns.

## Technical Specifications

**Measurement Performance**
• Calibrated accuracy: <1 ns for rise time and propagation delay
• Effective bandwidth: 350 MHz (corresponding to approximately 1 ns rise time)
• Operating voltage range: ±10 V
• Trigger level adjustment: 10 mV steps from -9.99 V to +9.99 V
• Trigger edge selection: positive or negative slope
• Minimum pulse width: 5 ns at ±100 mV
• Input signal hysteresis requirement: 100 mV below and above trigger point for minimum 3 ns duration
• Maximum input voltage (damage level): 30 V

**Probe Input Characteristics**
• Input impedance: 1 MΩ shunted by <15 pF
• Input capacitance: <15 pF

**Power Requirements**
• Supply voltage: 100 V, 120 V, 220 V, or 240 V ±5% to -10%, 48–440 Hz
• Maximum power consumption: 30 VA

## Key Features

• Four measurement channels (two per probe) supporting independent or shared start/stop configurations
• Programmable trigger levels, slope, and polarity via HP-IB interface
• Rear-panel 50 Ω output connectors for start and stop signals
• Interchangeable probe tips for compatibility with Hewlett-Packard and Tektronix RF hardware
• Full remote programming capability with Option 011
• International safety compliance design

## Typical Applications

• Rise time and fall time characterization of digital and analog signals
• Propagation delay measurement across circuit elements
• Slew rate quantification in precision analog circuits
• Phase jitter and timing stability analysis in oscillator and clock circuits
• Time interval measurements between arbitrary signal events

## Compatibility & Integration

The probes interface with compatible precision time interval counters through rear-panel connections. HP-IB programming enables remote configuration of all measurement parameters except delay adjustment, supporting integration into automated test systems and data acquisition workflows.
