The Agilent/Keysight 4193A-Accys is an accessory collection that extends the measurement capabilities of the 4193A Vector Impedance Meter across in-circuit and out-of-circuit testing scenarios. These accessories enable precise impedance characterization of electronic components and assemblies from 400 kHz to 110 MHz.
Technical Specifications
The 4193A operates across a frequency range of 400 kHz to 110 MHz with 1 kHz resolution for spot frequency measurements. Impedance magnitude measurements span 10 mΩ to 120 kΩ with ±3.0% accuracy; phase measurements range from -180.0° to +180.0° with ±3.2° accuracy. The instrument employs a constant current test signal of 10 µA to 100 µA depending on the impedance range. High-speed measurement time is approximately 150 ms in fixed-range mode, with ranging time of 1.2 seconds. Temperature coefficients are ±0.02%/°C for impedance magnitude and ±0.02°/°C for phase, referenced at 23°C.
– Key Features
• 3½-digit display for impedance and phase readout
• Spot and swept frequency measurement modes
• Constant current source excitation architecture
• HP-IB (IEEE-488) interface for automated test systems
• Analog outputs for external data acquisition
• Temperature-stable performance across operating range
– Physical & Operating Characteristics
Power requirements: 100/120/220 VAC ±10%, 240 VAC -10% to +5%, 48 to 66 Hz, 150 VA maximum. Operating temperature range is 0°C to 55°C with maximum humidity of 95% RH at 40°C. Dimensions are 426 mm W × 178 mm H × 498 mm D; weight is 18 kg.
– Compatibility & Integration
The 4193A-Accys collection includes fixtures and probes designed for the 4193A platform: low-ground probe kits with spare pins, clips, BNC adapters, component mounting adapters, and probe sockets; test fixture adapters; spring clip fixtures; and binding post fixtures. These accessories support both automated and manual impedance measurement workflows.
