VHIC 9260, 9 kHz to 120 MHz, Impedance converter to 50 Ohm


The VHIC 9260 is a low-noise impedance matching device designed for precise EMI measurements in automotive and industrial applications. With a high-impedance input and minimized capacitance, it ensures optimal signal integrity for emissions testing in the 9 kHz to 120 MHz frequency range.

Key Features:

  • High-Precision EMI Measurement – Designed for use with rod antennas or capacitive voltage probes, ensuring accurate emission assessments in compliance with CISPR 25 standards.
  • Seamless Integration – Features a 50 Ω output, making it compatible with standard EMI receivers and spectrum analyzers.
  • Exceptional Linearity – Ensures precise limit measurements with a maximum ±0.5 dB amplitude flatness and a voltage gain greater than 10 dB (50 Ω load).
  • Low Noise & High Sensitivity – Provides minimal noise interference, supporting FM band noise floor measurements with a 50 Ω load, as outlined in CISPR 25.
  • Reliable Battery Operation – Powered by 8 rechargeable NiMH cells (9.6V, 1900mAh), delivering up to 50 hours of continuous use. The optional charger enables fast 2-4 hour recharging.

User-Friendly Design:

  • LED Battery Indicators:
    • Green: Battery OK
    • Orange: Battery reserve
    • Red: Low battery – recharge required
  • Durable Construction: Aluminum housing ensures robust performance in diverse testing environments (-10°C to +60°C).
  • Compact & Lightweight: 105x125x50 mm, weighing 680 g, making it portable for field and lab testing.
  • Secure Charging System: Equipped with a fuse-protected charging input to prevent electrical faults.

The VHIC 9260 is an ideal solution for engineers conducting high-precision automotive EMI testing, ensuring compliance with international standards while maintaining low noise and high reliability.
