Microphone Verification and Calibration with UA-2115

LAN-XI UA-2115 Voltage Injection Calibration Front Panel supports microphone calibration and verification using VIC (voltage injection calibration) and CIC (charge injection calibration).  For VIC, combine UA-2115 with LAN-XI 3160 Input/Output Module and Microphone Preamplifier 2669-W-004, which is optimized for VIC.

Hardware connectivity includes 4× 7‑pin circular inputs, 2× BNC outputs, plus a turquoise LED indicator for VIC status.

Key benefits

  • Supports VIC and CIC
  • Industry-standard connectors
  • Extend intervals between equipment calibration
  • Turquoise LED indicator for VIC

Applications

  • Calibration of open-circuit voltage sensitivity of microphones using VIC
  • Verification of microphone measurement chain (microphone, preamplifier and cabling) using CIC

DAQ module compatibility

Connector and signal types

Connectors:

  • 4 × 7‑pin circular (F) connectors for input signal
  • 2 × BNC (F) connectors for output signal

Supported signals:

  • 200 V microphones

Notes

  • To choose the calibration mode, set the polarization voltage in the analysis software interface: 0 V for VIC and 200 V for CIC.
  • VIC is only available when using UA-2115 with LAN-XI 3160-A-042 and Microphone Preamplifier 2669-W-004. Preamplifier 2669-W-004 is specially designed to support VIC.
