Microphone Calibration System

Model 9350C

The Precision Acoustic Calibration Workstation Model 9350C is an accurate, turnkey, automated PC-based system that features cost-effective calibration of ¼", ½" and 1" microphone cartridges (open-circuit sensitivity), microphone cartridges with preamplifiers (closed-circuit sensitivity) and microphone Frequency Response Function.

In addition, the system provides for conformance testing of microphone preamplifiers and acoustic calibrators: pistonphones as well as speaker phone based calibrators.

Under complete software control, the 9350C operates in four modes:

• Microphone Cartridge Calibration
• Microphone & Preamplifier Calibration
• Preamplifier Conformance Test
• Source Calibration (example: pistonphone)

A calibration certificate may be generated, or the results may be saved in the database.

• Full Windows  98^® / NT^® and XP^® compatibility.
• Streamlined, easy and intuitive operation throughout.
• Comma Separated Variable (CSV) export of calibration data.
• Easy and fast retrieval of calibration certificates from a model/serial or asset number filtered list.
• Sophisticated system verification procedures.
• Automatic Free-Field and Random Incidence correction curves applied for those types of microphones.
• Pass/fail classification of the Microphone Under Test is available by use of frequency dependent limit lines.
• Automatic test parameter setup for PCB^®, Larson Davis, GRAS, and most Bruel & Kjœr and ACO microphones.
• Integration of customer defined logo on calibration certificates.
