CRY5620 Microphone tester
CRY5620 Microphone Tester can test many types of microphones, such as electret and MEMS. This instrument adopts SCM control and combines digital-analog processing technology, signal set generation, signal processing and data display. It can display the sensitivity of a microphone at low, medium and high frequencies, as well as the microphone current. Featured by easy-to-operation, user-friendly setup interface, fast and accurate testing, it is ideal for production lines and metrological service organizations.

Product advantages
The hardware combines SCM control and digital-analog mode, and has an accurate frequency signal generation module, an excellent signal conditioning module and a dynamic display module of real-time data.
Low, medium and high test frequencies can be selected. It can quickly set indicators for determination, such as sensitivity, upper and lower limits for acceptable microphone current, and can output the result on whether a value is acceptable.
Product advantages
Meanwhile, it has analog and digital input terminals, and customers can choose based on test products. Each 10 dB will be considered as a measuring range, so meeting the test needs of various microphones.
The test data is displayed in more user-friendly units for analog and digital microphones. When the user selects the analog test, the default unit of such sensitivity test will be dBV; when the digital test is selected, the sensitivity test result will be displayed in dBFS by default.
