OAT-592 Automatic Audio Tester Successor model OAT-900
This tester is designed to automatically measure the characteristics of four kinds of audio products − handsets (a combination of receiver and transmitter), 2-channel telephone units (headphone driver unit and micro speaker), stereo headphones and microphones, and make automatic judgment in reference to preset allowance.
A Windows XP personal computer is used for simple system control.
Measured data like numerical data and frequency response curve can be reviewed later on as all measured data can be stored. Characteristics and statistical data can be printed with an optional printer.
Model name, measuring conditions and measured data can be stored on an external memory device (option).
OG-435 PROGRAMMABLE OSCILLATOR
This oscillator is designed for audio equipment testing. Sweep time, frequency range and output voltage are programmable or can be controlled manually.
OAT-691 Audio Tester Successor model OAT-900
This tester is designed to automatically measure the performance of microphones. Measured data and judgment are shown on a fluorescent display.
Measuring condition data of each product are kept on a memory card. This makes it possible to immediately start measurement upon card insertion and power on.
Corrective calibration based on a reference microphone speeds the measurements.
In addition to the total judgment indication, itemized judgments, measured values, total test number, fail number and fail rate are shown.
OAT-694 Audio Tester Successor model OAT-900
This tester is designed to automatically measure the performance of stereo headphones or headphone units. Measured data and judgment are shown on a fluorescent display. Measuring condition data of each product are kept on a memory card. This makes it possible to immediately start measurement upon card insertion and power on.
In addition to the total judgment indication, itemized judgments, measured values, total test number, fail number and fail rate are shown.
ODR-204 16-channel Data recorder Successor model OT-1009
This unit is designed to collect the voice coil temperature and driving voltage data which are measured with the OMT-105A or OMT-205A voice coil temperature meter to graphically display them on a conltrol PC.
OFV-550 Variable Band-noise Oscillator Successor model OFV-552
This oscillator can set cut-off frequencies for high-pass filters and low-pass filters as needed. This makes it possible to create desired band noises by using a built-in noise oscillator. When an external oscillator is input, the OFV-550 can be used as a band-pass filter.
OFV-551 Variable Band-pass Filter Successor model OFV-552
This variable filter consists of a high-pass filter and a low-pass filter whose cut-off frequency and slope can be adjusted within the specified ranges.
OST-726 Speaker Fo & Ze Meter Successor model OST-828
This appliance measures the Fo and Ze of the speaker automatically, and performs GO, NG decision and setting ranking selection in relution to measurable quantity and standard value.
It is possible to provide output to the thermal printer or personal computer.
OMR-107A True RMS Meter
This meter indicates true root-mean-square values within a frequency range from 2 Hz to 50 kHz.
OMR-107R AC Voltmeter
This voltmeter indicates true root-mean-square values and peak values within a frequency range from 10 Hz to 20 kHz.
OG-430A Speaker Test Oscillator with polarity checking
This oscillator can automatically perform loudspeaker polarity checking while testing the performances of the speaker. The oscillation frequency can be manually swept.
A digital output voltmeter and 20 W power amplifier are provided.
OG-431A Speaker Test Oscillator with polarity checking
This oscillator is designed to automatically perform loudspeaker polarity checking while testing the performance of the speaker.
Manual sweeping, automatic sweeping in a single or repetitive mode are available.
A digital output voltmeter and 20 W power amplifier are provided.
OS-445 Sound Pressure Meter
The OS-455 is designed for measurement of the sound pressure in a free sound filed. Measurement use a 1/2-inch condenser microphone.
OS-446 Sound Pressure Meter
The OS-446 is designed for a measurement of the sound pressure level (SPL) at high frequency region in a free sound field.
Measurement uses a 1/4-inch condenser microphone and preamplifier (OMC-97+AP-1159).
OS-447 Sound Pressure Meter
Frequency response is selectable between flat and weighting characteristics A.
