MAK-6630 is an Audio Analyzer which incorporates the measurement functions of distortion, relative Value, AC/DC level and frequency in a single instrument, and also is equipped with a low distortion audio signal source (DDS method).

FEATURES |
■ |
Owing to the adoption of the DDS method, the frequency changing speed is very fast, from 10Hz to 110kHz, and the audio signal is very high purity (-100dB at 80kHz LPF). |
■ |
In spite of one measuring system, 2-channel measurement can be capable due to the L/R signal selector circuit, and also UNBAL/BAL measurements are possible for BTL amplifiers. |
■ |
High-pass filter --- 100Hz, 200Hz, 400Hz
Low-pass filter --- 30kHz, 80kHz
Pre-Low-pass filter --- 15kHz, 20kHz
Weighting network (PSOPHO) --- IEC-AUDIO, CCIR/ARM, DIN-AUDIO standards, In addition to the above filters, a user-provided filter can be inserted by connecting it to rear-panel Input/Output connectors (EXT. FILTER). |
■ |
The reciprocal type high speed counter is equipped and the range is from 10Hz to 110kHz with ±5×10-5 |
■ |
The measuring range is from 0.03160mV to 100.0V in 7ranges and an accuracy is within ±0.4dB at 1kHz. The frequency range is from 10Hz to 110kHz. |
■ |
The mesuring range is 30mV to 100V fs and an accuracy is ±0.5% of full scale. |
■ |
This unit is capable of measuring distortion factors of the fundamental signal over the frequency from 10Hz to 110khz, and a high sensitivity 1.0mVrms range is provided for the dynamic range measurement of digital audio equipments. |
■ |
For AC level measurements, it is possible to display input levels as the relative value referred to a reference value. |
■ |
All operation functions provided on the front panel can be programmed up to 100 steps, and also the limit (GO/No-Go) judgment and memory auto-sequence functions are equipped. |
■ |
This unit is provided with GP-IB, RS-232C and EXT.I/O external control interfaces as its standard equipment so that it can be converted into an automatic measuring system. |
