Type 1600F      Anechoic Chamber Free Loudspeaker Test System

Main Functions

The following items of loudspeaker can be measured :

(1) Frequency response     (2) Sound pressure sensitivity at 1 kHz (1 kHz can be changed)     (3) Average sensitivity of sound pressure within a frequency range     (4) Polarity     (5) DC  Resistance (DCR)     (6) AC Impedance (ACZ)     (7) Distortion at 6 points     (8) Fo     (9) Qe     (10) Qt     (11) Qm     (12) Automatic PASS/FAIL judgment of above items (1) to (8)     (13) Curve of distortion against frequency     (14) Curve of distortion against SPL     (15) Curve of AC impedance.

Note : Type 1600F can test the Loudspeaker Unit only.

Item

Model No.

1.

160 A

 Electroacoustic Analyzer

Mainframe. To control  and process the input、output signal.

2.

Monitor &

Keyboard

 High Resolution Color Display Monitor & Keyboard

Display the tested results & data and key in data. User may buy these two items at his local market, since price is cheaper and can save freight charge and import tax.

3.

171

Electroacoustic Testing Adapter

Combines with 160A mainframe, to test the freq. response curve、 sensitivity、 impedance、 Fo、 polarity、 distortion 、  parameter etc. of the loudspeaker 、 headphone 、speaker box.

4.

8120HF

Measuring Microphone

Its frequency response curve is very flat、precise and stable, can test the freq. response curve and sensitivity of the loudspeaker, or can be used as a feedback microphone.

143B

Test Box 

Combines with 160A and 171 mainframe,  the freq. response curve、 sensitivity、 distortion curve of the loudspeaker can then be tested even without an anechoic chamber , test result is the same as the one done in a standard anechoic chamber using a JIS test box.

6.

X-Y Mouse

Mouse

Replace the upward, downward, leftward, rightward and enter keys on the keyboard.

HP Printer

( Option )

Printer (All the HP DeskJet or HP Laser Printers that are supported by DOS can all be used.)

Print out the tested results & data.

Speed for testing one loudspeaker of Type 1600F :

When full automatic test mode is chosen, only 5.9 seconds are required for testing the all 11 item (listed below), including the display of all measured results and the judgment of PASS/FAIL (1/12 Oct, 20 Hz to 20 kHz). Note: 5.9 seconds is only a typical value, in fact, its test speed is related to the Fo value of the under testing loudspeaker and the tested width band.  

Automatically and continuously testing: (1) Frequency response; (2) Sound pressure sensitivity at 1 kHz (1 kHz can be changed); (3) Average sensitivity of sound pressure within a frequency range; (4) Fo; (5) Polarity; (6) DC  Resistance (DCR); (7) AC Impedance (ACZ); (8) Qm; (9) Qe; (10) Qt; (11) Automatic judgment of PASS/FAIL of above items 1 to 7.

★The frequency response and distortion of a loudspeaker measured and printed out by 1600F are the same as those measured according to JIS or CNS standard in a large anechoic chamber.
