1600F

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.

*The fundamental combination of Type* 1600 F
Item	Model No.	Description	Usage
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	Electro acoustic 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.	8120H	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.
5.	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.
7.	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.

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.

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.
