Description Usage

1.

184

Electro acoustic Analyzer Mainframe. To control  and process the inputoutput 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.

142 EA-S

( or 142 EK-S )

Artificial Ear ( 142 EA-S = IEC - 318 )

Receives the sound generated from the receive.

4.

186

( Option )

Sorting Driver Please refer to Note 1 as below.

5.

X-Y Mouse

Mouse

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

6.

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.

Note :

1. Model-186  Sorting Driver   when combined for use with Model – 160A ( or Model – 184 ) mainframe and user’s automatic sorting machine, can perform the automatic sorting which totally can be divided into 14 ranks. The sensitivity sorting is divided into 12 ranks (which are the same as the number of rank for the sensitivity sorting on the testing screen); Frequency response ranked at 13th , while  the other testing items, like : The impedance, distortion, ECM current etc. of the unqualified items ranked at 14th (When the indicators  of the  1st~13th rank  did not light up, it belongs to 14th rank). Model-186 is very suitable for use in the automation for the receiver, transmitter and microphone factories.

2. The items that can be tested by 1840R is much more lesser than Type 1600R does, it can only test the frequency response curve and sensitivity of the receiver, but its test speed is faster.
