Name of operating software:  1600NHP  (Dual channel testing)       

Test mode: Uses dual channel input test at a different period of time.

Test object: ( 1 ) Testing the headphone without the microphone, similar to using 2 sets of Type 1600H.

Items of combination: 160N + 181C + 142ES (2 sets) + 142FS (1 set) --- Used for testing the headset   (See below figure).

  Or 

Items of combination: 160N + 181C + 142EH (2 sets) --- Used for testing the headphone.

( 2 ) Testing 2 receiver unit separately, similar to using two sets of Type 1600R

Items of combination: 160N + 181C + 142EA-S (2 sets) + 142F (2 sets)

( 3 ) Testing one receiver unit and one speaker unit at a different period of time, similar to using one set of Type 1600R and one set of Type 1600S

Items of combination: 160N + 181C + 142EA-S (1 set) + 142F (1 set) + 8120H

( 4 ) Testing two speaker units at a different period of time, similar to using two sets of Type 1600S

Items of combination: 160N + 181C + 8120H (2 sets)

　

Explanation: (a) The Model-142ES on the aforementioned item (1) can be replaced by Model-142EA-S, but if uses Model-142EA-S, then, Model-142FS can’t be used, user must prepare his own test jig, since Model-142FS is fit with Model-142ES only.

(b) Has analysis and statistics (Cp, Ca, Cpk) function

(c) Consists of LAN function, tested data can be uploaded to the Central Monitoring Unit

(d) PASS/FAIL digital signal output, can be linked with the automation installed by the customer

(e) Testable items:
