Abstract
A device for testing performance of telephone headsets. The device performs reception, transmission, reception distortion, transmission distortion, reception limiting, and current consumption testing, as well as allowing these same tests with reverse polarity. The complete headset may be tested, or just the bottom or top units may be tested, as well as auxiliary power packs. The tester is designed to be used with any conventional headset, regardless of variations in the specifications, such as power supply. The tester may be programmed for an automatic testing mode.
Claims38
An apparatus for testing a telephone headset having a microphone and a speaker, comprising:
- means for injecting a test signal into said headset, said injecting means providing a receive electric signal to said speaker and a transmit acoustic signal to said microphone;
- means for receiving an output signal from said headset, said receiving means capturing a receive acoustic signal from said speaker, corresponding to said receive electric signal, and further capturing a transmit electric signal from said microphone, corresponding to said transmit acoustic signal;
- and
- means for analyzing said output signal whereby various performance qualities of said headset may be ascertained, said analyzing means checking reception and transmission qualities of said headset by analyzing said receive acoustic signal and said transmit electric signal.
A device for testing various performance qualities of a telephone headset, said headset consisting of a bottom unit and a top unit, said bottom unit having one or more connecting jacks and having a first QD connector, said top unit having a second QD connector for connection to said first QD connector, and said top unit further including a microphone and a speaker, said device comprising:
- keyboard means;
- processor means responsive to said keyboard means;
- display means operatively connected to said processor means;
- and
- means for coupling said processor means to said headset, said processor means further including:
- internal memory means for storing processing data;
- means for injecting a receive electric signal to said speaker and a transmit acoustic signal to said microphone;
- means for receiving a receive acoustic signal from said speaker, corresponding to said receive electric signal, and a transmit electric signal from said microphone, corresponding to said transmit acoustic signal;
- and
- means for analyzing said receive acoustic signal and said transmit electric signal;
- whereby transmission and reception qualities of said headset are correlated to numbers which are displayed on said display means.
A universal headset tester for testing reception, transmission, reception distortion, transmission distortion, reception limiting, and current consumption of a telephone headset, said headset consisting of a bottom unit and a top unit, said bottom unit having one or more connecting jacks and having a first QD connector, said top unit having a second QD connector for connection to said first QD connector, and said top unit further including a microphone and a speaker, said universal headset tester comprising:
- a keyboard;
- processor means responsive to said keyboard, said processor means including:
- (a) internal random access memory for storing processing data;
- (b) means for injecting a receive electric signal to said speaker and a transmit acoustic signal to said microphone;
- (c) means for receiving (i) a receive acoustic signal from said speaker, corresponding to said receive electric signal, and (ii) a transmit electric signal from said microphone, corresponding to said transmit acoustic signal;
- (d) means for analyzing said receive acoustic signal and said transmit electric signal;
- (e) selectable gain means for providing said receive electric signal at varying amplitudes;
- (f) means for supplying said headset with first, second, and third power levels;
- (g) means for determining distortion of said receive acoustic signal and said transmit electric signal;
- and
- (h) means for measuring current consumption by said headset;
- first, second, and third unit type annunciators connected to said processor means, said first unit type annunciator being illuminated when both said top and bottom units are being test, said second unit type annunciator being illuminated when said top unit only is being tested, and said third unit type annunciator being illuminated when said bottom unit only is being tested;
- first, second, and third power annunciators connected to said processor means, said first power annunciator being illuminated when said first power level is being supplied to said headset, said second power annunciator being illuminated when said second power level is being supplied to said headset, and said third power annunciator being illuminated when said third power level is being supplied to said headset;
- an alphanumeric display panel connected to said processor means;
- first, second, third, fourth, and fifth units annunciators connected to said processor means for indicating units of numbers displayed on said display panel;
- a test port connected to said processor means;
- a multi-wire cable having first and second ends, said first end connected to said test port;
- and
- a remote test head comprising;
- a cable connector for receiving said second end of said cable;
- a first acoustic coupler for attachment to said microphone of said top unit;
- a second acoustic coupler for attachment to said speaker of said top unit;
- first connection means for receiving said jacks of said bottom unit of said headset;
- and
- second connection means for receiving either said first or said second QD connectors, each of said first and second acoustic couplers and said first and second connection means being attached to said test head and being connected, through said cable and said test port, to said processor means.
