SENSITIVITY TESTING EQUIPMENT FOR RADIO SELECTIVE CALL RECEIVER

摘要

PURPOSE:To apply sensitivity measurement of plural receivers simultaneously and to reduce the test time by providing an operation electric field strength storage section storing an operating electric field strength of a test object and plural operation detection means. CONSTITUTION:A main control section 1 sets a call number to an encoder prior to the start of the sensitivity test (1). Moreover, a carrier frequency is set to a signal generator 5 (2). An electric field strength (a) is set to an electric field strength storage section 2 and the signal generator 5 (3). Then a call to a receiver 8 is started. The main control section 1 uses an operation detection section 9 to monitor the presence of reception reply operation of the receiver 8 (4). In the presence of the reception reply, the electric field strength (a) is read from the storage section 2 and the result is outputted to an operating electric field strength storage section 2 in relation with the electric field strength (a) with the receiver 8 making the reception reply (5). Then the electric field strength (a) is decreased (6), and the processing from the items (3) above is repeated. When no reception reply exists, the electric field strength (a) is read from the storage section 2 and the value is outputted externally as the sensitivity measuring result (7).
