Abstract
Method for testing a radio frequency (RF) data packet signal transceiver device under test (DUT) in which test data packets with varying power levels are transmitted to the DUT for testing the DUT while still ensuring that the DUT remains in receive (RX) mode and is prevented from searching for another data packet signal. Alternatively, in the event that the DUT becomes unresponsive due to searching for another data packet signal, multiple test data packets with sufficient signal power levels to ensure reception by the DUT are transmitted to the DUT to cause the DUT to cease searching for another data packet signal and return to RX mode.
Claims8
A method for testing a radio frequency (RF) data packet signal transceiver device under test (DUT), comprising:
- transmitting, from a tester, a tester data packet signal including a plurality of tester data packets with alternating portions having corresponding intervals of mutually higher and lower nominal transmitted tester data packet signal powers as transmitted from said tester;
- receiving, with said tester from a DUT, a DUT data packet signal including a plurality of DUT data packets with alternating portions related to respective ones of said alternating portions of said plurality of tester data packets, thereby defining
- a first ratio of said portion of said plurality of DUT data packets received by said tester and said related portion of said plurality of tester data packets having higher nominal transmitted tester data packet signal powers,
- a second ratio of said portion of said plurality of DUT data packets received by said tester and said related portion of said plurality of tester data packets having lower nominal transmitted tester data packet signal powers, and
- a ratio difference between said first and second ratios;
- repeating said transmitting and receiving of said alternating portions of said pluralities of tester and DUT data packets;
- and
- maintaining a cumulative count of said plurality of DUT data packets received by said tester and related to said portion of said plurality of tester data packets having lower nominal transmitted tester data packet signal powers during at least one of
- said first ratio equals unity,
- said first ratio remains substantially constant,
- said first ratio is greater than said second ratio, or
- said ratio difference is greater than a predetermined value.
