Abstract
A test and measurement system for a frequency-hopping communication system includes a radio frequency antenna structured to receive a signal from a frequency-hopping data transmitting device including at least two frames of data in which the at least two frames of data are sent at two or more unique radio frequencies, and a decoder structured to decode the at least two frames of data without prior knowledge at which radio frequencies the frequency-hopping device were to be sent. Methods are also described.
Claims20
A test and measurement device for decoding data sent from a first device in a frequency-hopping wireless communication system to a second device in the wireless communication system without the test and measurement system being part of the wireless communication system itself, the test and measurement device comprising:
- a radio frequency antenna structured to receive a wireless signal from one of the first device or the second device, the wireless signal including at least two frames of data in which the at least two frames of data are sent at two or more unique radio frequencies;
- a waveform memory to store the wireless signal as a waveform;
- and
- a decoder coupled to the memory and structured to decode the at least two frames of data from the stored waveform without prior knowledge of the two or more unique radio frequencies at which the first device sent the at least two frames of data.
A method of decoding, in a test and measurement instrument that is not a part of a frequency-hopping wireless communication system, at least two frames of data sent from a first device in the wireless communication system to a second device in the wireless communication system, the method comprising:
- receiving, through a radio frequency antenna, a signal from one of the first device or the second device, the signal including at least two frames of data in which the at least two frames of data are sent at two or more unique radio frequencies;
- storing the signal in a waveform memory as a stored waveform;
- and
- decoding the at least two frames of data from the stored waveform without prior knowledge prior knowledge of the two or more unique radio frequencies at which the first device sent the at least two frames of data.
