Abstract: PROBLEM TO BE SOLVED: To improve reliability of data transmission, while ensuring real-time property of data transmission. SOLUTION: Data packets P(1)-P(9) transmitted from a root station 1 contain data block B(101) or others. A leaf station 2, when receiving a data packet P(3) from the station 1 and being unable to correct data errors in data block B(302), transmits to the station 1 a request for retransmission of the data packet containing errors and block number information CYCLE5 (including the header H as a single block) defining the number of a subsequent novel transmitting data (compression ratio). The station 1 retransmits the requested block and transmits a new block B(401) and B(402) by the subsequent data packet(4), and also transmits the other data blocks B(403) and B(404). In this way, new data is compressed to increase the number of retransmission for data blocks.

Inventor: TAKAHASHI TOSHIYUKI
IPC: G01R27/28
Filed: 2001-05-14
Abstract: PROBLEM TO BE SOLVED: To shorten processing time by simultaneously measuring harmonics to the n-th harmonics. SOLUTION: In the case of measuring the harmonics of a semiconductor device DUT, a contact of a switching means 10 is controlled in such a way as to switch to the side of a frequency multiplication mixing means 11 by a control signal from a processing device 2. A signal LO from an LO signal source 9 and a signal RF from the semiconductor device DUT are inputted to the frequency multiplication mixing means 11. The frequency multiplication mixing means 11 performs addition and subtraction on n-times the signal LO and a signal RF, and outputs an obtained value as an intermediate frequency signal IF. Only low frequencies of the signal IF are passed by an LPF and inputted to a transmitter tester 5. The transmitter tester 5 converts the signal IF into digital data and performs FFT analysis on the converted digital data.  By this, a harmonic component is isolated to analyze frequencies and levels.
