Abstract: Provided is a pseudo base station apparatus which allow a user to certainly acquire log data at a desired timing. A set-up unit 41 sets filter conditions and acquisition conditions. A first log acquisition unit 32A includes a first buffer 32Aa, which stores log data and updates the stored content when the buffer capacity is full, and acquires a first log data that a user wants. A second log acquisition unit 32B includes a detector 32Ba, which detects log data that coincides with the log acquisition conditions among the log data, and a second buffer 32Bb, which stores the log data detected by the detector 32Ba and constantly updates the stored content within the range of the buffer capacity, and acquires a second log data that a user wants.

Abstract: In an RBW filter, a bandwidth is set so as to selectively pass a frequency component of only a desired signal bandwidth of the measured signals that have been frequency converted into a normalized intermediate frequency signal. A waveform detector detects a signal that passes through the RBW filter. An A/D converter samples the signal detected by the waveform detector at a predetermined sampling rate at which a Nyquist frequency is within the frequency bandwidth of the RBW filter, thereby converting the sampled signal into digital data. A data storage section stores the digital data converted by the A/D converter. A signal processing section re-samples the digital data stored in the data storage section so as to reproduce a bandwidth of the detection signal of the waveform detector, thereby generating arbitrary time data.

Abstract: An A/D converter converts a to-be-measured analog signal to digital data while being sampled with a predetermined sampling frequency. A data sorting circuit sorts the digital data which is outputted from the A/D converter alternately into two signal paths and outputs them in parallel form at a ½ sampling frequency rate.

Abstract: A standby weft yarn cutting preventing device is provided for a multicolor fluid jet loom, such as a multicolor air jet loom. In cutting a picked weft yarn among a plurality of weft yarns with the cutter of the loom, the standby weft yarn cutting preventing device drives away the free ends of the rest of the weft yarns from the operating zone of the cutter to prevent the free ends of the weft yarns on standby from being cut together with the picked weft yarn.
