摘要： A modulation error is detected every symbol data to generate a trigger signal. The present invention focuses that there are limited patterns of shifts from one symbol data to the next one of the digital modulation signal. Measured values of amplitude, phase and/or frequency of symbol data are latched and then values at the next symbol timing are predicted from the latched measured values using said feature. The predicted and measured values are compared at the following symbol timing. If the difference (error) is over an acceptable range, a trigger signal is provided which allows acquiring a modulation error by symbol data.

摘要： A signal generator generates amplitude noise on a selected segment of a test signal. A user interface is used for selecting a segment of the test signal and an associated power level for applying amplitude noise at a selected power level to the test signal segment. A signal processing unit compiles the selected power level of the selected segment with the test signal to generate digital data representative of the test signal with selected segments having amplitude noise. A waveform generator receives the digital data and generating a test signal output having amplitude noise at selected segments of the test signal. The method includes the steps of: selecting a segment of the test signal to add amplitude noise; selecting a power level for the amplitude noise; and applying the amplitude noise at the selected power level to the selected segment of the test signal.

摘要： A signal generator can control phase relationship between output signals of the channels without stopping clocks provided to the channels to enable the circuit operation fast. First and second channels 20 and 22 have signal generation blocks 10 and 12 that have clock phase shift circuits 26 and 28, memories, parallel to serial converters and DACs respectively.

摘要： A signal generation system maintains a phase relationship between output signals of first and second signal generators even when the sampling clock frequency is changed. The signal generators are coupled via a communication means including a dedicated cable where the delay amount of the communication means is known and fixed. The first signal generator provides sampling clock, sequence clock and trigger/event signals to the second signal generator and CPUs of the generators share information via the cable. When the frequency of the sampling clock is changed, the CPU of the first or second signal generator calculates the clock number of the frequency changed sampling clock equivalent to the delay amount of the communication means. A delay circuit of the first signal generator 100 delays the waveform data by one sampling clock based on the calculated value for adjusting phase relationship between the waveform data in the signal generators 1.
