摘要： A method and apparatus for displaying a waveform on an error performance analyzer are disclosed. A repeated base bit pattern is received. Then, at a first time and for each incremental time thereafter for a predetermined period of time, multivalued voltage, VM, is determined. The VM is determined by constructing a bit error rate (BER) curve at the each incremental time. Each BER-curve spans a range of voltages from a low slice voltage to a high slice voltage. A derivative of the BER-curve is taken and absolute value of the derivative is used to determine the VM which is the slice voltage where the absolute value of the derivative curve is greatest. The apparatus includes a processor and storage with instructions for the processor to perform these operations.

The low frequency data can be captured in a very accurate, low cost, low bandwidth DC coupled path with ˜40 MHz of bandwidth. The remaining bandwidth (up to 20 or more GHz) can be captured with the IQ demodulator feeding the high speed ADCs.

摘要： A timebase establishes the timing of samples acquired by a signal sampler relative to a trigger signal that is synchronous with an input signal applied to the signal sampler. The synchronous trigger activates a first pair of samplers included in the timebase to acquire samples of a reference signal and of a shifted version of the reference signal provided within the timebase. A divider receives the reference signal and divides the frequency of the reference signal by a predesignated divisor, and a third sampler included in the timebase acquires samples of this divided reference signal, also according to the synchronous trigger. The samples of the input signal are acquired by the signal sampler according to the divided reference signal. A timing analyzer determines the timing of these acquired samples of the input signal relative to the synchronous trigger, based on the acquired samples of the reference signal, the shifted reference signal and the divided reference signal. Alternatively, the timebase is implemented according to a method that determines the timing of the samples of the input signal acquired from the signal sampler.

摘要： An optical fiber coupling system has high insertion loss repeatability. A lens expands the mode size of a source fiber connected to a test instrument or other source, reducing insertion loss sensitivity to positional and angular alignment of the bare input fiber with the source fiber. Index matching fluid reduces the effect of the cleave angle of the input fiber on insertion loss. The optical fiber coupling system is calibrated by substituting a through fiber of similar type and length in place of the input fiber. According to a first preferred embodiment of the present invention, a capillary tube contains the index matching fluid. According to a second preferred embodiment of the present invention, the index matching fluid is contained in a reservoir enabling optical signals to be coupled to optical components having multiple input fibers.

摘要： A data conversion system acquires samples of low frequency signal components of an applied analog signal at a first data conversion rate and samples of high frequency signal components of the applied analog signal at a second data conversion rate that is higher than the first data conversion rate. The data conversion system applies a first correction filter to the acquired samples of the low frequency signal components to provide a first filtered signal and applies a second correction filter to the acquired samples of the high frequency signal components to provide a second filtered signal. The data conversion system interpolates the first filtered signal to provide an interpolated signal, and sums the interpolated signal with the second filtered signal to provide an output signal.

摘要： A method and system characterize a random component of the jitter by designating an edge in the repetitive pattern, determining a slope of the designated edge, and acquiring a set of amplitude values at a different occurrences of the designated edge. A frequency domain representation of the set of amplitude values is then obtained, and identified peaks in the frequency domain representation are truncated. An RMS value, or other measure of random variations of the truncated representation is extracted and converted, based on the slope of the designated edge, to a corresponding RMS time jitter that represents the random component of the jitter. A periodic component of the jitter is characterized by determining the peak amplitude deviation of the acquired set of amplitude values, and then determining a periodic amplitude variation based on the RMS value, the peak amplitude deviation and the number of amplitude values in the set of amplitude values. The peak amplitude deviation is then converted, based on the slope of the designated edge, to a corresponding periodic time jitter that represents the periodic component of the jitter.

摘要： A method and apparatus for characterizing frequency response of a device under test (DUT) is disclosed. A repeated base bit pattern is received, the base bit pattern including a first transition from a 0-bit to a 1-bit. Then, using bit error rate distribution, multivalue voltage along the first transition is determined. Finally, the multivalued voltages are converted into frequency domain using fast Fourier transform. The apparatus includes a processor and storage with instructions for the processor to perform these operations. Using the present inventive technique, the frequency response of the DUT can be determined using an error performance analyzer such as a BERT.

摘要： An optical sampling method and apparatus use a probe pulse source of a predetermined optical wavelength range, e.g., 1560 nm, to sample incoming optical pulses in approximately the same wavelength range. The probe pulse source is frequency-doubled e.g., using a frequency doubler such as a nonlinear PPLN crystal, to obtain an intermediate second harmonic which may be filtered with a 780 nm bandpass filter to eliminate at least source frequency noise background. The filtered intermediate second harmonic is then mixed with the user input signal using an optional polarizing beam splitter and a dichroic beam splitter. The mixed signal is sent to a sum frequency generating (SFG) nonlinear crystal, e.g., a PPLN crystal, where the resulting frequency is near the third harmonic. The output from the SFG PPLN crystal may be filtered using a bandpass 515 nm filter to remove unwanted wavelengths and processed to measure/sense the near third harmonic content using a photomultiplier tube (PMT). Beyond the PMT, the output may be sent to a microprocessor for analysis and display on a cathode ray oscilloscope as necessary. 80-85% power conversion efficiency in the frequency doubler, a 60 or 65% photon conversion efficiency in the sampler and handling of 600+ GHz bandwidths, as well as background noise reduction are possible by using the invention.
