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.

摘要： A low frequency cross-over network is added to a DC coupled IQ demodulator. 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 apparatus for displaying an eye diagram on an error performance analyzer are disclosed. A first bit sequence is received and compared with a second bit sequence, the first bit sequence and the second bit sequence being substantially similar. For each delay increment for an entire clock period a bit error rate (BER) curve is constructed. The BER curve is then used to locate the bit voltage or bit voltage spread for the 0-bit and the 1-bit for a particular delay. This is repeated a predetermined number of times to cover an entire period. Then, the bit voltages or bit voltage spreads are displayed as an eye diagram.

摘要： A timebase establishes the timing of samples acquired by a signal sampler relative to a trigger signal that is synchronous with a signal applied to the signal sampler. A first pair of samplers included in the timebase acquires samples of a reference signal and of a shifted version of the reference signal provided within the timebase, according to a synchronous trigger, to establish a first time position on the reference signal. A second pair of samplers included in the timebase acquires samples of the reference signal and the shifted reference signal according to the synchronous trigger as delayed by a programmed time interval, to establish a second time position on the reference signal. While the programmed time interval is adjusted to designate timing of the sample acquisitions by the signal sampler, the two pairs of samplers in conjunction with a timing analyzer accurately determine the timing of these sample acquisitions based on the established time positions on the reference signal. Alternatively, a method determines the timing of the samples acquired from the signal sampler.

摘要： An optical cross-connect switch incorporates a pin grid actuator to selectively position optical elements relative to optical beams in the switch. A high density array of aligned, optically reflective elements is attached to the ends of independently selectable and moveable pins in the pin grid actuator. The pin grid actuator is the type extensively used in dot matrix printers. Linear motion of the pins causes the reflective element attached to the pin to intercept optical beams provided by input fibers coupled to the switch. Intercepted optical beams are redirected to designated output fibers, also coupled to the switch. A staggered arrangement of the input and output fibers equalizes all of the signal pathlengths through the switch, regardless of which pin in the pin grid actuator is selected. According to an alternate preferred embodiment of the present invention, multiple optical cross-connect switches are cascaded using a staggered arrangement of interconnecting fibers.
