摘要： A sampler module is disclosed for use in a sampling waveform measurement device that samples subject signals and measures the waveform of the signals. The module is constructed by accommodating within a metal container: a laser diode driver circuit that receives laser drive sampling pulse signals from the outside and supplies pulse drive signals by a gain switching method, a laser diode that receives the drive signals from the LD driver circuit and generates optical probe pulse light, a sampling photoconductor that performs switching in accordance with irradiated light pulses and samples the subject signals, a condenser that focuses optical probe pulse light from the laser diode upon the photoconductor, and cooling temperature control means that maintains the temperature of the laser diode at a fixed temperature.

摘要： A trigger signal generation device restrains a jitter from being generated in a measurement result of light, such as terahertz light, that has transmitted through a device under test. The device includes a first photoelectric conversion unit that applies photoelectric conversion to a probe light pulse, a second photoelectric conversion unit that applies photoelectric conversion to a pump light pulse, a first amplification unit that amplifies an output from the first photoelectric conversion unit, and a second amplification unit that amplifies an output from the second photoelectric conversion unit. The device also includes a trigger signal output unit that outputs a cross-correlation of outputs of the first amplification unit and the second amplification unit as a trigger signal, and a period difference adjustment unit that adjusts a difference in periods.
