Signal Recovery 7265 DSP Lock-in Amplifier 7265 uses the latest digital signal processing (DSP) technology to extend the operating capabilities of the lock-in amplifier to provide the researcher with a very versatile unit suitable both for measurement and control of experiments. At the same time due consideration has been given to the needs of those users wishing only to make a simple measurement quickly and easily.Operating over a frequency range of 1 mHz to 250 kHz, the model 7265 offers full-scalevoltage sensitivities down to 2 nV and current sensitivities to 2 fA. The instrument has achoice of operating modes, signal recovery or vector voltmeter, for optimum measurement accuracy under different conditions, and the use of DSP techniques ensures exceptional performance.The instrument performs all of the normal measurements of a dual phase lock-in amplifier, measuring the in-phase and quadrature components, vector magnitude, phase angle and noise of the input signal.Several novel modes of operation are also include to give greater levels of versatility than ever before, for example:Virtual ReferenceUnder suitable conditions, this mode allows measurements to be made in the absence of a reference signalDual ReferenceIn this mode the instrument can make simultaneous measurements on two signals at different reference frequencies, which is ideal, for example, for use in source compensa
