STANFORD RESEARCH SR830 - $3,495.00 Educator's Special Price -- Our Most Popular Lock-In Amplifier ! The Stanford Research SR810 Lock-In Amplifier and SR830 Lock-In Amplifier provide high performance at a reasonable cost. The SR830 simultaneously displays the magnitude and phase of a signal, while the SR810 displays magnitude only. Both instruments use digital signal processing (DSP) to replace the demodulators, output filters, and amplifiers found in conventional lock-ins. The SR810 and SR830 provide uncompromised performance with an operating range of 1 mHz to 102 kHz and 100 dB of drift-free dynamic reserve. IEEE-488 and RS232 interfaces are standard.
