Signal Recovery returns with two updated and improved General Purpose DSP Lock-in Amplifiers and more.
The 7230A General Purpose DSP Lock-in Amplifier offers dual reference & harmonic detection and a low profile design for integration with larger systems.
The 7270 General Purpose DSP Lock-in Amplifier (shown above) features computer control via Ethernet and USB, in addition to front-panel control.
The 5402A Low Noise Current Amplifier is designed for use whenever the signal source is a current source - for example, an electron multiplier, ion collector, photo multiplier, or photodiode, or when using a lock-in amplifier to measure sample impedance.
The 5113A Low Noise Voltage Preamplifier is a high performance, low noise voltage preamplifier with continuously adjustable gain and selectable high, low and bandpass filtering.
