Source Sought Notice for Lock-In Amplifier

The National Institute of Standards and Technology (NIST) is conducting market research to identify potential sources of commercial products/services that satisfy the government's anticipated needs for a lock-in amplifier and arbitrary waveform generator. The lock-in amplifier should be able to analyze signals up to 600 MHz, have at least two channels, demodulate at least 8 harmonic signals, and have a 50 Ohm input impedance. The arbitrary waveform generator should have at least 2.4 GSa/s, at least four channels, and at least 250 MHz bandwidth. * The lock-in amplifier and arbitrary waveform generator will be used to create signals for a laser doppler vibrometer measurement setup. * The devices will produce signals and demodulate them to measure the electrical response associated with surface vibrations in acoustic filter devices. * The working principle of the lock-in amplifier relies on demodulation or phase-sensitive detection. * The arbitrary waveform generator produces electrical signals of arbitrary shape. * The complexity of the signal is defined by the number of samples per second the devices can produce.
