Lock-in Amplifier

The Texas A&M University System is seeking bids for the purchase of lock-in amplifiers for the Department of Mechanical Engineering at Texas A&M University. The bid specifications include requirements for two demodulation channels, frequency generator outputs, phase resolution, dual phase demodulation, and software interface compatibility. The bid must include a company quote with sufficient details to demonstrate that the offered items meet all specifications. The award will be based on the best value to the A&M System, considering factors such as pricing, shipping terms, and delivery time-frame. • The lock-in amplifiers must have two demodulation channels capable of demodulating signals up to 600 MHz. • The lock-in amplifiers must have two frequency generator outputs from DC-600 MHz. • The lock-in amplifiers must have a phase resolution of 1 μdeg for high frequencies > 100 MHz. • The lock-in amplifiers must have dual phase demodulation and DAQ capabilities for all channels. • The lock-in amplifiers must have a software interface compatible with Python APIs. • The lock-in amplifiers must have ultralow signal input noise preferably around 4 nV/√Hz at frequencies higher than 5 MHz. • The lock-in amplifiers must have an in-built frequency response analyzer, plotter, and digital oscilloscope. • The lock-in amplifiers must be capable of enhancements to demodulate mixed signals upon field upgrade.
