Product technial information：

For signals with source impedance >100 Ω, it is important to maintain a balanced source 

impedance, which means that both terminals of the source have equal impedance to the signal 

source ground. Providing a balanced source impedance is critical to achieving optimal noise 

rejection, since any noise pickup will induce a noise voltage common to both conductors, which 

can then be rejected by the analog input Programmable Gain Instrumentation Amplifier (PGIA). 

Noise pickup in a system with an unbalanced source impedance will induce noise voltages of 

different amplitudes on each conductor, which appears as a differential voltage that will be 

measured as a signal voltage. Additionally, if the isolation voltage (VISO) is a time varying 

voltage or noisy DC source, a balanced source impedance is critical in ensuring that VISO is 

common to both inputs, which maximizes the ability of the PGIA to reject VISO. A mismatch in 

the source impedance can cause a portion of VISO to appear as a differential voltage between AI+ 

and AI-.
