lock-in amplifier uncertainty

[Nan Yang]

Hi,

I am using a NI labview lock-in amplifier, "Multichenel locl in-DAQmx", to read AC signals from 50Hz to 500Hz. Now I want to know how acurate the phase and amplitude are, or to say the uncertainty of the lock-in amplifier. My card is NI PCI-6035E and I am using labview8.2. The lock-in amplifier is download from Download the FREE NI LabVIEW Lock-In Amplifier Start-Up Kit last year.

thank you,

Nan

Hi Nan,

As the lock-in amplifier toolkit is purely software, the only inaccuracies you need to worry about are those of the board being used in conjunction with the lock-in amplifier. The specifications for your PCI-6035E can be found in the NI 6034E/6035E/6036E Family Specifications manual.

Please post back if you have further questions.
