where y is the sensor output, x is the voltage output of the sensor, b is the Y-axis
intercept (offset), and m is the calibration multiplier, which is the slope of the line
representing the sensor’s response.
Outputs
The Outputs window allows you to configure the analog output channels, RS-232,
Ethernet, or Synchronous Device for Measurement (SDM) outputs.
The Setup tab presents Delay Time and Bandwidth settings that affect all outputs
(RS-232, Ethernet, DACs, and SDM). Bandwidth (5, 10 or 20 Hz) determines the
signal averaging done by the digital filter. To avoid aliasing (only a concern for co-
spectra, not for fluxes), one should sample the gas anlyzer at a frequency greater
than or equal to 2 times the bandwidth. Thus, if you are sampling at 10 Hz, the
bandwidth is 5 Hz.
