ETS-Lindgren FM5004 Field Monitor (Archived) - Manual (Page 45)

FILTER SIZE
Calls up the numeric entry screen to select the number of samples to use for
each analog output update. The saved sample represents a sliding window and
serves as a smoothing function for the analog output signal. The analog output
level is updated every sample according to the samples per second setting in the
Main Menu.
• If the filter size is greater than one, the sample window contains the
current sample plus the most recent samples.
• If the filter size is set to one, only the current sample is used by the
analog output system.
The minimum/maximum/average setting affects how the data is processed. See
Min/Max/Avg on page 44.
LOG SCALE OUTPUT
Selects either linear or log scale for the analog output voltage.
• When selected, the output will track a logarithmic curve with a zero
field level being zero volts out and a full scale field level being five volts
out.
• When deselected, the endpoints will be the same but the analog
voltage out to field level ratio will be linear.
