Setting The Fmin - Commtest Instruments vb Series Instrument Reference Manual

Setting the Fmin

The purpose of the Fmin setting is to eliminate the 'ski-slope' effect
from the low frequency end of the spectra. All spectral lines below
the Fmin value will be set to zero and will not be included in the
overall rms calculation.
Note: the value can only be entered in Hz, but will be displayed in
CPM in the Set Parameters Menu (if your Display Options are set to
CPM). So, for example, to obtain an Fmin of 60 CPM enter a value of
1 Hz - this is the default value.
