Channel Bandwidth
Determines the frequency limit of the spectrum. Frequencies above the selected limit
are removed to reduce noise at different levels. Values from 1
kHz to 10
MHz can be
selected. Alternatively, the full span of the current input signal can be selected.
For more details on the channel bandwidth, see
Remote command:
X-Scaling
Defines the scaling method for the frequency (x-)axis of the spectrum display.
"Linear"
Linear scaling
"Logarithmic"
Logarithmic scaling
Note that in this mode, not all possible amplitude values for a specific
frequency may occur. Each result is indicated by a bright, colored
trace point.
The DC amplitude (at 0
Hz) is not displayed, as lg(0) is not defined.
Remote command:
SPECtrum:FREQuency:HORizontal:SCALe
Sample Frequency
Indicates the sample rate with which FFT analysis is performed. This value may differ
from the
in the data acquisition settings, as the number of sam-
ples must be adjusted to a value of 2
x
FFT points.
