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 "Bandwidth" on page 42.
Remote command:
CHANnel<m>:BANDwidth on page 302
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 on page 353
Sample Frequency
Indicates the sample rate with which FFT analysis is performed. This value may differ
from the Sampling Rate C1 - C4 in the data acquisition settings, as the number of sam-
ples must be adjusted to a value of 2
x
FFT points.
