Spectrum Tool Features
Feature
Function
Frequency (X-Axis)
Center Frequency (MHz)
The frequency in the center of the display.
Span (MHz)
The range of frequencies in the display.
Start Frequency (MHz)
The frequency at the left end of the display.
Stop Frequency (MHz)
The frequency at the right end of the display.
Resolution Bandwidth (MHz)
The frequency range represented by each point on the spectral display.
Amplitude (Y-Axis)
Maximum (dBmV)
Enter a maximum power level in dBmV to control the scale of the Y-axis on the display.
Minimum (dBmV)
Enter a minimum power level in dBmV to control the scale of the Y-axis on the display.
Measurements
Peak (dBmV)
The highest power level shown on the display. The reported value is dependant upon
the Resolution Bandwidth.
Peak Position (MHz)
The approximate frequency with the highest power level on the display.
Horizontal Markers
Show Markers

H2 Power (dBmV)
Enter a power level in dBmV
▲Power (dBmV)
The difference in power between the two markers.
Vertical Markers
Show Markers
Show markers for V1 and/or V2
V1 Frequency (MHz)
Enter a frequency level in MHz
