Part II: Settings and Measurements
A Note on Upstream Spectrum Analysis
The DS2831’s downstream & upstream spectrum analysis functions are almost the same, with a few
exceptions. First, for quick ease of use, US spectrum analysis SPAN presets offer several fixed modes: 4-46
MHz, 4-68 MHz, 4-88 MHz, 4-120 MHz and 4-210MHz, however, you can tune any specific SPAN setting either
with START/STOP or Center Freq/Span, max span is 206MHz. Although the RBW is fixed at 300KHz in this
mode, the sweep and trace settings are flexible to enhance the ability to troubleshoot US events.
