Spectrum Analyzer Mode Key Descriptions
Spectrum Analyzer Mode Functions
sets a lower boundary to the active trace. The threshold line “clips” signals that appear below the line when this function is on. The boundary is defined in amplitude units that correspond to its vertical position when compared to the reference level.
The value of the threshold appears in the active-function block and on the lower-left side of the screen. The threshold level does not influence the trace memory or marker position. The peaks found by the markers must be at
least the peak-excursion value above the threshold level. The value of the threshold level can be changed using the step keys, the knob, or the numeric keypad. Pressing any digit, 0 through 9, on the numeric keypad brings up the selected terminator menu. If a threshold is active, press THl?.ESHL.D ON OFF until OFF is selected to turn the threshold display off. The threshold value affects peak searching even when the THRESHLD function is set to off.
Front-Panel Key Access (jjlsp
accesses the softkey menu used to set and display the real-time clock.
