Press the Sweep Interval submenu key and use the rotary knob or keypad to set the time from 0 seconds to 60 seconds.
To set the total time span for a display, press the Time Span submenu key and use the rotary knob or keypad to enter a time between 1 minute and 4320 minutes (72 hours). When the time span is reached, the measurement stops. When set to zero (Auto) time span, the measurement runs continuously. Entering a time span value causes the corresponding sweep interval value to be automatically computed and shown when the Sweep Interval submenu key is pressed.
When the Time Span is set to an interval other than Auto, the spectrogram plots will be automatically saved when the waterfall display is full by pressing the Record submenu key.
The Time Cursor is used to view the spectrum at any spot in the spectrogram display. Press the Time Cursor submenu key to turn on the horizontal time cursor. Use the Up/Down arrow key to move the cursor vertically through the spectrogram. The date and time that the measurement at the cursor position was taken is displayed at the top of the screen.
