Start Freq
Sets the start frequency of the current frequency channel. Press this key or touch the
specified menu item on the screen to set the frequency entry mode to Start
Frequency/Stop Frequency. The start frequency and stop frequency values are
respectively displayed at the lower left and right side of the graticule.
Remarks:
⚫ When you modify the start frequency, the span and center frequency will be
changed. The changes of span will affect other system parameters. For details,
please refer to "Span".
⚫ In zero span mode, the values of start frequency, stop frequency, and center
frequency are the same, so once one of the parameter values is modified, the
other two values will be modified automatically.
⚫ You can use the numeric keys, the knob, and the arrow keys on the front panel
to modify this parameter; also you can modify it on the touchscreen. For details,
refer to descriptions in "Parameter Setting".
