Band Adjust
Adjusts the bandwidth parameters for the band function.
1. Band Span
Sets the bandwidth of the signal involved in the calculation for the band
function.
2. Band Left
Sets the left edge frequency of the signal involved in the calculation for the band
function.
3. Band Right
Sets the right edge frequency of the signal involved in the calculation for the
band function.
4. Band Span Auto
Sets the manual/auto setting of the band span. When it is set to "Auto", the
band span is 5% of the span or 5% of the sweep time. When you select
"Manual", you can press Band Span to set it.
Marker Counter
Enables or disables the frequency counter function of the current marker.
Remarks:
 If no active marker currently exists, turning on the frequency counter will open a
Position marker automatically.
 The frequency readout will be more accurate when the frequency counter is
enabled.
 In zero span mode, enabling the frequency counter can measure the frequency
near the center frequency.
 In the Delta marker mode, if the current reference marker is not a fixed type,
then the reference marker can also be used for frequency counting.
Gate Time
Sets the length of time for the marker counter to make gate measurement.
