RF:SPAN <NR3>
RF:SPAN?
Related Commands
RF:FREQuency, RF:STARt, RF:STOP
Arguments
<NR3> is a floating point number.
Examples
RF:SPAN 2E9 sets the span to 2 GHz.
RF:SPAN? might return 10.0000E+6, indicating the span is 10MHz.
RF:SPANRbwratio
This command specifies the ratio of the span to the resolution bandwidth (RBW)
that will be used when the RBW Mode is set to AUTO. (In order to set the RBW
Mode to AUTO, use the command RF:RBW:MODe.)
The span is the width of the frequency domain trace in Hz, which is equal to the
stop frequency minus the start frequency. The RBW is the width of the narrowest
measurable band of frequencies in a frequency domain trace. The default RBW
ratio is a factor of 1000.
Conditions
MDO3000, MDO4000/B, or MDO4000C models with option SA3 or SA6 only.
Group
RF
Syntax
RF:SPANRbwratio <NR3>
RF
:SPANRbwratio?
Arguments
<NR3> is a floating point number.
Examples
RF:SPANRbwratio 1000 would force the scope to adjust the RBW to one
one-thousandth of the span.
RF:SPANRbwratio? might return 1.0000E+3, which means the RBW has been
set to one one-thousandth of the span.
