Low spur mode
Low spur mode is provided for applications requiring optimum signal purity. In low
spur mode the core frequency synthesiser is operated in integer mode instead of the
normal fractional mode thus avoiding the possibility of fractional spurs. Notably,
integer boundary spurs are eliminated, which in fractional synthesiser mode can
occur up to a few kHz away from the output carrier, depending on frequency setting.
In Low Spur mode the frequency resolution is limited to 1MHz.
To activate low spur mode, firstly open the utility menu by pressing UTILITY and
select
Instrument
.
Select the
Low Spur Mode
parameter window. Select
On
and touch
OK
. Low spur
mode is now on, this will be shown in the information window on the home screen.
