EMI Filter
Description The built-in EMI filter is used for specific
measurement situations such as EMI average
detection, where a higher level of sensitivity is
required than the standard configuration.
When turned on, the RBW is set to -6dB,
indicated by an asterisk (*).
When any measurement functions are turned
on (see page 111 for details), the EMI filter is
automatically disabled. Conversely if the EMI
filter is turned on, any measurement functions
are turned off.
Operation 1. Press
BW/Avg
> EMI Filter[F6] and toggle EMI
filter on or off.
Sweep
The GSP-930 has a number of sweep options including setting the
sweep time and sweep mode(continuous, single). The GSP-930 also
has gated sweep modes.
Sweep Time
Description Sweep time defines the length of time the
system takes to "sweep” the current frequency
span. Note, however, that sweep time and
RBW/VBW are in a trade-off. Faster sweep
times update the display more frequently but
make RBW and VBW wider, reducing the
capability to separate signals at close
frequencies.
