– When
Frequency Converter
is selected, the VSA is set by default to the
specified
IF Center Frequency
. The trace data annotated measurement
“Center” frequency is the specified
RF Center Frequency
. This reflects the fact
that the external downconverter is tuned to the
RF Center Frequency
and
produces an output at the
IF Center Frequency
. Select
Inverted Spectrum
if
the downconverter outputs a spectrum that is mirrored relative to the input.
– The measurement center frequency can be changed within the limitations of
the measurement hardware as well as the
IF Band wid th
specified on the
User
Correction
tab. When the measurement center frequency and span are
changed, the measurement hardware is tuned within the IF range of the
external downconverter. The displayed center frequency is changed
appropriately, even though the
RF Center Frequency
is unchanged. This
reflects the fact that a different portion of the bandwidth made available by the
external converter is being looked at.
– The measurement center frequency is limited to the
RF Center Frequency
± ½
the
IF Band wid th
, unless the measurement hardware limits are more
restrictive. Spectrum displays are blanked outside the same limits.
