3.2 Swept SA Measurement
Image rejection requires two measurements, one with low-side mixing and the other
with high-side mixing. Internally, it uses two power-versus-frequency arrays to
produce a single, correct power-versus-frequency display.
This single result is created as the minimum of the two measurement arrays using
the minimum value at each index point (that is, frequency bin). Any response that
appears in both arrays is correct and is retained. Because both show the same value
(or nearly so), keeping the minimum provides a correct result. Any response that
appears in only one of the arrays is false and can be rejected. In this case, taking the
minimum provides a correct result because it ignores the larger false response.
Abort (Remote Command Only)
Stops the current measurement. Aborts the current measurement as quickly as
possible, resets the sweep and trigger systems, and puts the measurement into an
"idle" state. If the instrument is in the process of aligning when :ABORt is sent, the
alignment finishes before the abort function is performed, so :ABORt does not abort
an alignment.
