Reducing Recall Time
‘lb reduce time during recall and frequency changes, the raw offset function and the
spur avoidance function can be turned off. turn these functions off, press
:
,
The raw offset function is normally on and controls the sampler and attenuator offsets. The
spur avoidance function is normally on and generates values as part of the sampler offset table.
The creation of this table takes considerable time during a recall of an instrument state.
lb save time at recalls and during frequency changes, both functions should be turned off. This
will avoid generating the sampler offset table.
Raw offsets may be turned on or off individually for each channel. They follow the channel
coupling. For dual channel operation, raw offsets should be turned off for each channel if the
channels are uncoupled. Spur avoidance is always coupled between channels, therefore both
channels are turned on or off at the same time.
Both functions must be turned off to realize the recall time savings.
The following table lists the recall state times with the following functions on or raw
offsets, spur avoidance, and blank display. Using blank display may speed up recall times.
