Reducing Recall Time
To reduce time during recall, turn off the raw offset function by pressing:
The raw offset function is normally on and controls the sampler and attenuator offsets. The
creation of the sampler offset table takes considerable time during a recall of an instrument
state. save time at recalls, this function should be turned off.
Raw offsets may be turned on or off individually for each channel. They follow the channel
coupling. Therefore, for dual channel operation, raw offsets should be turned off for each
channel.
The following table lists the recall state times with the raw offsets function on or off.

Sampler
correction:
This smoothes the raw frequency response of the receiver hardware. Sampler
correction is not required if a calibration measurement is to be done. sure
to turn off sampler correction before performing the calibration.
Attenuator
offsets:
These offsets compensate for the effects of the step attenuator in the source
path. For example, with the offsets ON, you can change the attenuator while
viewing a parameter (such as and the trace will stay on the
screen. With offsets OFF, it will move with each attenuator step. Attenuator
offsets are turned off primarily for special use of pre-raw data.
