A utomatic Recall of Instrument Settings
A utomatic Recall of Instrument Settings
The receiver remembers most measurement settings when you switch back and forth between
channels , domains , parameters , or display formats . (This feature remembers all measurement
settings except stimulus settings .) This feature is automatic , and does not require you to use the
Save or Recall functions . The feature is called \limited instrument state memory ."
Limited instrument state memory works by assigning a hierarchy to the instrument settings .
Here is the hierarchy:
Channel (1 or 2)
Domain (Frequency , Angle , or Time)
P arameter (1, 2, 3, or 4)
F ormat (any display format)
Response (scale and reference line)
Every mode in the above list remembers all settings you make that are lower in the hierarchy.
F or example , assume you choose the following measurement settings .
Channel 1
Angle Domain
P arameter 3
Log mag (format)
Reference -10 dB
Scale 5 dB/div
Now you go to Channel 2 and make completely dierent settings .
When you go back to Channel 1, the settings shown above will automatically resume . This
hierarchical memory applies to all the controls in the above list.
