Miscellaneous
This chapter describes some miscellaneous operations related to searching
channels, settings files, and Janitor program.
11.1 Searching channels
The program offers several search routines to search channels for some
particular feature.
Following searches can be performed from the
Search
menu:
Worst offset Find channel whose curve crosses zero line at a level
that differs most from the value defined for the current
working point.
Worst noise Find channel having largest white noise level.
Weird Phi0
Find channel whose flux quantum size differs most from
the other channels.
Next Find next worst channel. Before this command one of the
first three commands must be issued to select which
parameter should be searched.
11.2 Loading and saving in special cases
In addition to normal saving and loading of tuning parameters, there are
two options: loading of parameters of a single channel, and saving and
loading of some selected parameters only.
The normal File > Save tunings operation saves all parameters, except
the preference parameters. The normal File > Load tunings loads only
operating point parameters, all other parameters are neglected. Therefore
one can for example check from a tuning file, what kind of measurement
settings were used, when the file was made, but these measurement set-
tings do not affect the current settings when the file is loaded.
Using the command File > Save > Load current channel only one can
load only the operating point parameters of the current channel (channel
selected to be viewed).
To save or load only some selected parameters to all of the channels, use
menu commands
File > Load > Load selected params or File > Save >
Save selected params . These commands pop up a special file selection
dialog button which has a toggle button for each parameter group. By
selecting and deselecting these buttons, one can choose which parameter
groups are saved or loaded.
