Peak Hold –
Has two options “
on
” and “
off
”. However, it
is only operational when the “continuous sweep” option is
selected. As the sweeps continue this allows the present
sweep readings to be compared against the previous
readings which then determines the highest level reached.
(Phase / Gain) Graph Scaling –
Has two options, “
auto”
and
“manual”,
in most cases auto-scaling will work and
adjusts the graph scale automatically to suit the
measurement levels.
When a more specific graph scale is needed then the
“
manual
” option may be selected. This adds two functions
to the left menu,
“graph maximum”
and
“graph minimum”
,
here both levels can be specifically set
Frequency Marker–
Has three options
“off”, “single” and
“dual”.
If “single” is selected this adds “marker 1” function
to the left menu and If “dual” is selected this also adds
“marker 2” function to the left menu, allowing the setting
of a specific frequency to be entered. While in the sweep
mode it draws a vertical line on the graph at that
frequency
allowing
the
user
to
determine
the
measurement at that desired frequency.
Search for Peak–
Has two options
“on”
and
“off”.
However, in LCR mode it has three options, “Off”, “Single”,
and “Dual”
.
If “on” is selected, this draws a vertical line at
the frequency of peak measurement, or the option of one
or two frequency peaks in LCR mode.
At the end of a sweep, the generator may be set to be on
or off. The settings used are those in the normal generator
menu.
