The parameter on the display depends on the selected component:
parameter display null meter
in-phase in-phase
quadrature quadrature
tan  tan  tan 
magnitude magnitude magnitude
phase phase
rms rms rms2
rms2/1 rms2/rms1 rms2/rms1
in-phase ratio in-phase ratio in-phase ratio
LVDT diff LVDT LVDT
LVDT ratio LVDT LVDT
The null meter may be manually ranged or will automatically range as the signal
varies. When manually ranging, ZOOM+ and ZOOM- adjust the range by a
decade.
There is a phase offset option that applies a vector rotation of a user selectable
phase shift to the CH2 input data.
The PSM3750 can operate either in real time mode at a single frequency where
the measurements are filtered and updated on the display; or it can sweep a
range of frequencies and present the results as a table or graphs. Before
performing a sweep, the desired parameter must be selected.
The frequency points to be measured are specified with three parameters:
number of steps
start frequency
end frequency
