  Silicon microstrip detectors are widely used in experiments for space
astronomy. Before the detector is assembled, extensive characterization of the
silicon microstrip sensors is indispensable and challenging. This work
electrically evaluates a series of sensor parameters, including the depletion
voltage, bias resistance, metal strip resistance, total leakage current, strip
leakage current, coupling capacitance, and interstrip capacitance. Two methods
are used to accurately measure the strip leakage current, and the test results
match each other well. In measuring the coupling capacitance, we extract the
correct value based on a SPICE model and two-port network analysis. In
addition, the expression of the measured bias resistance is deduced based on
the SPICE model.
