3 Setting Up Measurement Conditions and Display
This chapter describes how to set up the measurement conditions and display.
It also describes how to save/recall the instrument settings including the
measurement conditions.
Setting Up Measurement Conditions
Selecting measurement parameters
To select the measurement parameters, use the following commands.
• :CALCulate1:FORMat on page 188
• :CALCulate2:FORMat on page 191
You can select one of the following measurement parameter combinations
shown in Table 3-1. If you select one parameter using the SCPI command and
the resulting parameter combination is not among those in Table 3-1, the
other parameter is automatically changed to a proper parameter. For example,
when the primary parameter is Cp and you select Rs as the secondary
parameter, the primary parameter is automatically changed to Cs.
Each parameter is described below.
Cp: Capacitance value measured using the parallel equivalent
circuit model
Cs: Capacitance value measured using the series equivalent
circuit model
D: Dissipation factor
Q: Quality factor (inverse of D)
