Selecting measurement parameters
To select the measurement parameters, use the following commands.
•
:CALC1:FORM
on page 147
•
:CALC2:FORM
on page 150
You can select one of the following measurement parameter combinations shown in Table
3-1. If you select one parameter using the GPIB 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)
G: Equivalent parallel conductance measured using the parallel
equivalent circuit model
Rp: Equivalent parallel resistance measured using the parallel equivalent
circuit model
Rs: Equivalent series resistance measured using the series equivalent
circuit model
Setting up measurement signal (frequency and level)
Setting up frequency
To select the measurement signal frequency (1 kHz/1 MHz), use the following command.
•
:SOUR:FREQ
on page 187
Setting up level
To set the measurement signal level, use the following command.
• :SOUR:VOLT on page 188
