EQUC
Syntax EQUC {CIRA|CIRB|CIRC|CIRD|CIRE}
EQUC?
Description Selects an equivalent circuit model (A to E) used when executing the equivalent circuit
analysis with the “CALECPARA” command on page 275. For details on each equivalent
circuit model, refer to “Equivalent circuit analysis” on page 100.

EQUC0?
Syntax EQUC0? <numeric 1>[HZ|MHZ]
Description If the sweep parameter is frequency, within the waveform analysis range specified with the
“ANARANG” command on page 267, reads out equivalent circuit parameter C0 (parallel
capacitance) at the specified frequency. If the sweep parameter is not frequency, executing
this command causes an error and 0 is always read out.(Query only)
Parameters
Query response
{numeric 2}<newline><^END>
Note that, if the specified frequency is out of the analysis range, 0 is read out.
Corresponding
key No front panel key is available to execute this function.
Description
CIRA (initial value) Specifies equivalent circuit model A.
CIRB Specifies equivalent circuit model B.
CIRC Specifies equivalent circuit model C.
CIRD Specifies equivalent circuit model D.
CIRE Specifies equivalent circuit model E.
