5.6 Command Explanation
5-39 ZM2371/ZM2372
:CALCulate2:FORMat {Q|D|PHASe|X|B|RS|RP|G|LP|RDC|IMAGinary|REAL}
:CALCulate2:FORMat?
Description: Sets the secondary parameters to be measured.
Parameters: Q Quarity factor
（＝
1/D
）
D Dissipation factor (= tan  )
PHASe Phase angle of impedance (  , unit: degree)
X Reactance Xs expressed with series equivalent circuit
(unit:
 )
B Susceptance Bp expressed with parallel equivalent circuit
(unit: siemens)
RS Resistance Rs expressed with series equivalent circuit
(unit:
 )
RP Resistance Rp expressed with parallel equivalent circuit
(unit:
 )
G Conductance Gp expressed with parallel equivalent circuit
(unit: siemens)
LP Inductance Lp expressed with parallel equivalent circuit
(unit:
 )
RDC DC resistance (unit:  )
IMAGinary Imaginary part of immittance (X or B)
REAL
Real part of immittance (either Rs, Gp or Rdc)
Note: Immittance is generic name of impedance and
admittance.
Setting example: :CALC2:FORM D
Sets the secondary parameter to D.
Response: {Q|D|PHAS|X|B|RS|RP|G|LP|RDC|IMAG|REAL}
Query example: :CALC2:FORM?
Response example: D
The secondary parameter is dissipation factor D.
Remarks: Equivalent circuit assumed in the measurement of secondary
parameters is as follows:
PHASe, D, Q, RDC Not depend on the equivalent circuit.
X, RS Series equivalent circuit
G, B, LP, RP Parallel equivalent circuit
These parameters do not depend on [:SENSe]:FUNCtion[:ON]
command and equivalent circuit setting.
IMAGinary, REAL
These parameters depend on [:SENSe]:FUNCtion[:ON] command
and equivalent circuit setting.

See the following table
[:SENSe]:FUNCtion[:ON] IMAGinary REAL
FIMPedance (Series equivalent circuit) X Rs
（＝
ESR
）
FADMittance (Parallel equivalent circuit) B G
FIMPedance,FRESistance X Rdc
FADMittance,FRESistance B Rdc
The setting of equivalent circuit (series/parallel) and the setting of
automatic selection of equivalent circuit do not affect the secondary
parameter setting. However, the secondary parameters actually
measured and displayed may vary since [:SENSe]:FUNCtion[:ON]
command and equivalent circuit setting are interlocked.
