Concept of Command
 Subsystem Command Tree
The top of the subsystem command tree is called the root command, or simply
the root. To reach the low-level commands, you must specify a particular path.
After Power ON or after *RST, the current path is set to the root. The path
settings are change as follows:
Colon (:)
When a colon is placed between two command mnemonics, the
colon moves the current path down on level on the command
tree. When the colon is the first character of a command, it
specifies that the following command mnemonics a root-level
command.
Semicolon (;) A semicolon separates two commands in the same message
without changing the current path.
Proper use of the Colon and Semicolon as follows:
It shows how character input time can be saved by properly using semicolons.
Sending the message
:AA:BB:EE;FF;GG
is equivalent to sending the following three messages.
:AA:BB:EE
:AA:BB:FF
:AA:BB:GG

3. Parameter
4.Program Message Terminator
Parameter:
There must be a <space> between the last command and the first parameter in a
subsystem command.
For example:
:MEASure:PARAmeter Z
If you send more than one parameter with a single command, each parameter must be
separated by a comma.
For example:
:MEASure:PARAmeter Z,LS,Q
<> Angular brackets enclose words or characters that are used to symbolize a
program code parameter or a command.
<NR1>Integers
<NR2> Decimal number

Example: 1,2,3,4
Example: 0.1,0.23,0.001
Example: 2.2E+2,1.1E-1
Example: ON,OFF,MAXimum,MINimum
When several items are enclosed by braces, one and only one of these elements
may be selected. A vertical bar can be read as "or" and is used to separate
alternative parameter options.
For example:
Means
:MEASure:SPEEd{MAXimum|FAST|MEDium|SLOW|SLOW2}
:MEASure:SPEEd MAXimum or :MEASure:SPEEd FAST……。

 Resistance (R) and Conductance (G)
The resistance is a measure of the difficulty to pass an electric current through
that conductor. The SI unit of resistance is the “ohm” (Ω). The inverse quantity is
electrical conductance, and this is the ease with which an electric current
passes through a circuit. The SI unit of conductance is measured in Siemens (S)
and it the reciprocal of the resistance (G=1/R).

 Inductance (L)
Inductance is the property of an electrical conductor by which a change in
current through it induces an electromotive force (EMF) in both the
conductor itself and in any nearby conductors by mutual inductance. In the
SI system, the measurement unit for inductance is the Henry (with the unit
symbol H).

 Reactance (X) and Susceptance (B)
In AC circuit analysis, reactance is represented by the capital letter “X”
which is the imaginary a part of complex impedance. Reactance is the
opposition of a circuit element to a change in the current or voltage, due to
that element's inductance or capacitance which is similar to the opposition
of resistance to current in a DC circuit. In an AC circuit (e.g. a series RLC
circuit) inductance and capacitance may oppose current and are named
reactance measured in units of Ohm (Ω).
In electrical engineering, susceptance (B) is the imaginary part of
admittance. The inverse of admittance is impedance, and the real part of
admittance is conductance. The latter is the reciprocal of impedance (B=1/X)
and is measured in units of Siemens (S).

 Quality factor (Q) and Dissipation factor (D)
The quality factor measures energies consumed by relative frequency. In
general, the better a circuit's quality factor the better its selectivity.
The dissipation factor is the reciprocal of quality factor. It is the signal angle
loss by a capacitor (or inductor) and acting frequency at a fixed temperature.
Phase shifts caused by time lag between an externally applied voltage and
current generated may result in loss of current and energy dissipation. Here
the total current (I) is the sum of the charging current (Ic) by a 90 ﾟ voltage
phase shift and loss current (IR) of the same voltage. The loss angle is the
angle δ between the total current and charging current and tanδ the
dissipation factor (symbol: D) as shown in the figure below:

 Overall Impedance Measurement Theory
The simplified model of the 6632 impedance measurement, Vs is the test signal
voltage and RO is source resistance. If the current across the DUT is I when a
test signal voltage V is applied, the DUT's impedance, Z, is expressed by Z = .
Impedance, Z, contains real and imaginary parts. The figure shows vector
representation of impedance as follow.
R: Resistance
X: Reactance
|Z|: Impedance
θ: Phase Angle
97
Impedance, Z, can also be expressed as admittance, Y. Admittance is
expressed in terms of impedance, Z, by Y = .
Y=
OR
Y=)
For parallel connected circuits, it is better to use admittance, Y.
G : Conductance
B : Susceptance
|Y|: Admittance
98
The 6632 measures a DUT's impedance, Z, which is a vector value, and gives
the result using the following equivalent circuits.
Lp : Parallel Inductance
Ls : Series Inductance
Q : Quality factor
Cp : Parallel Capacitance
Cs : Series Capacitance
D : Dissipation factor

 High and low impedance criteria
The following criteria can be used to roughly discriminate between low, middle,
and highimpedances by following figure. The medium Z range may be covered
with an extension ofeither the low Z or high Z range. These criteria differ
somewhat, depending on the frequencyand component type.
In the frequency region where the primary capacitance or inductance of a
component exhibitsalmost a flat frequency response, either a series or parallel
equivalent circuit can be applied as asuitable model to express the real
impedance characteristic. Practically, the simplest series and parallelmodels are
effective in most cases when representing characteristics of general
capacitor,inductor, and resistor components.
