Introduction
Measurement Units
B1520A Multi Frequency CMU
This section describes typical specification of the multi frequency capacitance
measurement unit (CMU) for Agilent B1500A. The CMU performs the impedance
measurement and returns the specified measurement data such as Cp-G. Only one
module can be installed in one mainframe.
• Measurement parameters: See Table 2-13.
All measurement parameters are supported by Agilent B1500A in the GPIB
remote mode. H
owever, Agilent EasyEXPERT software supports the Cp-G,
Cp-D, Cs-Rs, and Z-θ measurements only.
• AC signal, output frequency:
1 kHz to 5 MHz
Setting resolution: 1 mHz (1 kHz to), 10 mHz (10 kHz to), 0.1 Hz (100 kHz to),
or 1 Hz
(1 MHz to 5 MHz)
• AC signal, output level:
10 mVrms to 250 mVrms, 1 mV resolution
•DC bias:
0 to ± 100 V
Setting resolution: 1 mV (0 to ± 25 V) or 5 mV (to ± 100 V)
DC bias > ± 25 V is available when using the SMU CMU unify unit (SCUU).
• Measurement range:
For the fixed ranging mode, measurement ran
ge (imp
edance range) must be
specified to perform measurement. Table 2-14 shows the available measurement
ranges and the corresponding impedance value. And Figure 2-6 shows the
calculation example of the imped
ance vs frequ
ency characteristics of a
capacitive load. Use these information to decide the measurement range.
Impedance Z is calcul
ated by the following formula.
Z = 1 / (2π f C)
where f is frequency (Hz) an
d C is capacitance (F).
