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).
