Engineers need to evaluate component characteristics at
high frequencies with very high levels of accuracy. The
65120B 120MHz Precision Impedance Analyzer is therefore
ideal for many demanding tasks, combining accuracy and
ease of use at an affordable price. If a maximum frequency
less than 120MHz is required, other models are available in
this range.

The 6500B series of Precision Impedance Analyzers provide
precise and fast testing of devices at frequencies up to 120
MHz. Basic measurement accuracy is ±0.05% making the
instruments the best in their class.
The accuracy and versatility makes these precision instruments
the ideal choice for many different tasks and applications
including passive component design, dielectric material
testing and resonant frequency characterisation.

Graphical sweep of components
The 6500B series of Precision Impedance Analyzers are highly
accurate high frequency component analyzers with a host of
useful features.
Graphical sweep of two measured parameters is available and
displayed on the large clear colour display. Swept parameters
are frequency, drive level and DC bias (option).
Display formats available include series or parallel equivalent
circuit. Polar and Complex plots can also be displayed when
the /Y firmware option is installed.
An Equivalent Circuit Analysis function is available as the /E
firmware option. This allows modelling and curve fitting to
various models of equivalent circuits. 4 types of 3-component
model and 1 type of 4-component model can be selected. The
instrument will calculate the nearest equivalent circuit
parameters for the measurement traces and revise the results
for the different models instantly. Alternatively the parameters
can be entered by the user and the instrument will plot the
resulting frequency characteristics and revise the plot
between the various models instantly.
For single frequency measurements a meter mode is available.
Variable drive and bias levels
AC drive levels up to 1V or 20 mA can be selected to evaluate
components in realistic operating environments. /D1 DC bias
option provides 0 to +40V dc bias voltage and 0 to +100mA
dc bias current. /D2 option provides -40V to +40V dc bias
External control
The GPIB interface is used to control the instrument and read
back measured values for applications such as quality control
or for archiving purposes.
All measurement and setup data can be stored using the
Ethernet interface or a USB memory (supplied as standard).
Setup Data
Up to 20 instrument setups may be locally stored for each
mode. Additional setups can be stored to the USB memory
stick which is supplied with each unit as standard.
Bin handling option
/B1 option (non-isolated 5V) or /B2 option (isolated 24V)
signals are available through a 25-way D-type connector. 10
bins can be set using absolute or percentage limits.
Printer outputs
Hard copy printouts can be obtained using an HP-PCL
compatible graphics printer. A networked HP-PCL compatible
printer may also be used via the Ethernet connection.
Component connections
Four front panel BNC connectors permit three or four terminal
connections with the screens at ground potential.
The 1J1011 Component Fixture, supplied as standard, ensures
optimum performance when measuring a wide range of
leaded components and devices.
1J1012 (2-terminal), 1J1014 (4-terminal) and 1J1024 (2terminal small body DUT) SMD Fixtures allow connection to
surface mount devices.
Protection against charged capacitors
High precision measuring instruments can be damaged by All
the models in the range incorporate protection against
charged capacitors.
An Ethernet interface similarly allows the instrument to be
controlled and to send out data, allowing it to be integrated
into many test environments.
Wide range of interfaces
An external monitor or projector may be connected to the
instrument’s VGA output. The ability to provide a large screen
display of measurement results is invaluable in production
environments or for teaching and training.
Instrument control from both a keyboard and mouse is
available. Any keyboard or mouse, with either a PS/2 or USB
interface, can simply be connected to provide an alternative
method of instrument control and operation.
