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
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
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.

High measurement accuracy
Capacitance, inductance and impedance basic accuracy are all an
excellent ±0.05%. Dissipation factor accuracy is ±0.0005 and the
quality factor accuracy is ±0.05%.
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.
Display formats available include series or parallel equivalent circuit.
An Equivalent Circuit Analysis function is available. 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 voltage.
The GPIB interface is used to control the instrument and read back
measured values for applications such as quality control or for archiving
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 PS/2 or USB interfaces, can be simply
connected to provide an alternative method of instrument control and
Data storage and retrieval
All measurement and setup data can be stored using the Ethernet
interface or a USB flash memory (supplied as standard).
Up to 20 instrument setups may be locally stored.
/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.
Hard copy printouts can be obtained in a number of ways including
direct to an HP-PCL compatible graphics printer or Epson compatible
text/ticket printer. A networked HP-PCL compatible printer may also be
used via the Ethernet connection.
Four front panel BNC connectors permit three or four terminal connections with the
screens at ground potential.
The 1J1011 Component Fixture,
supplied with all models, ensures optimum performance when measuring
a wide range of leaded components and devices.
Component Fixture, supplied with all models, ensures optimum
performance when measuring a wide range of leaded components and
Protection against charged capacitors
precision measuring instruments can be damaged by charged capacitors
which can cause costly repairs and unacceptable downtime. All the
models in the range incorporate protection against charged
