Wayne Kerr 6520B/E Equivalent Circuit Analysis Option for the 6520B 20Hz - 20MHz Precision Impedance Analyzer.

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 characterization.

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.

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.

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.

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 operation.

Data storage and retrieval: All measurement and setup data can be stored using the Ethernet interface or a USB flash memory (supplied as standard).

Setup Data: Up to 20 instrument setups may be locally stored.

Bin handling: /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 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.

Component connections: 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.
