The Wayne Kerr 6550B Benchtop Precision Impedance Analyzer provides precise and fast testing of devices at frequencies up to 50 MHz. Basic measurement accuracy is ±0.05%, making the instrument the best in its class.

The accuracy and versatility makes this precision instrument the ideal choice for many different tasks and applications, including passive component design, dielectric material testing and resonant frequency characterization.

AC Measurement Parameters:

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 6550B Benchtop Precision Impedance Analyzer is 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 color display. Swept parameters are frequency, drive level and DC bias (option, not included).

Display formats available include series or parallel equivalent circuit. Polar and Complex plots can also be displayed when the /Y firmware option (not included) is installed.

An Equivalent Circuit Analysis function is available as the /E firmware option (not included). This allows modelling and curve fitting to various models of equivalent circuits. Four 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.

A meter mode is available for single frequency measurements.

Variable Drive and Bias Levels

AC drive levels up to 1V or 20 mA can be selected to evaluate components in realistic operating environments. The /D1 DC bias option (not included) provides 0 to +40V dc bias voltage and 0 to +100mA DC bias current. The /D2 option (not included) 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 (both not included) 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 (both not included) 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.

Data Storage and Retrieval

All measurement and setup data can be stored using the Ethernet interface or a USB memory drive.

Setup Data

Up to 20 instrument setups may be locally stored for each mode. Additional setups can be stored to the USB memory stick that is supplied with each unit as standard.

Bin Handling Option (not included)

The /B1 option (non-isolated 5V) or /B2 option (isolated 24V) signals are available through a 25-way D-type connector (options not included). 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.

The optional 1J1012 (2-terminal), 1J1014 (4-terminal) and 1J1024 (2-terminal small body DUT) SMD Fixtures (all sold separately) allow connection to surface mount devices.

Protection Against Charged Capacitors

High precision measuring instruments can be damaged. The 6550B Benchtop Precision Impedance Analyzer incorporates protection against charged capacitors.
