Überblick

The 6500B series of Precision Impedance Analyzers provide precise and fast testing of components at frequencies up to 120 MHz. Basic measurement accuracy is ±0.05% making the instruments the best in the class.

The accuracy and versatility makes the precision analyzers the ideal choice for many different tasks and applications including passive component design, dielectric material characterisation and manufacturing test.

Engineers need to evaluate component characteristics at high frequencies with high levels of accuracy. The 65120B 120 MHz Precision Impedance Analyzer is therefore ideal for many demanding tasks, combining accuracy and ease of use at an affordable price. If a frequency range up to 120 MHz is not required then other models are available. The 6505B 5MHz instrument is the entry level model in the range.

High measurement accuracy

Capacitance, inductance and impedance basic accuracy is 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 clear, large, colour display. Swept parameters are frequency, drive level and DC bias.

Display formats available include series or parallel equivalent circuit.

An Equivalent Circuit Anlysis function is available . This allows modelling and curve fitting to various equivalent circuit models. Four types of three component and a four component model are available. The instrument will calculate the nearest equivalent circuit parameters for the measurement traces and revise the results. Alternatively the component parameters may be entered and the instrument will plot the frequency characteristics.

For single frequency measurements a meter mode is available.

  

Option feature - Polar and Complex Plots & Multi Measurement Mode

 

Variable drive and bias levels

AC drive levels up to 1V or 20mA can be selected to evaluate components in realistic operating environments.

The /D1 DC bias option provides 0 to +40V dc bias voltage and 0 to +100mA dc bias current while the /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. The ability to provide a large screen display 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 stored locally for each mode.

Bin handling

The /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 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 components of leaded components and devices.

1J1012 (2 Terminal) and 1J1014 (4 Terminal) fixtures allow connection to surface mount devices.

Protection against charged capacitors

High 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 capacitors.
