PXe-550 Impedance Calibrator

The PXe-550 Impedance calibrator is a test device designed for LCR meter verification and calibration. The PXe-550 calibrator integrates partial resistance standards in decade series in the range of values from 100 mW up to 100 mW. Capacitance standards in range 10 pF to 100 pF and inductive standards in the range 10 pH to 10 H. For test leads and unit under test electrical zero compensation the calibrator is equipped with reference positions. Short-circuit terminals SHORT and open-circuit terminals OPEN. Summary frequency range covers band from 20 Hz to 1 MHz, however some partial standards have lower applicable frequencies. Partial standards feature low temperature coefficient, excellent long term stability and low frequency dependency.

The PXe-550 calibrator offers two banks of standards. The more accurate bank is equipped with four output BNC connectors. It is aimed for calibration of LCR meters based on auto-balancing bridge principle using four-pair terminal technique (4TP) of test terminal connection. The second bank (4W/2W) is equipped with 4mm output banana terminals. The bank is aimed for calibration of LCR meters based on I-V method with non-coaxial test terminals. Practically this bank can be used in four-wire (4W) or two-wire (2W) measurements.

The PXe-550 has a built-in test signal level meter which can be easily used for verification of test signal voltage, current and frequency. Large front panel colour graphic LCD display show parameters of a selected standard, set-up configuration, calibration data accuracy and another useful information.

Impedance calibrators should be periodically recalibrated. The recommended recalibration interval is 1 year. Internal calibration data is accessible via the front panel keyboard. Calibration memory is protected with a calibration password.

All functions of the PXe-550 calibrator can be controlled by an IEEE-488 interface or via a RS-232 serial line.

Pxe-550 Impedance Calibrator Display

the idea behind the PXe-550 Impedance Calibrator is to replace countless single value LCR standards with one calibrator that can switch between the standards like a CD changer in your car. The calibrator contains stable and temperature independent resistance standards, partial capacitance standards and partial inductance standards, simulated by RC T-type passive network. Calibration values of both complex parameters of partial standards are displayed on large LCD screen in preselected pairs of parameters as well as voltage, current and frequency readouts from built-in test signal meter. OPEN and SHORT reference positions are available as well.
Easy recalibration system offers either full recalibration in all spot frequency points or simplified offset calibration. History of calibration values of partial standards at reference frequency 1 kHz can be easily recalled.

Calibration domain

The Pxe-550 was designed for calibration of LCR meters in frequency range up to 1 MHz. The philosophy of M550 is based on remote control and automated calibration. For this reason, the calibrator is equipped with RS-232 and GPIB interfaces and of course, supported in CALIBER/WinQbase calibration software.
