A new product from the Designer of the DG8SAQ Low Cost 1.3 GHz Vector Network Analyzer, the Magi-Cal® is an automated SMA Calibrator for use with the VNWA 3 Series.

Normally, the VNWA calibration process involves a number of connect/disconnect cycles of the various calibration standards.This is time consuming and can be prone to handling errors - Measurement results with vector network analyzers are only as good as the quality of the performed calibration.

The Magi-Cal® performs an automatic one port or two port VNWA calibration with a single connect cycle.

Covering the full frequency range of the VNWA, the Magi-Cal® offers a high quality of calibration that is on par with what can be achieved with Premium Calibration parts.
Calibration accuracy is dependent on VNWA performance, which provides good quality measurements up to 500 MHz, somewhat reduced accuracy between 500-1000 MHz and useable performance between 1000-1300 MHz.

Each Magi-Cal® device is individually commissioned and calibrated, and the model parameters are stored within the Magi-Cal® hardware itself. This gives the added benefit that the unit can be quickly and easily used to calibrate multiple VNWAs.

• The Magi-Cal® device contains two sets of reflect calibration standards for either rf port, and a thru calibration standard potentially connecting port 1 to port 2.

• The standards can be connected internally to the two ports via USB control

• Upon connecting the Magi-Cal® to a computer USB socket, the LED indicates functionality of the device by briefly flashing up in the sequence red-orange-green-OFF
