Z-Wave 500 series - SOC device and module - Calibration Overview

 
 
 

The Z-Wave 500 series of SOC (System on Chip) devices and modules may require some level of calibration (XTAL or TX calibration) to be performed at the customer production programming stage before the devices / modules will operate correctly. The calibration procedure(s) required depend on whether you are programming a Z-Wave module, SOC (just the bare IC) or 'Bare die' version of the Z-Wave product.

Z-Wave Devices and Modules - cross reference table

 
The table below details which 'calibration procedures' are required for the different Z-Wave 500 series product types....

Cross Reference

Key:

  • YES - The specified calibration method must be carried out by the customer at the 'customer production programming' stage.
     
  • Sigma factory calibrated - The calibration process is carried out by Sigma Designs in their factory so there is no need to recalibrate the device at the 'customer production programming'.

Programmer selection guide for Z-Wave calibration

 
The table below details which Equinox programmers are capable of performing the 'Crystal (XTAL) calibration' and 'TX calibration' procedures.

Programmer Selection

 

Z-Wave (500 series) - Product Types Overview


The Z-Wave 500 series devices are available in various formats including SOCs, pre-assembled modules, SIP modules etc.....

DevicesMoules

Crystal (XTAL) calibration

 
The 'Crystal (XTAL) calibration' procedure tunes the TX- and RX radio frequency of the Z-Wave device so as to give the minimum frequency error. This calibration must be carried out on the final crystal which will be used with the Z-Wave device.

Important notes:

  • The procedure is performed by Sigma at the factory for all Z-Wave modules as these modules have the final crystal already fitted to them.

  • If you are programming SOCs (bare ICs) or 'Bare Die' products, then these devices are NOT pre-calibrated by Sigma at the factory. You will need to perform the procedure on these devices at the customer production programming stage.

TX calibration

 
The 'TX calibration' procedure is required to tune the Z-Wave frequency separation during modulation to an optimum value.

Important notes:

  • The procedure is currently NOT performed by Sigma at the factory.

  • The customer must therefore perform the procedure on ALL Z-Wave modules, SOCs and 'Bare die' devices at the stage.#

Calibration recovery after accidental NVR erasure / corruption

 
If the 'NVR Area' of a Z-Wave 500 series device is accidentally erased or corrupted, then both the 'Crystal (XTAL)' and 'TX' calibration parameters may be be invalid. This means that the Z-Wave device may no longer function properly.

If this happens, then it is necessary to fully re-calibrate the Z-Wave device. This recalibration process involves performing both the 'Crystal (XTAL) calibration' and the 'TX calibration' procedures and also programming some default 'factory settings' for the device or module back into the 'NVR Area' of the device.

This procedure requires the following equipment and other information:

  • An Equinox ISPnano Series 4 ATE or ISPnano-MUX programmer
  • An Equinox 'IOMOD10 - Sigma Calibration Module' - plugged into the programmer
  • ISP-PRO production programming software running on a PC
  • A special 'Restore NVR / recalibrate XTAL / TX' programming script
  • A custom parameter file to restore the relevant 'factory parameters' to the device

Equinox - IOMOD10 - Calibration Module


The 'IOMOD10 - Calibration Module' is a special I/O Connector Module for the ISPnano range of production ISP programmers which support 'XTAL calibration' of Z-Wave 500 series devices and modules.

Please refer to the IOMOD10 page for further details about this module and it's application.
