NAT Release Notes v2.00


The NAT V2.00 and modified PHSNA V3.00 firmware releases add the following features to the NAT–driven PHSNA system:

  • NEW Touch screen support allows nearly all functions to be performed using just the touch screen without requiring a keyboard.

  • NEW PHSNA menu system overhaul integrates the PHSNA menu operations with the NAT touch screen capability providing an easy to use, friendly user interface.  Navigation through the PHSNA menus and prompts has been made easier and more intuitive.

  • NEW Context menus are available to enter all NAT hot-key sequences with the touch screen and can be used as help screens for keyboard users.

  • NEW Function key select menus display the title fields and enable touch screen selection of any of the fourteen function keys for data entry/editing and for initiating PLX operations.

  • NEW 24-key numeric (num) pad display enables touch screen input of numeric data and the entering of edit hot key functions.  Entry in scientific notation is possible in addition to normal signed integer and decimal notations.

  • NEW Signal Generator mode gives the user manual control over the DDS frequency with manual or automatic update of power reading display.

  • Serial Interface baud rate of 38400 bps is now the default.  This was made possible through improved firmware efficiency.  No hardware changes required.

  • File overwrite can now be selected thus eliminating the need to delete spool files before reusing file names.

  • Calibration no longer requires a point-by-point match with the scan data points.  The frequency information used for the calibration scan is saved along with the power levels.  Scan processing will then use the current frequency to locate the nearest point in the calibration buffer.

  • Tighter integration with the modified PHSNA firmware eliminates many of the requirements to reset the Arduino board (UNO or NANO) to initiate an operation.

  • Multi-colored over plots help identify different traces.

  • Added baud rate options of 1200, 2400, and 4800 bps for the serial interface.

  • PHSNA firmware size reduction effort freed a significant amount of Arduino program memory to make room for current and future product enhancements in the NANO’s smaller available program memory space.

  • Miscellaneous bug fixes and user requests were also incorporated in this release.
