LO PLL USB MAX2871 ADF4350 ADF4351

The frequency synthesizer supports several operating modes:

  • signal source controlled from the PC;
  • autonomous signal source which can generate four frequencies preprogrammed by the user;
  • beacon, which can send CW text/tones and scan up to four frequencies.

All beacon parameters are user programmable with help of our PLL software included in this KIT.

Ver. 3.6 (Release date — 2019-05-16):
https://vhfdesign.com/data/zip/SynProg-v3-6.zip
– Fixed. Now the synthesizer turns off normally when working on the second band.
– Added “demo” mode. Select the item “Demo” in the “Port” list and click “Connect”.

Ver. 3.5 (Release date — 2019-04-28):
https://vhfdesign.com/data/zip/SynProg-v3-5.zip
– Frequencies outside the synthesizer chip frequency range can be saved to the board flash memory (for example, 6010MHz or 12024MHz);
– Frequencies outside the synthesizer chip frequency range are highlighted with orange background;
– The synthesizer chip output power is fixed at -1dBm for the 2nd band to conform doubler chip specifications (SHF boards only);
– Fixed a bug with incorrect band selection when reading a configuration from the file (SHF boards only);
– Frequency tuning with a mouse wheel and UP/DOWN keys. Just place the caret on the digit you want to change and turn the mouse wheel or press UP/DOWN keys;
– COM ports list refreshes “on the fly”.

Ver. 3.4 (Release date — 2019-03-21):
https://vhfdesign.com/data/zip/SynProg-v3-4.zip
