Preliminary Technical Data UG-1828
Rev. PrB | Page 105 of 277
3. ADRV9001 TES includes several pre-defined examples in the /Examples folder.
Rx Only
1. Select the pre-defined json file DMR_24K_RX_ONLY_FH.json
2. Hop Pin should be set automatically.
3. Go to Receive tab, set the capture length to longer value. Here we set it to 65536.
4. Click play
You should see the signal being played for multiple frequencies.
Note in the time domain, TES only shows actual data frames, that is without gap between data frames.
Figure 111. Rx TDD DMR with Frequency Hopping
Tx Only
Steps are the same as Rx Only, except the pre-defined json file must be DMR_24K_RX_ONLY_FH.json
We use 0 Hz tone as an example, here we see the 6 frequencies, the plot is done with max hold.
Figure 112. Tx TDD DMR with Frequency Hopping
TRx
Steps are the same as Tx Only or Rx Only, except the pre-defined json file must be DMR_24K_TX_RX_FH.json
In this mode, the frames are interleaved between Tx and Rx. Therefore, from time domain, the Tx spectrum analyzer should show gaps
between frames.
