ADRV9001 EVALUATION SYSTEM
Change the capture length in number of samples.
►
Change the receiver gain level (gain table index).
►
Change the receiver interface gain (in four steps).
►
Enable/disable the "Baseband DC Rejection" tracking calibration.
►
Change the frequency offset in Hz.
►
Read back the main parameters measured in received signals, such as the fundamental frequency, its amplitude, and DC offset.
►
Plot and save the received data by clicking the floppy disk icon in the bottom left corner.
►
Save the receiver-captured data (specified in the "Capture Length" window) as a *.csv or .tsv file.
►
There is an interleaving option pop-up window displayed when saving as a .tsv file.
►
Pressing the play symbols enables the selected receivers and displays the received data continuously until Stop is pressed.
If the receiver frequency deviation is enabled in the configuration step, the receiver input signal is demodulated. For example, if a continuous
wave of 900.003 MHz is sent to the RX port with an LO of 900 MHz, there is a tone of 3 kHz offset from LO in the baseband, and on the RX tab
it is expected to see a constant of 3000 in the time domain plot.
See Figure 309 for options on the captured data format.
Save the receiver-captured data using Save next to Play. Save the data in either the .txt or .csv format. Each column corresponds to one
channel. The data samples follow the Q1.15 fixed point format upon selecting the interleaved option. The following shows this.
