Acquisition steps (using HTTP GET methods)

This example shows how to perform a signal acquisition with node 2.
Therefore, the following steps will only work if node 2 is online and available.

• Step 1. Receiver FPGA programming.

/testbed/node2/wsLyrtech.asmx/adc_FPGAConf?fileName=ADC_Virtex4_8_channels_RFFE.bit

• Step 2. Initialize RF frontend.

/testbed/node2/wsLyrtech.asmx/rffe_Init?LPFCornerFreq=24&RF_Freq=2462

• Step 3. Adjust transceiver #1 LNA Gain and VGA Gain.

/testbed/node2/wsLyrtech.asmx/rffe_RxGain?LNA_Gain=3&VGA_Gain=5&Transceiver=1

• Step 4. Set ADC board sampling frequency to 52 Mhz.

/testbed/node2/wsLyrtech.asmx/adc_SamplingFreq?SamplingFreq=52

• Step 5. Configure ADC board to acquire 100 samples through channels 1 and 2 (I and Q branches of the transceiver #1).

/testbed/node2/wsLyrtech.asmx/adc_ChannelConf?ChannelMask=3&SamplesPerChannel=100

• Step 6. Acquire and save the samples into the SDRAM. Then, send the data to the user that executes this call.

/testbed/node2/wsLyrtech.asmx/adc_Acquire_SDRAMRead?SamplesPerChannel=100

• Step 7. Translate received data from base64 to int16 to see the samples acquired by the ADCs.
