gr-m2k

gr-m2k contains blocks that represent all major components of ADAML-2000. These GNU Radio blocks are build around ADI's libm2k library.

gr-m2k offers the possibility of interfacing with a variety of peripherals, in order to use the ADALM2000 as a master to configure/use them.

How to build it?

Linux

Dependencies

Download and build gr-m2k 

git clone https://github.com/analogdevicesinc/gr-m2k.git
cd gr-m2k
mkdir build
cd build
cmake ..
make 
sudo make install
cd ../..
sudo ldconfig

In order to use the digital interfaces please enable the digital option: 

cmake -DDIGITAL=ON ..
make 
sudo make install

Blocks

Common

  • uri: Describes the context location: usb:XX.XX.X, ip: XXX.XXX.XXX.XXX

M2k Analog In Source

Controls the analogical input component of ADALM2000.

  • Buffer size: Size of the internal buffer in samples.
  • Enable ch 1: Enables the receive data path for the first channel.
  • Enable ch 2: Enables the receive data path for the second channel.
  • Range ch1: Selects one of the available ranges: low, high
  • Range ch2: Selects one of the available ranges: low, high
  • Calibrate ADC: Calibrates the ADC
  • Stream voltage: Set to “true” in order to stream processed values, converted into volts.
  • Sampling frequency: Frequency at which the hardware will input samples - 1000, 10000, 100000, 1000000, 10000000, 100000000
  • Oversampling ratio: Oversamples the signal with the given integer factor.
  • Kernel buffers: The number of the internal buffers.
  • Trigger condition ch 1: Selects one of the available conditions: rising edge, falling edge, low level, high level
  • Trigger condition ch 2: Selects one of the available conditions: rising edge, falling edge, low level, high level
  • Trigger mode ch 1: Selects one of the available modes: always, analog
  • Trigger mode ch 2: Selects one of the available modes: always, analog
  • Trigger source: Selects one of the available sources: channel 1, channel 2, channel 1 or channel 2, channel 1 and channel 2, channel 1 xor channel 2
  • Trigger delay: The number of samples in buffer before the triggered sample.
  • Trigger level ch 1: The value in volts in which the triggering condition should be reach.
  • Trigger level ch 1: The value in volts in which the triggering condition should be reach.

M2k Analog Out Sink

Controls the analogical output component of ADALM2000.

  • Buffer size: Size of the internal buffer in samples for both channels.
  • Cyclic channel 1: Set to “true” if the “cyclic” mode is desired. In this case, the first buffer of samples will be repeated.
  • Cyclic channel 2: Set to “true” if the “cyclic” mode is desired. In this case, the first buffer of samples will be repeated.
  • Calibrate DAC: Calibrates both DACs.
  • Stream voltage: Set to “true” in order to stream processed values, converted into volts.
  • Sampling frequency ch1: Frequency at which the hardware will output samples - 750, 7500, 75000, 750000, 7500000, 75000000
  • Sampling frequency ch2: Frequency at which the hardware will output samples - 750, 7500, 75000, 750000, 7500000, 75000000
  • Oversampling ratio ch1: Oversamples the first signal with the given integer factor.
  • Oversampling ratio ch1: Oversamples the second signal with the given integer factor.
  • Kernel buffers ch 1: The number of the internal buffers of the first channel.
  • Kernel buffers ch 1: The number of the internal buffers of the second channel.

M2k Analog In Converter

Converts raw ADC samples into voltage values

M2k Analog Out Converter

Converts raw DAC samples into voltage values.

Examples

Loopback

In this example we are going to generate two signal(sine and square) using ADALM2000. These signal will be read back and plotted.

  • Hardware setup:
  1+ ---> W1
  2+ ---> W2
  • Flowgraph:
