class FakeHFB : public kotekan::Stage¶
Generate fake absorber data into a
hfbBuffer.This stage produces fake absorber data that can be used to feed downstream kotekan stages for testing. It fills its buffer with frames in the
HFBFrameViewformat. Frames are generated for a set of frequencies and a cadence specified in the config.- Buffers
out_bufThe kotekan buffer which will be fed, can be any size.Format: hfbBuffer structured

- Param num_beams:
Int. The number of beams in the absorber data.
- Param num_subfreq:
Int. The number of sub-frequencies in the absorber data..
- Param freq_ids:
List of int. The frequency IDs to generate frames for.
- Param start_time:
Double. The start time of the range of data (as a Unix time in seconds). This simply changes the time the frames are labelled with. Default is the current time.
- Param cadence:
Float. The interval of time (in seconds) between frames.
- Param mode:
String. How to fill the absorber array. See the set of FakeHFBPattern implementations for details.
- Param wait:
Bool. Sleep to try and output data at roughly the correct cadence.
- Param num_frames:
Exit after num_frames have been produced. If less than zero, no limit is applied. Default is
-1.- Param zero_weight:
Bool. Set all weights to zero, if this is True. Default is False.
- Param freq:
Array of UInt32. Definition of frequency IDs for mode ‘test_pattern_freq’.
- Param sleep_before:
Float. Sleep for this number of seconds before starting. Useful for allowing other processes to send REST commands. Default is 0s.
- Param sleep_after:
Float. Sleep for this number of seconds after running and before shutting down. Useful for allowing other processes to finish. Default is 1s.
- Param simulate_fpga_restart_at_frame:
Int. If >= 0, resets fpga_seq to 0 at this frame index (for testing countCheck). Default is -1.
- Param end_interrupt:
Bool. Interrupt the kotekan process after num_frames instead of calling exit. Default is False.
