WAVEFORM

creates signal waveforms of various shapes

<out>   Name of output file
<shape> Shape of waveform [DEF=SIN]
<form>  Format of output file (SF, CF, SB, etc.)
<elem>  Number of elements in output file
<rate>  Sample rate in Hz
<gain>  Waveform amplitude (0=nominal for given data type)
<freq>  Waveform (IF) frequency (Hz)
<baud>  Waveform BaudRate frequency (Hz)

This primitive generates the following shaped waveforms:
  Sine     - Sinusoid 
  CoSine   - CoSinusoid 
  Square   - Square waveform 
  Triangle - Triangle waveform 
  SawTooth - Sawtooth or RIGHT triangle waveform
  Pulse    - Single sample pulse
  Constant - Constant values given by nominal value adjusted by gain
  Zero     - Same as CONSTANT with all zeros
  LRS      - Efficient noise generator using a linear recursive sequence
  White    - White noise algorithm with standard deviation of <sdev>. See note below.
  Ramp     - Ramp that increments by one with MAX <amp>-1 and MIN of -<amp>.
  TRamp    - Test Ramp that increments by 3 in the upper byte
  Notch    - LRS with a notch at <freq>.  Use /DFREQ=df to adust width
  MixLS    - Mix of LRS and SIN
  MuxLS    - Mux of LRS and SIN
  MixNS    - Mix of Notch and SIN
  BPSK     - 2 Phase Shift Keyed
  QPSK     - 4 Phase Shift Keyed
  8PSK     - 8 Phase Shift Keyed
  16APSK   - 16 Amplitude+Phase Shift Keyed
  16QAM    - 16 Quadrature Amplitude Modulation
  64QAM    - 64 Quadrature Amplitude Modulation
  128QAM   - 128 Quadrature Amplitude Modulation
  256QAM   - 256 Quadrature Amplitude Modulation

The /RT or /THROTTLE= switch can be applied to simulate a throttled data source.
In FULL mode, the primitive runs as fast as it can.  In REALTIME mode the data
is throttled to be produced at a rate of 1 element per <delta> second(s).
In the BLOCK mode, no data is produced.

Examples:

Switches:
  /RT               - RealTime mode
  /SEED=<num>       - Set seed number [DEF=-1]
  /THROTTLE=<mode>  - Data Throttle Mode (RealTime,Full,Block). Overrides /RT.
  /TL=n             - Transfer Length elements [DEF=4096]
  /FB               - Use page aligned fast buffer 
  /FB=2             - Repeat first buffer of TL elements for speed tests
  /STATS            - Show transfer statistics
  /NTAP=n           - Number of taps in filter (notch or mod resampler)
