n Return Value
Deviation (RMS) Max Hold (Hz)
Burst length of the Analyzed Burst (s)
Start Time of the Analyzed Burst (s)
Preamble Length of the Analyzed Burst (the time elapse from the first preamble chirp to the start of the first
header chirp) (s)
Payload Length of the Analyzed Burst (the time elapse from the first header chirp to the end of the analyzed
burst) (s)
RMS Frequency Drift (Hz)
Frequency Drift (Peak+) (Hz)
Frequency Drift (Peak+) Max Hold (Hz)
Frequency Drift (Peak -) (Hz)
Frequency Drift (Peak -) Min Hold (Hz)
Sync Byte #1 (decimal)
Sync Byte #2 (decimal)
Payload CRC state
If Decode Enable is On:
1: Pass; 0: Fail; -999: Unknown
Otherwise:
-999
Header CRC state
If Decode Enable is On and Implicit Header is Off:
1: Pass; 0: Fail; -999: Unknown
Otherwise:
-999
Decoded Payload Data Length (in Byte)
Decoded Coding Rate
When Decode Enable is On and Implicit Header is Off:
0: 4/5 | 1: 4/6 | 2: 4/7 | 3: 4/8 | 4: 4/5 LI |5: 4/6 LI |6: 4/7 LI
If the decoded value is beyond the range above, its actual value will be returned
When Decode Enable is Off or Implicit Header is On:
-999
Decoded Payload CRC State
When Decode Enable is On and Implicit Header is Off:
0: Off
1: On
Otherwise:
-999
2 This query returns the min demod trace data as a list of x,y pairs. The x-axis values are in units of seconds.
