Figure 13-4: Example: Processing of MARKER TRACE if CONTROL LENGHT is specified
If the CONTROL LENGTH tag is not used, the marker and control list length are deter-
mined by the last position, that is the last {Pos:State} couple, defined in the particular
[TRACE] LIST tag; see Figure 13-5.
Figure 13-5: Example: Processing of MARKER TRACE if CONTROL LENGHT is not used
To maintain marker signals and waveform data synchronized, set the CONTROL
LENGTH to be equal to the number of samples specified with the tag SAMPLES.
See also "How to Define Periodically Repeating Traces" on page 974.
Example:
{CONTROL LENGTH: 500}
SOURce:BB:ARBitary:CLISt:TAG? 'CONTROL LENGTH'
Queries the length of the control list.
Response: 500
Manual operation: See "Total List Length" on page 284
{LEVEL OFFS: RMSOffset_dB,PeakOffset_dB}
(recommended for waveforms)
The tag determines the level of the ARB signal in the waveform file. The offset levels
define the offset of RMS and peak value relative to the 16-bit full scale modulation
(-32767 to + 32767) = 0 dB.
Setting parameters:
RMSOffset_dB Defines the RMS level offset of the signal relative to full scale
ARB signal in the WAVEFORM tag. The offset is defined in ASCII
float format. The value is always positive.
A 3 dB value indicates that the RMS level of the signal is 3 dBs
below the full scale.
full scale = max. amplitude of vector of I/Q samples = |S
