Scaling Section
 DAC Max
Waveforms may occupy a limited range of the DAC’s full scale. This parameter sets
the maximum level. If set to a lower level than DAC Min, this will be automatically
set to the same level. Acceptable range for this parameter is -1/+1, being the full
dynamic range of the instrument’s DAC.
 DAC Min
Waveforms may occupy a limited range of the DAC’s full scale. This parameter sets
the minimum level. If set to a higher level than DAC Max, this will be automatically
set to the same level. Acceptable range for this parameter is -1/+1, being the full
dynamic range of the instrument’s DAC.
Marker Section
 Sample Marker
Sample marker signaling the beginning of each segment may be activated
(Segment selection) and deactivated (None selection).
 Sync Marker
Sync marker signaling the beginning of each segment may be activated (Segment
selection) and deactivated (None selection).
Constellation Diagram Section
The constellation diagram section shows a graphic representation of the ideal
constellation corresponding to the selected modulation scheme and modulation
parameters. It also shows the location of symbols from valid modulation definition
files for validation. The line above the constellation diagram shows the following
modulation parameters:
 BPS (Bits Per Symbol)
 Per symbol rotation angle (in degrees)
 I/Q delay (in symbol times)
Compilation and Panel Control Section
 Save To File…
Signals can be stored in files in whether BIN (for non IQ modes) or IQBIN (for IQ
modes) formats. These files may be reused within the Import Waveform tab. This
button is not active if File Format is the "SigStudioEncrypted".
 Send To Instrument
Signal will be transferred to the selected segments of the selected channels. The
previous running status for the target instrument will be preserved but sampling
rate may be modified depending on the waveform requirements.
 Set Default
All the Multi-Tone waveform parameters are set automatically to their
corresponding default values. Entries in the Arbitrary Tone table are not modified
by this button.
 Abort
This button allows canceling signal calculation at any moment. It only shows up
during signal compilation.
