Keysight M8194A 120 GSa/s Arbitrary Waveform Generator User Guide 71
M8194A Soft Front Panel 3
• Ch. 3 (Marker 2)
Marker 2 is output on Channel 3. Signaling the beginning of the
Channel 1 waveform may be activated (Segment selection) and
deactivated (None selection).
Scaling Section
• DAC Max
Standard 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
Standard 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.
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.
• 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.
