• Ch. 4 (Marker 2)
Marker 2 is output on Channel 4. Signaling the beginning of the
Channel 1 waveform may be activated (Segment selection) and
deactivated (None selection).
Scaling Section
• DAC Max
Multi-Tone 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
Multi-Tone 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.
Crest Factor Section
It is an indicator only.
It shows the estimated PAPR for the current waveform in dB. Although the
definition of the PAPR parameter is always the ratio between the peak and
the average power for a signal, results change depending on the working
mode. For the I/Q Data Generation mode, the result reflects the PAPR of
the envelope of the resulting signal while for direct generation it reflects
the overall signal. The difference between the former and the latter values
is close to +3dBs in most cases.
Preview Section
• Multi-Tone Preview Toolbar
The waveform preview toolbar includes the icons that provide different
functionality to preview the waveform. For details, see Preview Section
on page 55.
Compilation and Panel Control Section
• Save To File…
Signals can be stored in files either in BIN (for non IQ modes) or IQBIN
(for IQ modes) formats. These files may be reused within the Import
Waveform tab.
