box in case different waveforms from different SGFP tabs shall be
downloaded to different channels. Record length are calculated to
contain an integer number of complete PRBS sequences except when
the “Set WL to Max” is selected. In this case the number of symbols in
the resulting waveform will be the closest integer for the signaling rate
set by the user. As a result, signaling rate will be adjusted, if necessary,
so it is consistent with the resulting time window (Time Window =
Record Length * Sampling Rate).
•
Sample Rate
Indicator only. It is the final DAC conversion rate for the resulting signal.
It is automatically calculated depending on other signal parameters if
the “Keep Sample Rate” check box is not selected.
Marker Mode
These controls are available when the “Single Channel with Marker” or
“Dual Channel with Marker” mode is selected in the
Output
tab. See
•
Ch. 2 (Marker 1)
Marker 1 is output on Channel 2. Signaling the beginning of the
Channel 1 waveform may be activated (Segment selection) and
deactivated (None selection).
•
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.
