Setup Procedure
2.12 Capture Data Using the HSDC Pro Software
shows the HSDC Pro GUI. The following steps show how to capture data using the HSDC Pro
software (see ):
1. Select the test to perform.
2. Select the data view.
3. Select the channel to view.
4. Click the
Capture
button to capture new data.
Additional tips:
•
Use the
Notch Frequency Bins
from the
Test Options
file menu to remove bins around DC (eliminate
DC noise and offset) or the fundamental (eliminate phase noise from signal generators).
•
Open the
Capture Option
dialog from the
Data Capture Options
file menu to change the capture depth
or to enable Continuous Capture or FFT averaging.
•
For analyzing only a portion of the spectrum, use the
Single Tone
test with the
Bandwidth Integration
Markers
from the
Test Options
file menu. The
Channel Power
test is also useful.
•
For analyzing only a subset of the captured data, set the
Analysis Window (samples)
setting to a value
less than the number of total samples captured and move the green or red markers in the small
transient data window at the top of the screen to select the data subset of interest.
