The following steps show how to capture data using
the HSDC Pro software (see Figure 3-4):
- Select the test to
perform.
- Select the data view.
- Select the channel to
view.
- 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.
When using decimation and NCO features, click the
gear symbol to access the Additional Device Parameters dialog box to enter
the following details:
- ADC Sampling Rate
- ADC Input Signal Frequency
- NCO Frequency
- Decimation Factor
The HSDC Pro GUI will calculate the ADC Output Data Rate based on these inputs. The Fundamental and Harmonic frequency locations will also be calculated and identified in the FFT display.
