Viewing the Data
Data can be viewed while it’s being collected or after a data acquisition completes. The data is displayed in the fol-
lowing formats:
•
Table
•
Time plot
•
Reconstructed waveform
•
Smith chart
These views can be accessed and switched at any time by:
•
Selecting a different view using the buttons on the View tool bar (Figure ).
•
Right-clicking anywhere on a view and choosing from the pop-up menu.
•
Selecting View and your choice from the main menu.

Figure 7 Data in Tabular Format and View Selection Buttons
The table view displays the most recently collected dataset in tabular form. The fields are described in detail below:
•
Dataset - The dataset number - a count of how many datasets have been received for the document.
•
Timestamp - The time the dataset was captured from the BDS receiver.
•
Elapsed (ms) - The time (in milliseconds) between measurement datasets, giving an indication of data
update rate.
•
AGC - Automatic gain control indicator.
Note: Displays “Yes” if automatic gain control is used or “No” if manual gain control is used.
•
Cal – Measurement calibration indicator.
Note: Displays “Yes” if the displayed measurement dataset has been calibrated or “No” if it has not been
calibrated.
Note: Check the probe connection to the receiver if the BDS GUI is indicating that the measurements are
not being calibrated.
•
Arc - Arc detected during the displayed measurement cycle.
Note: This will display “No” if no transient event has been detected or “Yes” with a red background if a
transient has been detected during the measurement cycle.
The data table displays the following information for each harmonic component returned in the dataset:
•
F (Hz) - The estimated frequency in Hz. This is the frequency reported by the BDS receiver.
