Marker Usage - Up to 2 markers can be used to view data point details or deltas between 2 data points on the
graph. The active marker, the one with user input focus, is in red and the inactive marker is in black.
Marker Keys :
•
Up Arrow – Place the active marker at the maximum value (the highest peak).
•
Left Arrow – Move the active marker to the previous point. Tap to move one point at a time or hold to
incrementally skip points.
•
Right Arrow – Move the active marker to the next point. Tap to move one point at a time or hold to incre-
mentally skip points.
•
E – On/Off – Enable or disable the active marker.
•
P – Cycle through peaks, placing the active marker at the next peak.
•
1 – Activate (and enable) marker number 1.
•
2 – Activate (and enable) marker number 2.
Viewing Data in a Table of Peaks
The peak table view displays the peak values most recently located in the sweep in a tabular form. The fields are:
•
Sweep - The sweep number - a count of how many sweep have been made since the acquisition was
started.
•
Timestamp - The time the sweep dataset was captured from the BDS receiver.
•
Elapsed (ms) - The time (in milliseconds) between sweeps, 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 sweep data 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.
•
Peak – The peak number. Peaks are listed in ascending order (highest to lowest).
•
F (Hz) – The frequency of the peak in Hz.
Selected amplitude. One of the following:
•
Vrms (Volts) – RMS voltage.
•
Irms (Amps) – RMS current.
•
Z (Ohms) – Impedance in Ohms.
•
P (Watts) – Power in Watts.
•
P (dBm) – Power in dBm.
