 | START MEAS Initiates a coverage mapping measurement. A valid GPS antenna must be connected to the instrument and enabled for recording measurement data. Note that the START MEAS button is also included in the MEASURE Menu and provides the same functionality. SELECT POINTS Toggle this button to view the value and signal quality of the current measurement. Color-Coded Legend This legend shows the colors that are assigned for each power level threshold. Note that at the end of coverage mapping drive, the legend shows the percentage of breadcrumbs for each of the defined power levels. The power levels can be set using the COLOR SETUP Menu (Mapping). For example, if the power threshold value of the received signal is greater than or equal to -40 dBm, it is indicated in blue color (excellent). If the power value is less than -55 dBm it is indicated in pink color (poor). SELECTED POINT Displays the several parameters of the channel as follows: • CHANNEL: Displays the number of the selected channel. • TYPE: Displays the type of the selected channel • NAME: Displays the name of the selected/custom channel. • FREQUENCY: Displays the center frequency of the sweep range. • SPAN: Displays the sweep frequency range. • DWELL TIME: Displays the time duration spent scanning a given channel. Measurements will complete at the first opportunity greater than the specified time. A 0 µs or no value indicates the measurements complete as fast as possible. • CHANNEL POWER: Displays the channel power of the selected channel measured over the frequency range. • UPPER LIMIT: Displays the default maximum value of channel power. • LOWER LIMIT: Displays the default minimum value of channel power. • AVERAGE: Displays the average value of the total channel power measured over a given channel. • MINIMUM: Displays the minimum value of the channel power measured over a given channel. The black square indicates the color legend that represents the solid black line in the bar chart. • MAXIMUM: Displays the maximum value of the channel power measured over a given channel. The white square indicates the color legend that represents the solid white line in the bar chart. • ROLLING AVERAGE: Displays the rolling average of the channel power for the last 5 seconds of any given channel. • ROLLING MINIMUM: Displays the minimum rolling average value of the channel power for the last 5 seconds of any given channel. • ROLLING MAXIMUM: Displays the maximum rolling average value of the channel power for the last 5 seconds of any given channel. |
CONTINUOUS Performs continuous scan of all the added channels, when toggled on. SCAN ONCE Scans all channels once, when CONTINUOUS is toggled off. FREQ REFERENCE Indicates the current frequency reference source of Internal High Accuracy (used after GPS has lost sync, but while the internal clock still has good GPS reference), Internal Standard Accuracy, External, or GNSS (GPS) Hi Accuracy (requires GPS). The instrument automatically selects the frequency reference in the following order of priority: external, GPS, then the internal time base. |
