Code Scan: Press this submenu key to display the 32 sync codes in table format. Displayed below the table are DwPTS Power (in dBm) and Pilot Dominance (in dB).
Tau Scan: Press this submenu key to display the code power versus Tau in bar graph format. Code numbers are displayed at the top of each bar. A table below the bar graph shows the 6 strongest codes (identified by number) and the Tau (in µs) and the Ec/Io (in dB).
Record Off/On: Pressing this submenu key so that On is underlined (selected) sets the instrument to automatically record all OTA measurements that are taken while in the Run mode. Before recording occurs, the name of a log file is flashed on the screen. This is the file in which all recorded data is stored. Selecting Off stops all recording and closes the log file. When pressed again, recording begins in a new file. If Record is turned On when the measurement is a non‑OTA measurement (such as Spectrum), then no action is performed.
Run/Hold: Press this submenu key to set either Run mode or Hold mode. Hold mode prevents the instrument from taking any new measurements and freezes the current measurement. Run mode allows the instrument to continually take measurements.
When Record is already toggled On, pressing the Run/Hold submenu key toggles the taking of measurements on and off to continue appending new measurements within the same log file, rather than creating a new log file.
Back: Press this submenu key to return to the Measurements Menu.
