Locator objects contain information about the tuning space. Locator objects are generally used by the Network Provider filter to help a tuner find and acquire the transport stream. Applications do not use Locator objects except possibly for debugging purposes.
Method or Property Name Description CarrierFrequency Sets or retrieves the carrier frequency(DecaHertz). Clone Copies the Locator. InnerFEC Sets or retrieves the inner FEC type. InnerFECRate Sets or retrieves the inner FEC rate. Modulation Sets or retrieves the modulation type. OuterFEC Sets or retrieves the outer FEC type. OuterFECRate Sets or retrieves the outer FEC rate. SymbolRate Sets or retrieves the QPSK symbol rate.

Syntax
Locator.OuterFECRate
Remarks
This property is read-write.

Sets or retrieves the QPSK symbol rate.
Syntax
Locator.SymbolRate
Remarks
This property is read-write. QPSK modulates symbols onto the RF signal. These symbols are detected by the demodulator and used to reconstruct a bit stream. QPSK allows the rate at which symbols are (de)modulated to be changed.
