SPG8000ANT - Overview

The SPG8000A is a precision multiformat video signal generator, suitable for master synchronization and reference applications. It provides multiple video reference signals, such as black burst, HD tri-level sync, and serial digital and composite analog test patterns, and it provides time reference signals such as time code, NTP (Network Time Protocol), and IEEE 1588 PTP (Precision Time Protocol). The base configuration includes three sync outputs that can be configured with independent output formats and independently adjustable timing offsets.

Option GPS adds an integrated receiver to the SPG8000A that is capable of receiving both GPS and GLONASS signals. When connected to an external antenna that supplies the standard GPS and/or GLONASS RF signal (for example, SPG8000ANT), the SPG8000A can use the GPS?/?GLONASS system’s stable frequency reference.

The GPS/GLONASS signal also includes a precise time-of-day reference that can be used for all time code outputs. Similar to the Stay GenLock feature, the SPG8000A can maintain the video frequency and phase when the GPS/GLONASS signal is interrupted, and the Holdover Recovery mode will ensure a shock-free realignment of frequency and phase when the GPS/GLONASS signal is restored.

Please note! This item is an add-on "option" to the Tektronix SPG8000A Master Sync / Master Clock Reference Generator. The SPG8000A is required and sold separately. Image is for reference only!
