The Tektronix 1410 Series NTSC Sync and Test Signal Generator is a precision generator for use in studios, remote vans, maintenance facilities and anywhere where high quality sync and test signals are needed. The 1410 include a genlock sync generator and can configured with up to five of any combination of five signal generators and one signal switcher. The Tektronix 1410 NTSC Mainframe generates chrominance subcarrier at 3.579545MHz ±10Hz. Each ±1Hz color standard has a proportional control oven for the oscillator circuit. A front-panel lamp indicates proper operation of the oven. This instrument comes with one SPG2 sync pulse generator. The SPG2 has an output amplitude of 2 Vp-p into 75-ohms, & composite video amplitude of 1 V into 75-ohms. It uses either internally generated or externally supplied subcarrier for color standard reference. Subcarrier source is front panel selectable. The SPG2 comes with two external synchronization modes, external reference & Genlock. The input requirements for the sync source is 1 V nominal composite video or black burst, sync negative with sync amplitude of 286 mV ±6 dB & burst amplitude of 286 mV ±12 dB. Delivery includes the following plug-ins : SPG2, TSG7, TSP1, TSG3, TSG5, TSG6
