GV-798+ Description
GV-798+ and GV-898+ TV signal generators have the widest selection of functions for an instrument of this type, including the possibility to generate YPb Pr signals. Multistandard and multi-system, 37 different patterns, 16:9 and 3:4 formats, VITS & WSS, teletext, VPS and PDC. Possibility to display messages (clock, text).

All common interface connectors such as S-VHS or SCART are available; the RS-232 interface is specially useful being bidirectional to control the instrument and for data exchange. Output level of up to 80 dBmV with a progressive attenuation in steps of 1 dB.

Specially indicated for those applications where a high quality signal is required, such as adjustment and verification lines, production studios, industrial applications, investigation centers, etc.

The only difference between GV-798+ and GV-898+ models is the RF modulator. The GV-798+ uses a double sideband (DSB) type while GV-898+ uses a vestigial sideband (VSB) approach, similar to the ones used for TV signals broadcast.
