It has nine different reference patterns that can be accessed with a keystroke; these allow performing the basic adjustments of any receiver as well as detecting malfunctions by visually checking the picture. Patterns can be in 4:3 and 16:9 format. The synthesized RF modulator covers the 37-865 MHz range; tuning can be handled by CCIR, OIRT or FCC channelsor directly by frequency, in 50 KHz steps. An electronic attenuator allows a maximum attenuation of 50 dB in 10 dB steps.
