9.1 Analog output voltages

The analog output voltages are dependent on the open-loop voltage of the operational amplifiers for full-scale conversion

(typical value 1.35 V), the internal series resistor (typical value 2 Ω), the external series resistor and the external load

impedance.

The digital output signals in front of the DACs under nominal conditions occupy different conversion ranges, as indicated

in Table 42 for a 100⁄100 colour bar signal.

Values for the external series resistors result in a 75 Ω load.
