5821-D Delay Characteristics

The processing delay varies with the type of conversion being performed. The charts below list the
electrical length or processing time for the HD/SD-SDI and Analog HD/SD outputs. Select the input rate
on the left and the output rate and type on the top. The intersecting box contains the conversion time
information.
f = field; F = Frame – Delay rates (in f or F) are shown with respect to the input signal.
