Audio Generators
The 7400 and 9400 provide extensive support for analog and digital audio. Because all of the video
outputs can be locked to a common time base, the AES digital audio outputs are always synchronous
with all of the video outputs – regardless of format. Multiple tone generators make it easy to identify
multi-channel content. This bitstream will be included in the set of signals that can be embedded into
the test signal outputs.
The audio section of each generator supports sixteen audio channels. The content of each channel is
independently programmable. Choices include adjustable frequency tone generators, tone sweeps,
Silence, Timecode, Audio Clip playback from Secure Digital Card, and the external AES input. Left/Right
Channel ID that synchronizes to the Cyclops feature can also be selected.
All sixteen of these channels can be embedded in the SDI outputs. Each AES output can select
from any of the 8 pairs that make up these 16 channels. Similarly, the stereo analog output of each
generator can be driven from any of these audio signal pairs.
Multiple Timecode Generators
Multiple timecode generators make the 7400 and 9400 convenient for post applications. Timecode
is delivered as LTC (both 75 Ohm BNC and 110 Ohm Balanced), VITC, and DVITC. One generator
can be configured to produce 525/59.94 drop frame timecode while the other generator is making
1080sF/23.98.
