Digital Audio Test Equipment –
The CT-4SM monitors Digital Audio signal quality on up to 4 digital audio streams (8 channels) simultaneously. The CT-4SM checks for signal integrity, type, and parity. The unit tolerates a single parity error typical of switching from one source to another, but will not tolerate multiple parity errors typical of a faulty or noisy data line.
The CT-4SM provides verification of signal quality back to the signal source. The CT-4SM also aids in finding the root of a problem without unnecessary false alarms.
Status LEDS indicate which channel faulted and caused an alarm. The LEDS indicate the faulted channel and if the fault still exists. The CT-4SM effectively traps and indicates intermittent conditions.
Each of the four streams may be asynchronous (different clock reference/phase) with respect to the other streams.
Active channels are either GREEN (Good) or RED (Fault). CT-4SM auto-detects unused channels and turns unused channel LEDS off.
