All of these capabilities help engineers in the field to detect and diagnose signal quality problems quickly and efficiently.

Wide variety of interface support Click for larger image Wide variety of interface supportIn modern broadcast facilities, there are a wide variety of video and audio signal formats that require multiple tools to monitor the signal. The Telestream WFM-2300 is able to support SD/HD/3G-SDI, AES/EBU digital audio, composite black burst or tri-level sync reference signals and optical SDI (Option SFP), which decreases the need for taking multiple tools to diagnose an issue.

The SDI A input supports SD/HD/3G-SDI (Option 3G) video signals and provides monitoring of eye and jitter measurements. For a Dual Link SDI signal, both the SDI A and MULTI IN inputs are used.

The MULTI IN input also supports SDI, AES/EBU and LTC signals so that the user can easily determine the type of signal present on a cable.

The AES OUT and SDI OUT connectors are test signal outputs that can be configured as loop through output. The individual outputs for Audio and Video in conjunction with the SDI A and MULTI IN inputs allow the user to evaluate the variety of Audio/Video equipment that may require the audio/video signal with separate path.

The REF IN connector is used for receiving the analog composite or tri-level sync signal to measure the timing or check the sync status between sync signal and SDI signals. It is also used as a Genlock signal source for the generator function. In addition, the analog reference signal connected to this connector can be displayed as a waveform to quickly check the quality of the sync signal.

The optical SDI interface (Option SFP) is supported with a transceiver SFP module. The transceiver module provides both an input and output that can be used simultaneously. The output can be configured as loop output or as a test signal output. The SFP status display shows the module model name, mode, temperature and other status of the SFP module.

The STRESS LOOP connectors are a bi-directional passive signal path that can be used with a SDI test signal generated by the Telestream WFM2300 to test a signal path, or to add an additional cable length and interfering signal to a signal path to provide simple margin testing.

Quickly diagnose and isolate an installation issue

Within a broadcast facility, to maintain the SDI system it is important to ensure the health of the signal so that the clock and data are decoded correctly. CRC detection within the SDI signal can be used to count the CRC errors if present in the system. The measurement, however, may take minutes or hours to ensure that the signal is error free.

The cable stress/margin loop adds an additional 20 meters of cable and an interfering signal to the signal path. The use of the stress/margin loop along with CRC detection simplifies how to determine the cable margin of a system so that the user can quickly ensure they do not reach the "digital cliff" where the transmission error rate significantly increases.
