Analog TV Monitoring Receiver

The ATMR-700 is designed for monitoring analog TV transmitters

Continuously checks the quality of service for up to 8 channels in an area and it performs QOS measurements for all TV systems (NTSC/PAL and SECAM) and all bands (VHF low, VHF high and UHF). Here are some examples: RF level, sync tip level, burst flag level, audio average, audio peak and offset frequency, …

FEATURES

The card offers a video and audio output monitor and performs intelligent monitoring: detects audio loss, sync loss, video dark, etc. for up to 8 programmable channels.

There are 2 possible specialized functionalities that can be programmed; these will be executed in real time by the ANT132 and will report abnormalities to the RDF:

• Real time monitoring of one or more channels: This puts the card as a watchdog on one or more specified channels; all parameters are monitored and reported to the RDF that will report to the control-center in case of abnormal readings
• Real time monitoring of the whole TV spectrum: This specialized function doesn’t monitor every parameter of each channel present in that moment in the spectrum, but will only report the presence of channels. In other words, if suddenly a channel (that was there shortly before) disappears, or if a channel that wasn’t present, suddenly pops up, it will be reported
