05 db 50 Hz to 14 khz btsc typical at second equivalent input modulation within the Belar tvm 230 btsc tv stereo monitor provides an rs 232 port, permitting full operation and readout under computer control. Belar model tvm 230 digital btsc tv stereo monitor analyzer the Belar tvm 230 is a digital btsc tv stereo monitor analyzer. Settings under menu control include peak flasher parameters, l r channel commanding, and selection between the two monitor inputs. The tvm 230 also indicates peak level of the stereo composite signal and pilot injection.
Specifications inputs two wide band demodulated aural composite, delectable from front panel input level Belar. The tvm 230 may also be used in conjunction with other Belar monitors via the wizard interface.
The wizard system turns an ordinary PC into a powerful tool for the display and logging of btsc tv stereo modulation parameters. 1 signal input to output delay 5 milliseconds dimensions 1 IA rack unit Unlike analog designs, this DPs based design is immune to variations due to temperature or the aging and tolerance of components.
Readings of the left, right, l r, l r signals, along with total, are provided both as peak percentages and relative decibel db indications. Rear panel outputs include relay closures for the front panel alarms, and analog signals to drive the optional stereo remote meter panel. The tvm 230 digitizes the complete demodulated aural signal and decodes the stereo multiplex portion using digital signal processing techniques. One pair of up down keys provides menu control, another pair of keys adjusts operating parameters.
