Digital QAM Signal Analysis Meter

The Pico-Pro/Q signal analysis meter is a portable, high-performance QAM or analog signal meter specifically designed and manufactured to meet the requirements of modern day CATV systems. The PICO-PRO/Q can test the CATV QAM or analog signals in the scan, spectrum, or channel modes. In the analog mode, the unit will measure video carrier, audio carrier, A/V ratio, and C/N ratio. In the digital mode, it will measure BER, MER of QAM 16, 32, 64, and 256 in ANNEX B, and QAM 16, 32, 64, 128, and 256 in ANNEX A mode. The Pico-Pro/Q will display a constellation of the measured digital signals. CATV cable tilt and trunk AC voltage can also be measured with this unit.

The Pico-Pro/Q features a large 2.4-inch by 1.8-inch LCD that conveniently displays all the measurements and graphs for easy interpretation. The data logging capability of the Pico-Pro/Q allows measurements made in the field to be conveniently retrieved by a computer using an RS-232 interface. When fully charged, the Pico-Pro/Q provides continuous and reliable operation up to five hours in the field.
