GQ-1129/1129D Signal level meter

TV Field Intensity applies to the need of the television and cable television engineering installation and detection, it is the high-performance surveying instrument specially designed for the cable television technical personnel.The instrument adopts the all-number display, the readings on the measuring instrument are clear and precise, and owing to the introduction of the micro processing unit, therefore, it makes its functions stronger, the precision higher, operation more flexible and convenient.

The large screen figure monitor is very convenient to measure the main technical targets of CATV system.

It has the functions such as the single-channel, multi-channel, all-band scanning, difference-carrying measurement, signal-to-noise ratio (SNR, S/N) measurement and spectrum analysis frequency analysis etc.Tuning range:from 5M~862MHzTuning mode:by channels or by frequencyLevel measurementAnalogue channels MeasurementIF bandwidth:280kHz+50kHzInput impedance:75ohmMeasuring range:from 25 to 120 dBuvAccuracy:+2dB (from 0 to 400C)Digital channels MeasurementMER (modulation error ratio) measurement range:19~35dB for 64 QAMAccuracy :+2dBBER (bit error rate) measured before RS decoding measurement range:10E-2 to 10E-8Symbol rate:1MS/S-7MS/SModulations type:16/32/64/128/256QAM DVB-C/ITU-TJ.83-AnnexABandwidth:8MHzFrequency tuner:100 KHzMeasuring range:from 40 to 120 dBuvAccuracy:+3dB (from 0 to 400C)
