The CT-DLM870D is a handheld signal level meter is designed to provide the most valuable features at reduced cost. It performs fast and efficiently to take carrier amplitude measurements. It can also take the direct power measurement of DVB signals. This unit simultaneously displays video carrier, audio carrier strength, V/A measurements, Tilt measurement, C/N measurement and Trunk voltage measurement.


  • Cable Length: 6 ft

  • Trunk voltage measurement

  • Large 2 5/8” x 1 3/4” dot matrix LCD display with back light

  • Battery powered handheld model with internal NiMH battery and included charger

  • Rugged, compact and mobile rubber jacketed housing

  • Up to 8 hours of battery life

  • Direct input by frequency from 5 MHz - 870 Mhz

  • Direct input by channel number

  • DVB average power measurement.

  • Measures QAM 16/32/64/128/256, DVB-C, BER & MER

  • Simultaneously displays video carrier and audio carrier strength, and V/A measurement

  • Switchable between dBmV and dBμV

  • Tilt measurement of three user definable channels

  • Carrier-to-noise ratio measurement


This unit is perfect for balancing digital QAM and analog headend systems, reading digital off air signal levels, troubleshooting RF distribution systems and taking measurements at individual drops. With the ability to read individual audio and video carriers along with line voltage and carrier to noise levels, the CT-DLM870D is perfect for all levels of installers and technicians.

The full-scan option and spectrum option provide the ability to view the carrier amplitude in a full-span display and spectrum analysis. The new digital analysis option adds digital signal testing that includes Bit Error Rate (BER) and Modulation Error Rate (MER). The internal high volume NiMH battery supports up to 5 hours of continuous use after a full charge. This unit is durable and simple to use in a wide range of conditions. The tough plastic housing makes this unit highly resistant to damage from shock and impact. The CT-DLM870D has a 2 5/8” x 1 3/4” enlarged color LCD and the new screen graphics enhance readability and simplify operations.
