RF Probe for VHF & UHF

RF TV level alarms

RFTV is a low-cost RF level converter, suitable for any UHF TV equipment with an output power test-point.

The output level is continuous and, to obtain the best precision on the entire scale, is corrected by ANT SW. These converters are connected directly to the RF output test point of the equipment. RFTV has two operating modes: Reading or Alarm.

  • In reading mode, you can read the output voltage proportional to the RF input level
  • In alarm mode, the probe works like an open contact: when the reading of the equipment under control is lower than a preset level, a contact to ground is closed.

Frequency Range: 400 ÷ 900 MHz

Output Range Reading mode: 0 ÷ 5 Vdc

Alarm mode: Contact to ground closure
