Description

WV Communications 70-01FM-CH FM Modulation Sensitivity Adjust 70MHz RF

This is a benchtop FM modulation sensitivity adjustment unit operating at 70 MHz. It provides manual control over FM modulation sensitivity settings via a front-panel rotary trim potentiometer, with status indication via power and fault LEDs.

Specifications & What's Included

  • Model: 70-01FM-CH (Secondary: 70MDF-FM-BRZ)
  • Frequency: 70 MHz
  • Power: 115 VAC, 1-phase, 47–63 Hz, 1 A
  • RF Output: BNC connector (J2)
  • Tone Input: BNC connector (J1)
  • Control: DB9 connector (J4)
  • AC Input: IEC C14 (J3)
  • Front Panel: AC PWR ON (green LED), FAULT (red LED), FM Modulation Sensitivity rotary trim pot
  • Unit only; no accessories included

Applications

FM modulation adjustment units like this were used in telecommunications and RF test environments for 70 MHz systems, particularly in microwave link and repeater configurations. The device allows technicians to calibrate modulation depth and sensitivity during commissioning and troubleshooting. It integrates with standard RF measurement and transmission chains via BNC and DB9 control interfaces.

Condition: Used
This WV Communications 70-01FM-CH FM Modulation Sensitivity Adjust has been inspected and is in good used condition. The enclosure is clean with only minor surface wear typical of bench use. Front panel LEDs and the sensitivity adjust trim knob are intact and undamaged. Rear-panel BNC connectors, DB9, IEC AC inlet, and the fuse holder all appear in good shape with no bent pins or connector damage visible. Please view our photo set and contact us if you have any questions.
