The Coaxial Dynamics 7601 Relative Field Strength Meter is a specialized instrument designed for measuring the relative strengths of radiating fields from transmitting antenna systems. Here are the key features, options, and specifications:
Features:
- Superior Sensitivity:
- Provides high sensitivity for accurate measurements.
- Broadband Operation:
- Usable over a wide frequency range from 1 to 3000 MHz.
- Adjustable Gain Control:
- Allows users to adjust the gain control for different measurement scenarios.
- Internal Battery Test Circuit:
- Includes a built-in circuit for testing the internal 9-volt alkaline transistor battery.
- Detachable Antenna:
- Features a detachable antenna for flexibility, with the option to choose between a Rubber Duck style antenna (supplied) and an optional telescoping antenna for improved sensitivity.
- Large Easy-to-Read Meter:
- The meter is large and easy to read, visible from many feet away.
- Two Year Limited Warranty:
- Assures users of the quality and dependability of the Model 7601.
Available Options:
- Telescoping Antenna (Model 7600-008):
- Provides improved sensitivity, with a range of 4 to 19 inches.
- Field Strength Element (Model 7610):
- Designed for use in Model 81000-A or equivalent.
Specifications:
- Frequency Range:
- 1 to 3000 MHz
- Typical Sensitivity:
- 1 Watt CW source from a unity gain antenna at 150 MHz will cause full-scale deflection at 10 feet with the gain control set at maximum.
- Battery:
- One 9-volt alkaline transistor battery (supplied)
- Weight:
- 8 oz (.23 kg)
- Dimensions:
- 3.13″ x 5.0″ x 2.13″ (7.95 x 12.7 x 5.41 cm) without antenna attached
- Case Finish:
- Textured Blue and Tan Polyurethane Enamel
Note:
- The Model 7601 can be connected directly to an existing base or mobile antenna for added flexibility.
This instrument is suitable for tasks such as measuring RF field strengths, making relative RF power measurements, and adjusting transceivers and antennas. The inclusion of a detachable antenna and options like the telescoping antenna enhance its adaptability and sensitivity for various use cases.
