The Bird 4410-2 is a plug-in element designed for use with Bird 4410A and 4412A Thruline® RF wattmeters. This element is engineered to measure forward and reflected power in 50-ohm RF coaxial transmission lines, suitable for Continuous Wave (CW) unmodulated or Frequency Modulation (FM) signals. The Bird 4410-2 operates within a specific frequency range and offers multiple selectable power ranges, contributing to the versatility of the associated wattmeter for various RF power measurement applications.
### Technical Specifications
* **Product Type:** RF Power Measurement Plug-In Element
* **Manufacturer:** Bird Electronic Corporation
* **Model:** 4410-2
* **Compatibility:** Designed for Bird 4410A and 4412A Thruline® Wattmeters
* **Frequency Range:** 0.45 MHz – 2.5 MHz (Some sources list 200 KHz – 2.3 GHz for other elements in the 4410 series, but the 4410-2 specifically is cited as 0.45-2.5 MHz)
* **Power Ranges:** Offers seven selectable power ranges. Specific ranges include:
* 0-10 W
* 0-30 W
* 0-100 W
* 0-300 W
* 0-1000 W
* 0-3000 W
* 0-10,000 W
* (Note: Power ranges are often expressed as full-scale values which are determined by the wattmeter’s range switch setting multiplied by the element’s factor number)
### Electrical Characteristics
* **Impedance:** 50 ohms nominal
* **Insertion VSWR:** Less than 1.05:1 up to 1000 MHz when used in 50-ohm applications with N-type connectors.
### Physical Characteristics
* **Design:** Cylindrical shaped plug-in element
* **Construction:** Silver-plated brass RF line section
* **Connectors:** Compatible with Bird Quick-Change (QC) type RF connectors. The associated wattmeter is normally supplied with Female N type connectors.
### Compatibility
* **Wattmeters:** Specifically designed for and compatible with the Bird 4410A and 4412A Thruline® RF Wattmeters.
* **Transmission Lines:** Intended for use in 50-ohm nominal impedance coaxial transmission lines. Using cables with other than 50 ohms impedance may result in inaccuracies.
### Usage and Performance
* **Measurement Type:** Measures forward and reflected power in RF transmission systems.
* **Signal Type:** Intended for CW unmodulated or FM signals only.
* **Accuracy:** Elements are calibrated in accordance with meticulous Bird calibration procedures, supported by a history of mean deviation values to assure adherence to specifications.
* **Dynamic Range:** Associated wattmeters offer wide-range accuracy over a 37 dB dynamic range.
* **Over-ranging:** The wattmeter can handle over-ranging up to 120% of the element’s power rating, depending on connector type.
* **Field Interchangeability:** Designed for field interchangeability with equipment purchased over the years.
* **Operation:** The plug-in element is inserted into the line section socket of the wattmeter and rotated against a stop. A catch ensures proper alignment and contact.
