Bird 4421-107 RF Wattmeter

Bird 4421-107 RF Wattmeter Technical Specifications

• Power Measurement Range: Wide capacity from 100 mW to 10 kW (full scale) depending on the attached sensor type.
• Frequency Measurement Range: Wide RF signal frequency support from 100 kHz to 2.5 GHz depending on the selected intelligent sensor series (4020, 4027A, 4027F, 4028 series).
• Accuracy Ratio: ±1% full scale accuracy thanks to the automatic frequency compensation scheme that eliminates errors from the directed sensor's frequency response.
• Measurement Repeatability: Excellent repeatability at a level of 0.1% that provides high consistency and prevents deviations in laboratory environments. <
• Wide Dynamic Range: Ability to maintain all specified sensitivity and accuracy values without calibration over a wide dynamic range of 35 dB.
• Measurement Parameters and Functions: Forward power (Forward - W or dBm), reflected power (Reflected - W or dBm), VSWR (1.0 - 199.9) and Return Loss (dB).
• Data Tracking Capability: Ability to track and store minimum (MIN) and maximum (MAX) values of any RF parameter displayed on the screen.
• Range Selection (Ranging): Manual range selection or automatic range (autoranging) mode that works based on signal power, according to user preference.
• Display and Screen Type: 3½-digit digital LCD screen that can be turned on and off as desired, including mode, measurement units, battery status, programming status, and trend indicators with backlight.
• Digital Connection and Interfaces: Standard IEEE-488 (GPIB) and RS-232 serial interface modules located at the back of the device for automation systems, computer integration, and remote control.
• Operating Power: Dual power supply support with both AC mains electricity and built-in rechargeable battery for portable field tests.
• Size and Weight Information: Compact metal case design suitable for benchtop and mobile use with dimensions of 114 mm x 165 mm x 312 mm and a net body weight of approximately 5 kg (11 lbs).
