The SMK-3000 Kit contains precision, high power standards that are used to calibrate RF radios, wattmeters, directional couplers and other high-power RF test equipment in the field or metrology lab. Unlike other calibration solutions, the SMK-3000 calibration kit reduces the cost of ownership and provide a much faster time-tocalibration with lab precision and accuracy you’ve come to expect from Bird.
Covering a frequency range of 1 to 1000 MHz, the in-line calibration kits enable users to calibrate +/- 3% accuracy in just minutes.
Included in the SMK-3000 kit is the Model 4421A Multifunction Power Meter. This intuitive display unit clearly identifies the Forward and Reflected power measurements within the RF path. In addition, return loss readings can also be shown to provide additional insight into the RF system being monitored.
