The Anritsu S331B Site Master is a hand held SWR/RL (standing wave ratio/return loss), and Distance-To-Fault (DTF) measurement instrument that includes a built-in synthesized signal source. It includes a keypad to enter data and a liquid crystal display (LCD) to provide graphic indications of SWR or RL over the selected frequency range and selected distance. The S331B SiteMaster is capable of up to 2.5 hours of continuous operation from a fully charged field-replaceable battery and can be operated from a 12.5 dc source. The Site Master is designed for measuring SWR, return loss, or cable insertion loss and locating faulty RF components in antenna systems. Specifications
Frequency Range: 25 to 3300 MHz. Frequency Accuracy (CW Mode): 75 parts per million. Frequency Resolution: 10 kHz. Measurement Range: SWR 1.00 to 65.00, Resolution: 0.01 dB. Return Loss Range: 0.0 to 54.00 dB, Resolution: 0.01 dB. Distance-To-Fault (DTF) Range (in meters):0 to (Resolution x dp). Maximum Input (Damage Level) +22 dBm. Cable Insertion Loss Range: 0.00 to 54.00 dB, Resolution: 0.01 dB.
Option 5, Add RF Wattmeter Power Monitor.
