Bird Vswr

Bird Vswr. I suggested that they make these measurements with a Bird 43 wattmeter with the appropriate plug-in. Read incident and reflected CW and FM power in watts or dBm.

This ratio can also be measured in dB and expressed as Return Loss. Wattmeters. VSWR is a measure of the reflected power on a transmission line.

The capability of single frequency readings and frequency sweeps allow for everything from pinpoint.

AND Simple and Standing wave ratio the reflected THRULINE latter to The In Fig. Bird 43 Thuline Wattmeter that provides forward and reverse power Directional power meters again use a directional coupler. Bird even has an application note VSWR Measurements Using In-Line Power Meters on how to do this. VSWR specs specifications are introduced along with formulas for mismatch loss and return loss in relationship to VSWR.
