Display VSWR (DSP VSWR)


Function

Use this command to display the WRFU/RRU VSWR (Voltage Standing Wave Ratio).

Note

• You may use this command only if the specified WRFU/RRU runsnormally. This command is not supported by PRRU and MRXU.
• When the TX power is relatively low (14.5 dB lower than the maximum TX power), the S/N of the feedback signal passing through the feedbackchannel is relatively low, which leads to the inaccuracy of the VSWR calculation. In this scenario, the VSWR alarm is not reported if the VSWR is detected relatively high. When the TX power isrelatively high, the S/N of the feedback signal passing through the feedback channel is relatively high and the VSWR calculation is accurate. In this scenario, the VSWR alarm is reported if the VSWR isdetected relatively high. Therefore, after this command is executed, if the detected VSWR at the antenna port is relatively high and no VSWR alarm is report, you can infer that this is a normal case.Parameter
