VSWR Null value

Hello, dear.
DSP VSWR query standing wave value is the RF module using the current operating power to start the automatic standing wave test results, while STR VSWRTEST is based on a single tone to start the standing wave test at maximum power, and the two test accuracy is different, so the results of the two will be different.

Hi,

Probably, the 'dsp vswr' command was not ready to deliver the measured results in the beginning.
Because, a VSWR is a ratio (can not be 0 ) - ideally, theoretically it is 1 (one).

And you want it to be close to 1... with a high VSWR value, it is risky to transmit with power: it may damage the Tx electronics/hardware.
