Dynamic accuracy curve

Hi,

  The followed picture is in kesight free software uncertainty caculator, from my point of view it should only be one curve to describe the receiver's dynamic accuracy, which the x-axis is the input signal to the receiver, for example -10dBm is the actual signal, the corresponding y is the accuracy which is 0.1dB, so this means the receiver's measured data is -10dBm±0.1dB.  However why there are four curves (-10dBm at 1GHz, -20dBm at 1GHz……what are these dBm mean?)?

  And can I measure this kind of Dynamic accuracy mag/pha curve in my own E8363B?

 

Best Regards
