SWR Accuracy

[wa9zvf]

Most traditional SWR meters dating back to the '60s and 70s have an inherent inaccuracy with swrs near 1 to 1 due to a "diode drop" in the bridge.  Does the AIM series of VNAs have any accuracy issues with swrs near 1 to 1?

Hi Ray,
The AIM is linear over the whole impedance range so it is very accurate when the SWR is around 1:1
