Which Standards Should I Use?
For broadband applications, shorts or opens work equally well
Choose the most convenient standard (often an open) –
this is a key benefit of Automatic Port Extensions!
Will using both an open and a short improve accuracy?
• Using two standards makes little difference for broadband applications, as
many ripples occur and calculated loss is the same for open or short
• Using two standards improves accuracy
for narrowband applications, where a full
ripple cycle does not occur
Broadband
Calculated loss is basically
same for open or short
