Measurements such as Insertion Loss, NEXT and Return Loss are referred to as “swept frequency” measurements, meaning that certain points between the minimum and maximum frequency of the selected test standard are measured. It goes with out saying that if you only measure 100 points between 1 MHz and 1,000 MHz – it will make for a very quick test, but fail to provide the desired resolution.
插入損耗、NEXT和回波損耗的測量被稱為“掃頻”測量，這意味著測量所選測試標準的最小和最大頻率之間的某些點。不用說，如果你在1Mhz到1000Mhz之間只測量100個點-他就會測試速度非?？?，但是不能提供所需的分辨率。
So the field testing standards ANSI/TIA-1152 and IEC 61935-1 define the minimum frequency steps (resolution) for the test equipment vendors.
ANSI/TIA-1152
IEC 61935-1 Ed.4
The DSX2-8000、DSX2-5000 provides better resolution than the minimum required for IEC 61935-1 Ed.4. It is worth investigating what resolution your vendor is using.
