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.
插入损耗、NEXT和回波损耗的测量被称为“扫频”测量，这意味着测量所选测试标准的最小和最大频率之间的某些点。不用说，如果你在1Mhz到1000Mhz之间只测量100个点-他就会测试速度非常快，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.
