The load attached to the H4 has been re-matched to perform better at
higher frequencies. The 49.9 ohm load used earlier performed quite badly
above 2GHz, but the new and improved load can get S11 below -30dB at 6GHz.
For measurements that require higher frequencies, the new load better. For
UHF measurement, I suggest you use the load included with H4 for
calibration.
This is the test report provided by Kurt after I provided H4 OSL accessories and 6GHz VNA to Kurt. It can be seen that the effects of OSL accessories within 6GHz are satisfactory.
The test information provided in the attachment, OSL is the same as H4, FF thru has been redesigned and will be provided with our future products.
