Using Tips for balanced VNA Test Cables(3)

There are many difficulties to overcome in generating a true differential signal: First, a 180-degree phase shift must be achieved between the two internal sources, and this phase difference must be accurately controlled to ensure the quality of the differential signal. In addition, in the measurement and calibration reference plane, this phase difference is still valid. The loss, phase and other characteristics of the cable used in the test will vary, which brings many difficulties to accurate measurement. VNA test equipment needs to use VNA Test Cable, contact me to get quotation. Whatsapp/Skype: +86 18028785424

The calibration method of the instrument is consistent with the standard “thru-open-short-match or SOLT” calibration method. Even if the test cable is asymmetric (for example, different lengths) or on-chip testing, this calibration method is also applicable. The instrument can also generate signals with a phase difference of 0 degrees (in-phase) for common mode testing. In the previous instruments, the phase drift with time and temperature is a serious problem. Here, the internal source adopts a special algorithm and control circuit to continuously check and correct the phase difference of the internal source to ensure the strict amplitude and phase relationship of the differential signal.
