Calibration
The Site Master is a field portable unit operating in the rigors of the test environment. An
NOTES:
For best calibration
For best results, use a phase stable Test Port Extension Cable (see Optional Accessories). If you use a typical laboratory cable to extend the Site Master test port to the device under test, cable bending subsequent to the OSL or OSLT calibration will cause uncompensated phase reflections inside the cable. Thus, cables which are NOT phase stable may cause measurement errors that are more pronounced as the test frequency increases.
For optimum calibration, Anritsu recommends using precision calibration components.
Annual Verification
Anritsu recommends an annual calibration and performance verification of the Site Master and the OSL calibration components by local Anritsu service centers. Anritsu service cen- ters are listed in Table
