The Anritsu VNA Master is capable of greater than two hours of continuous operation from a fully charged, field‑replaceable battery (refer to Battery Replacement in General Information). The VNA Master can also be operated from a 12 VDC source (which also simultaneously charges the battery). This can be achieved with either the Anritsu AC‑DC Adapter or 12 VDC Automotive Adapter. Both items are included as standard accessories (refer to the Standard and Optional Accessories in the Technical Data Sheet for your instrument, as listed in Supplemental Documentation).
Caution
When using the Automotive 12 VDC Adapter,, always verify that the supply is rated for a minimum of 60 Watts at 12 VDC, and that the socket is clear of any dirt or debris. If the adapter plug becomes hot to the touch during operation, discontinue use immediately.
The VNA Master requires approximately thirty-five seconds to complete the power‑on cycle and load the application software. At the completion of this process, the instrument is ready to use.
The VNA Master performs a self test during each power-on cycle. If the self test fails, then refer to Self Test or Application Self Test Error Messages in Error Messages. For maximum accuracy, letting the instrument warm up for approximately 15 minutes is a good practice before performing a calibration.
