The Anritsu VNA Master MS202xB models are capable of approximately four hours, and the MS203xB models are capable of approximately three hours, of continuous operation from a fully charged, field‑replaceable battery (refer to Battery Replacement).
The VNA Master can also be operated from an external power source (which also simultaneously charges the battery). This can be achieved with either the Anritsu AC‑DC Adapter or the Automotive Cigarette Lighter Adapter. Both items are included with the VNA Master.
Caution
When using the Automotive Cigarette Lighter 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.
To turn on the VNA Master, press the green On/Off button on the front panel (Figure: VNA Master Overview). The VNA Master takes approximately sixty seconds to complete power warm‑up and to load the application software. At the completion of this process, the instrument is ready for use.
