External Power
The external power connector (refer to item 6 in Figure: MS2035B Test Panel Connectors) is used to power the unit and for battery charging. Input is 12.5 VDC to 15 VDC at up to 4.0 A. The green flashing Power LED near the power switch indicates that the instrument has external power.
Warning
When using the AC‑DC Adapter, always use a three‑wire power cable that is connected to a three‑wire power line outlet. If power is supplied without grounding the equipment in this manner, then the user is at risk of receiving a severe or fatal electric shock.
USB Interface – Type A
The VNA Master has two Type A USB connectors (refer to item 7 in Figure: MS2035B Test Panel Connectors) that accept USB Flash Memory devices for storing measurements, setup data, and screen images.
MS2035B Connected to PC via USB Mini‑B
USB Interface – Mini‑B
The USB 2.0 Mini‑B connector (refer to item 4 in Figure: MS2035B Test Panel Connectors) can be used to connect the VNA Master directly to a PC, as shown in Figure: MS2035B Connected to PC via USB Mini‑B. The first time the VNA Master is connected to a PC, the normal USB device detection by the computer operating system will take place.
Note 
For proper detection, either Line Sweep Tools or Master Software Tools must be installed on the PC prior to connecting the VNA Master to the USB port.
LAN Connection (Option 411)
The RJ‑45 connector is used to connect the VNA Master to a local area network or directly to a PC with an Ethernet crossover cable. Integrated into this connector are two LEDs. The amber LED shows the presence of a 10 Mbit/s LAN connection when on, and a 100 Mbit/s LAN connection when off. The green LED flashes to show that LAN traffic is present. For more information on the LAN connection, Ethernet connection, and DHCP, refer to LAN and DHCP.
Headset Jack
The headset jack provides audio output from the built‑in AM/FM/SSB demodulator for testing and troubleshooting wireless communication systems. The jack accepts a 3.5 mm 2‑wire or 3‑wire miniature phone plug such as those commonly used with cellular telephones. (Refer to item 8 in Figure: MS2035B Test Panel Connectors.)
