Anyone who needs to make basic cable/antenna and power measurements will benefit from the new S331L Site Master. The simple no option configuration and high value pricing make the S331L ideal for tower contractors and can be easily provisioned by stocking distributors and rental companies alike. For contractors who don't have time to look for nearby power sources, the S331L will last an entire workday on a single battery charge, meaning you can be a lot more productive with your day. Not only does the Site Master S331L run longer, it also has a lot more memory internally so you don't have to worry about running out of space for all of those extra measurements you just made. Your CAPEX affects your profitability, and your stability. The new S331L is the best value in a handheld cable and antenna analyzer period. You can get more done with minimal negative impact on.

At under 2.0kg (4.4lbs) including battery, it’s effortless to carry whether you are on level ground, climbing a large tower, or heading through a roof hatch, your Site Master easily goes along with you.

Beginning of a traditional workday
With the battery fully charged, you’re ready for a full workday of measurements. This is the longest lasting Site Master operation time we’ve ever offered in a handheld cable and antenna analyzer. You won’t need to look for outlets and drag power supplies with you from site to site anymore. Now you can focus on what matters, making measurements and getting the job completed.

Starting out fully charged at 9:00 am

8 hours later, still running and still measuring
After 8 continuous hours of battery operation, the Site Master S331L is still measuring. We understand that 8 continuous hours is an unlikely scenario, but we are proud of the S331L’s extended battery life and feel it deserves to be recognized.
The S331L also has intelligent power saving features to extend the operating time further, providing as much as 10 hours of operation.
Features like sleep mode with instant on, handy for travelling between sites, and auto-display brightness that will reduce the screen backlight automatically if the instrument has not been accessed for some time. One touch of the screen, keypad, or twiddle-knob will automatically restore brightness levels.

Markers & Limits
Using the stylus pen (provided) or fingers, users can drag or place markers and limits anywhere on the measurement screen.
Values can also be entered with number keys, or by turning the rotary knob. Several easy and convenient ways to place markers
and limits where you want them, or use the auto search max/min peak functions if you prefer.

Dragging markers and limits with fingers is really easy and convenient.

Convenient Shortcuts
User defined shortcuts can be created for one-button access to commonly used functions. (Advanced Mode only)

Internal Power Meter
The Site Master S331L includes a convenient, easy to use, built in power meter.
Setting the transmitter output power of a base station properly is critical to the overall operation of wireless networks. A very small change in power levels can create a large change in actual coverage area, resulting in dropped calls and low data rates.
