High noise immunity and immunity to interference are patented features of the Site Master S331 D, which allows measurements to be made on nodes with a large number of radiation sources. The PC data processing software allows you to monitor the various changes that occur in the system with the generation of relevant documentation.

The Site Master S331D is suitable for personnel of all skill levels involved in the installation, commissioning, troubleshooting and routine maintenance of any modern wireless transmission system including: VHF, broadband, cellular, PCX/GSM, 3G cellular systems , wireless LANs, etc.


Measurement of Return Loss Ratio and Standing Wave Ratio ( SWR )

To ensure that the system under test meets the specified performance, it is very important to measure the Return Loss Ratio or VSWR (VSWR). The Anritsu Site Master S331D allows you to accurately perform these measurements by easily switching from one mode to another. In this case, there is no need to climb a cell tower - measurements can be taken from the ground.


Cable loss measurement

By measuring cable loss, you can determine the level of signal attenuation in the feeder path caused by the presence of the cable. Cable loss measurement can be carried out before commissioning, when both ends of the cable are available, and directly during operation, when only one end of the cable is available. Anritsu Site Master S331D automatically calculates and displays the wastage rate. This eliminates the need to do any manual calculations.


Determination of distance to damage

Although the measurement of the return loss coefficient provides information about the level of signal reflection, it does not allow determining the exact location of damage in the AFU path. The Anritsu SiteMaster S331D analyzer allows you to accurately determine the distance to the location of damage or abnormal behavior, as it shows both the amplitude of the reflected signal and the distance to the places of reflection on the graph.


InstaCal Quick Calibration Module

The InstaCal Quick Calibration Module allows you to accurately calibrate your Anritsu SiteMaster S331D analyzer in half the time of using separate Open - Short - 50 ohm loads. When using InstaCal, it is enough to connect this module to the S331D only once and the calibration will be performed automatically.


Power Monitor (Option 5 for S331D and S332D)

For power measurements over a wide frequency range, use the Anritsu 560 and 5400 series detectors. These detectors are excellent for measuring the 18 GHz T1/E1 base station channel. The measurement range is -50 to +16 dBm and the indication range is -80 to +80 dBm. There are several types of detectors for different frequency ranges.


Power Meter (Option 29 for S331D and S332D)

The Power Meter (Option 29) is used to make accurate transmitter power measurements from 4.5 MHz to 3 GHz, allowing base station tuning to avoid weak signal patches as well as excessive signal strength. It does not require any additional external detectors.


GPS receiver (option 31 for S331D and S332D)

The built-in GPS receiver provides position information (latitude, longitude and altitude) as well as global time (UT). The Anritsu Site Master S331D analyzer can add location data to the measurement result so that you can later check the measurement points. This option comes with a magnetic antenna with a 5 meter cable. Using a magnet, the antenna can be attached to the roof of a car or in any other convenient place.


T1/E1 Analyzer (Option 50)

This option allows you to add the Anritsu Site Master S331D analyzer with the ability to measure and analyze the T1 / E1 protocol, thereby expanding the diagnostic capabilities of the device. With option 50, the Site Master S331D analyzer can display T1/E1 data as a bar graph and accumulate measurements for 2 days. Also, the Site Master S331D analyzer gets the ability to measure the signal voltage (Vpp) and display it on the display in dBdsx units.


Handheld Software Tools

The Anritsu Site Master S331D analyzer contains many built-in calculation and documentation functions. To perform additional processing on a computer, use the Handheld Software Tools, which is included as standard with the instrument. With this software, the measurement results made by the Anritsu Site Master S331D analyzer can be transferred to a computer, examined and stored.
