The S331D when upgraded to Version 5.23 firmware or later has the internal capability to make Optical Distance To Fault measurements. An external Optical Distance to Fault Module is also needed to make the Optical DTF measurement. This part number is ODTF-1.
If you have a wireless device enabled on your PC or laptop this can interrupt the serial communication. Go to Network connections and verify your Wireless Network connection type LAN or high speed internet is disabled. Even it says disconnected you should disabled it. This has been known to help in cases where everything is set up properly. Wireless devices such as Palm Pilots can cause this also so disable all wireless devices that you use.
No. The majority of TMAS for cellular antennas will block the RF signal from the Site Master so the sweeping signal will only go as far as the TMAS and not reach the antenna.
Yes but you need to be very careful that the RF from another Source is not going to exceed the 20 dBm max on the RF port. Power in excess of 20 dBm can result in damage to the unit.
No. If someone sends you a .csv file MST cannot be used to convert it back to a .vna file to be opened in MST.
The calibration goes out when the temperature has deviated more than 15 degrees from the temperature at which the calibration was performed. This information is also available in the instrument. Simply press SYS and then Status after performing the calibration. The instrument will show the current temperature and then Cal Temp Range will show up as Current Temperature +/- 15C.
Try opening the plots one by one. You should run into one that will not open and this plot is most likely corrupted. Unfortunately, when this is the case, there in nothing that can be done. Erase the plot and try your download again.
Traditionally, measuring the insertion loss of an installed coaxial cable is a one-port reflection measurement since it is virtually impossible to connect both ends of the cable to test equipment. The measurement is made by placing a short on one end of the cable and measuring the return loss at the other end. The desired value, cable loss, is return loss divided by two, since the signal travels through the cable in both directions.
Windowing will reduce the lobes depending upon their severity. It is similar to an averaging or smoothing technique. There are four windowing options available: Rectangular windowing – Normal mode of operation. Nominal side lobe – Some smoothing Low Side Lobe – More smoothing Minimum side lobe – Maximum smoothing
Currently Anritsu does not but is working diligently to provide a solution.
The GPS coordinates delivered by the instruments are based on the WGS-84 methodology of determining position.
Yes. If you are testing the line with the antenna attached, there is a good chance that the Site Master could be damaged by ESD. This happens because ESD gets onto the center conductor through the antenna's elements. It is safe to test with a load or short because there is no path for the ESD to get onto the center conductor.
An integrator failure is typically caused by excessive RF power to the input of the Sitemaster. Different Sitemaster models have different damage levels that they can tolerate and newer models have improved immunity to overpower conditions. See the appropriate user manual for the damage level for your particular unit. One common way this overpower condition can be caused is by a high powered interfering carrier when testing with the antenna attached at a co-locate site. If the power level of the interference is too high it could cause damage to the Site Master. To find out if damage has occurred, disconnect the Site Master from the coax under test and if the integrator failure still occurs then there may be damage to the unit. To prevent this type of situation, check the power level on the antenna first using a power meter or power monitor (Options 29 or 5) to see if any power is present on the antenna before sweeping it.
This is a problem with the database operations. It is caused when more than 2 lines of information have been added into the Plot Description field even if the extra lines are blank. To fix this, select the Record then select Edit. Place the cursor at the end of the 2nd line of the Plot Description field. Left-click and hold down the mouse button and scroll down. The cursor will now be below the 2nd line. Press the Delete key on the keyboard to remove the extra lines. The cursor should now be at the end of the 2nd line. Either select another record or select Done. To prevent this from happening on the initial entry of Plot Descriptions, try to remember not to press the Enter key when done with the 2nd line entry.
If a battery is allowed to totally discharge, the smart-memory capability of the battery may be lost, resulting in incorrect battery capacity readings or loss of communication with the battery.
Each battery holder in the optional charger has an LED charging status indicator. The LED color changes as the battery is charged: Red indicates the battery is charging Green indicates the battery is fully charged Yellow indicates the battery is in a waiting state. A yellow light may occur because the battery became too warm during the charge cycle. In this case, the charger will allow the battery to cool off before continuing the charge. A yellow light may also indicate that the charger is alternating charge to each of the two batteries.

If a flashing LOW BATT indicator is accompanied by an audio beep at the end of each trace, the battery has approximately one minute of useable time remaining.
The NiMH battery will last longer and perform better if allowed to completely discharge before recharging. For maximum battery life, it is recommended that the NiMH battery be completely discharged and recharged once every three months.
The Code Loader can only be used to upgrade Site Master models that have the capability to upgrade the firmware through the serial port. The S331 uses an Eprom-based firmware which can only be upgraded by an Anritsu Service Center. The models that can not be upgraded with the Code Loader are: 110, 330, S110, S111, S330, S331, S330A with serial number range of 702xxx through 706xxx and S331A with serial number range of 702xxx through 706xxx.
