There is no way to retrieve the traces once you have deleted them. It's always a good practice to download the traces from the Site Master to a laptop before leaving the site.
The FCC regulates how much output power of any given transmitter. Since this is a fixed quantity, the system designers are forced to squeeze out every bit of performance out of the entire system.
The Site Master goes into a power saving mode after 10 minutes of inactivity. Just press the RUN/HOLD button and the unit will begin sweeping again.
You may calibrate the Site Master with one precision load and make measurements with another precision load. Type "N" loads are specified to be better than 42 dB return loss, and 7/16 Din loads are specified to 45 dB. You can never make a measurement better than the quality of the calibration components being used. This is true for ALL test equipment.
The Code Loader program allows you to keep the installed firmware version of your Site Master current to the current version being shipped. In other words if you had for example, 6 units and they all had different versions, as seen when you turn the box on, then you could make them all current with the latest version.
This is the Site Master temperature icon. It indicates that the internal temperature of your unit has changed enough to make the calibration invalid. When it appears, you should re-calibrate your instrument. You can check the temperature range of your most recent cal by pressing .sys.status.
Files saved with an older version of software tools such as 6.40 can be read and manipulated with version 6.41. Files which were saved with the new 6.41 version can not be read and manipulated with an older version such as 6.40.
Marker and trace data are displayed properly in German and French Regional Settings when "German(Swiss)" and "French(Swiss)" regional selections are made. To select the operational German or French Regional Settings, do the following : Go to Start up Menu - Settings - Control Panel - Regional Settings Select "German(Swiss)" Regional Settings for German users or "French(Swiss)" Regional Settings for French users.
There might be a calibration problem. Have you performed an open/short/load calibration? Check the calibration kit for mechanical damage.
Site Master defaults to having a minimum contrast which often appears blank. Adjust the contrast with the up/down arrow keys until the display appears.
Installation of Windows 2000, Service Pack #1 is required. The Service Pack #1 can be found at: "http://www.microsoft.com/windows2000/downloads/servicepacks">http://www.microsoft.com/windows2000/downloads/servicepacks
Your InstaCal module can be used on any S11xC, S33xC, or later models. InstaCal will not work on the older "B" models or on the S251C.

The cable is a RS232 with 9-pin female connectors on both sides and needs to be a null-modem cable. In an emergency, purchase the following part numbers from Radio Shack. 26-152 and 26-264.
The waveguide calibration uses a 1/8 wavelength offset short, a 3/8 wavelength offset short and a precision waveguide load for calibration. For coax calibration the open and short both causes high reflections back to the Site Master but an open on a waveguide causes minimal reflections to occur although they are about twice as much as the load. The 1/8 and 3/8 offset shorts are used to set the 0 (zero) reference of the Site Master just like the Open/Short for coaxial calibrations.
Anritsu has a USB-to-Serial adapter, part number 551-1691 or customer can order the Earthmate USB Power Adapter directly from DeLORME at "http://www.delorme.com">www.delorme.com.
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.
This is caused by opening a plot that has been saved by a higher version of the Site Master software, i.e. you can not open a plot that has been saved by v6.41in v6.31 or lower. The person trying to view the plot must upgrade their version of the software. NOTE: if, after opening the plot and seeing the problem, the user saves the plot it will corrupt it and will exhibit the same problem even when opened in the original version of software. Just opening the plot will not corrupt it.
All model "C" units have the external connector for power monitoring, but power monitor is an option (#5) and must be installed at the time of ordering or the unit must be returned for an upgrade. You will also need a power detector, which is an accessory. Check your users guide for a list of Anritsu Power detectors available for your unit.
Connectors! Improperly assembled or installed connectors cause a significant number of cell site problems. Many do not exhibit any problems at the time of commissioning, but much later as the elements take their toll on the system. This can often be found early during a maintenance period. By making similar DTF measurements at both the installation and the maintenance, changes in connector performance can easily be seen. Other sources of cell site problems include crimped, dented, crushed or punctured cables. Check your cable vendor's specifications for installation to be sure you exercise proper handling.
