The voltage level on bias tee Option 10A is set at 15V. The voltage level on bias tee Option 10B is switchable between 15V (high voltage) and 12V (low voltage). The current level on bias tee Option 10A is 460 mA Surge/244mA steady state. The current level on bias tee Option 10B is switchable between 1A surge/650mA steady state (high current) and 460mA surge/244mA steady state (low current).
No, the sitemaster "C" models and below will not save any power monitor (option 5) measurements. You can use this function on the "D" model sitemasters i.e. S311D/S312D, S331D/S332D, S810D/S820D, and MS2711D.
On the S331D delete the displays that are showing the weird characters with lines missing. Delete all that are not normal looking and try the download after the corrupt displays are deleted.
You need a 2-port measurement so you can send out a signal from a transmit antenna and monitor the signal coming in at the receive antenna. You can either use the S251C with its insertion loss mode or you can use the Site Master and Cell Master with its Transmission Measurement modes. The benefit of using the S251C is that the nominal output power is higher or about +6 dBm vs. about -10 dBm with Option 21. The further apart the antennas are, the lower the signal will be in the Rx antenna and for optimum dynamic range it is helpful to use max power level. When you make the measurement, you start out calibrating the instrument with a through cal (Option 21) or a 1-path 2-port cal (S251C insertion loss mode). When you connect a cable from the RF out to the RF in port of the Site Master, you should see a flat signal. When you then connect RF Out to a Tx antenna and RF in to a Rx antenna, you are essentially looking at how much power is going into the Rx antenna or the acutal isolation between the two. Depending on the system and the setup, the values will vary and you'll need to check with the system engineer to see what is recommended for your system.
Something is violating our specifications (typically over-current), causing the bias-tee to shut off. After a second or so, the bias tee will try to come back on. If the violation still exists, it will shut off again, and continue the cycle until the violation is removed. The clicking is the relay changing states.
Maximum input power is, 1.0 W (0Â° C - 50Â° C)
The short answer is yes. The return loss of a cable & antenna system will be different if you are making a return loss measurement of a 15 dB antenna with two different cables. The return loss of the system is proportional to 2*CL (Cable Loss). System designers takes this into consideration when determining the specifications.
Before capturing Trace, go to Settings on Handheld Software Tools then Default Plot Setting and then select Per Site Master under Plot Scaling.
Resolution can not be changed after the sweep is saved.
125 cables for current platform and 49 cables for old platform. Current platform: MT2812B/S331D/S332D with firmware version of V3.00 or higher. Any S810D/S820D, regardless of firmware version. Old Platform: All other models/firmware versions other than listed above.
SC5237: DC to 4.0 GHz, 16.4 to 16.8 ohm 6dB +/- 0.25 dB
SC5270: DC to 4.0 GHz, 40.66 to 41.1 ohm 20dB +/- 1.5 dB
In HHST go to File>Database>Select the data base you want to open. This will open a window called Site Master Database showing pointing to your database. Display records 1 at a time or display all depending on the version of HHST you are using. Save each record as a .DAT trace file one at a time.
The return loss specification is 40dB up to 2.5GHz and 38dB up to 4GHz.
All the Site Master, Cell Master and Spectrum Master Products (excluding MS2721A) include an RS-232 serial port. Most of the new lap top computers available in today's market do not feature an RS-232 serial port but feature a Universal Serial Bus (USB) port instead. To address this issue, a USB to Serial adapter can be used. It is important to note that the adapter can not be used to communicate with the Handheld Code Loader software and can only be used to communicate with the Anritsu Handheld Software Tools (Version 6.49 or above) to download and upload traces. Most of the USB to Serial adapters available today in the market will work, provided the computer uses an operating system that supports USB interfaces and that Handheld Software Tools (Version 6.49 or above) is used. The following USB to Serial adapters have been evaluated by Anritsu and have been confirmed to work properly: . HP (5184-2172) . Belkin (F5U103) . Xircom (PGSDB9) . Keyspan (USA-19QW) . Delorme (DEL00331) . Tripp Lite (U209-000-R) . Anritsu (551-1691) If an earlier version of Handheld Software Tools is being used, only the Anritsu supplied adapter will work.
The frequency response and isolation of the Polyphaser should be better than the Antenna. The Polyphaser would be transparent to the antenna sweeps response.
To measure power greater than +20 dBm an external attenuator is required. The display range of the instrument is -80 dBm to +80 dBm so therefore you can measure up to +80 dBm with a 60 dB external attenuator.
Using HHST (handheld software tools) select FILE -> Database. A window will pop up called "Select a Database" and from there you can either create a new database or open an existing one. Click on "Open a Database" and then click on "OK". In the window that pops up navigate to the location where the database is stored on your hard drive. Select it and then click "Open". You may get an error Number 5 and if so hit "OK" to ignore this error message. In the HHST screen you should see the "Site Master Database" window showing the traces saved in the database just opened. Note that you may need to click on the "Site Master Database" icon in the Windows Taskbar before the window is displayed.
No, for sitemaster "C" Models and below, this function is not supported. You can use this function on the "D" Model sitemasters. (S311D/S312D, S331D/S332D, S810D/S820D, MS2711D).
The connector marked RF Out / Reflection is the only port that requires OSL calibration for Return Loss or / SWR measurements. Some Models like the S251C can make Insertion Gain or Insertion Loss measurements and the second port is included in an OSLIT (Open, Short, Load, Isolation, Through) calibration. Refer to the Users Guide for additional details.
Based on the resolution chosen, there are a discrete number of data points that are created in the graph. The markers can fall only on one of these discrete points in the graph. To find out how the points are spaced apart from F1: (F2-F1)/# of points.
