Presently the Site Master does not support P25 demod.
HHST is compatible with VISTA 32 bit operating systems but not with VISTA 64 bit OS. Also per Delorme their USB to serial adapter is not compatible with VISTA 32 or 64.
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.
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.
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 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.
Option 5 requires a external detector. The measurement range is -30 to +16dbm. Option 29 does not require a external detector and has a measurement range of -80 to +20dbm.
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.
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
The InstaCal has a specified directivity of 38 dB for frequencies below 3.5 GHz while the regular calibration tee provides >42 dB of directivity. The directivity is many times the largest contributor to measurement uncertainty and this difference between the two calibration techniques will affect the uncertainty. The difference in performance will be more prevalent the closer to the directivity you are. For instance, if you are making a return loss measurement of an antenna and the overall system return loss is 10 dB, the difference in performance will be less than 0.1 dB. If the overall return loss is 20 dB, then the OSLN50-1 tee will be at least 0.35 dB better than the ICN50 Instacal. In general, it is recommended to use the InstaCal when you are looking for a fast way to make the cal. If superior accuracy is of important, then the precision calibration tee is the best way to go.
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.
No, the 6GHz Frequency Extension only applies for the Cable and Antenna measurements that the S332D can make.
This has to do with the COM settings. For signal standards, it is assuming that you are using COM1 and if you are not, it will be challenging. To change this, please see below: Go to Settings -> Control Panel -> System -> Device Manager -> Ports -> double click on USB to RS232 -> port settings -> advanced -> change COM number to 1 In HHST: Settings -> Communication -> COM1
Maximum input power is, 1.0 W (0° C - 50° 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.
The maximum cable loss one should expect to have an accurate measurement is 10 dB or less. For measurements that exceed 10 dB, the uncertainty increases significantly. The 2 port cable loss measurement technique should be used in these cases.
The battery designed to work with the Site Masters has circuitry that communicates with the mother board. If you bought an off the shelf battery it will not have this circuitry and will display this message. If it is a battery was bought from Anritsu then you may need to contact an Anritsu service center.
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.
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.
