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
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
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.
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.
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.
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.
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 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.
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.
With the OSL calibration, you have to calibrate each time you change the frequency range. With the FlexCal, you can change the frequency range and you don't have to perform another calibration. FlexCal is great for troubleshooting purposes. The accuracy can be affected if your span is really narrow so for optimum accuracy, it is recommended to use the OSL calibration.
No external detector is required for this option. The spectrum analyzer board and detection circuit is used to provide the user with frequency selective power measurements.
