The DC-Blocker must be used if you want to measure active powered antennas like GPS or satellite dishes. It prevents damage to the input of RF analyzers by blocking up to 18 VDC. Simply connect the DC-Blocker to the RF-input of your SPECTRAN and you can measure directly on GPS, satellite antennas or even DSL/ISDN etc., lines.
![calibration-resistor](https://aaroniausa.wpengine.com/wp-content/uploads/2015/08/calibration-resistor-300x300.jpg)
For the Spectran V4 (SMA), this calibration resistor is necessary to calibrate the noise-floor (Firmware BETA26 up). The new noise floor calibration feature can be activated at any time with the new “CalRun” function in the “Setup” menu. You only need to connect the calibration resistor to the rf-input of the SPECTRAN V4.
