3.1 Initialization
Connect the power supply of the ACT-5X and then turn on the exciter/translator via the power switch
located on the rear of the unit. The initialization process takes about 5 seconds to finish while the RF
output level gradually increases to the pre-set value.
The ACT-5X platform can operate in both Translator and Exciter modes. In Translator Mode, the unit
receives an RF signal (via the TUNER_IN rear panel connection) and feeds this to an internal tuner that
performs a demodulation at the specified receive frequency, followed by a modulation at the specified
transmit frequency. In Exciter Mode, the unit operates upon a TS signal (received via one of the ASI rear
panel BNC inputs, TS_IN_1 or TS_IN_2) and performs a modulation at the specified transmit frequency.
The first step after turning on the unit is to confirm the desired operating mode (Exciter or Translator)
according to your application. The “INPUT” setting located under the “SYSTEM” submenu should be set
to “TS” for exciter mode or “TUNER” for translator mode. Please see Table 6 below for details.
3.2 Query Mode
Query mode is a mode which displays parameters and status of the exciter/translator. There are three
pages in query mode. Press the "Right" or "Left" button to switch between different pages which are
