Installation / Setup
The source does not provide specific information about installation or setup highlights, such as wiring, clearances, calibration, or prerequisites.
Operation
The operation and basic usage steps for the ROHDE & SCHWARZ AKTIVDEMODULATOR SWOB5-Z4 are detailed in sections 2.5 and 2.6 of the SWOB 5 description. The HF control output allows for the connection of a triggerable frequency counter, as mentioned in section 2.2.4 of the SWOB 5 description. When a converting measurement object (e.g., FS-Tuner) is wobbled, frequency measurements can be performed directly in the IF position using the variable brightness marker of the SWOB 5. The option “IF-Markers” allows for the generation of line or pulse markers in the IF position (between 1 MHz and 150 MHz). To do this, the control output of the active demodulator should be connected to the external marker input.
