PTX30 UHT /S3 4. General Description The PTX30 is contained in a 19" 3U rack, internally assembled with modules mounted on a main chassis, all interconnected with connectors, allowing easy servicing and replacement. On the front panel there are the controls for output power and audio input level and meters for the main parameters.
Page 14
PTX30 UHT /S3 These circuits provide the automatic output power control, maintaining a flat power output response over the entire frequency range and the protection of the output stage against an excess of SWR and/or a short circuit on the feeder or the antenna. The RF final amplifier is broadband and guarantees an output level between 2 and 30 Watt over the entire frequency range.
PTX30 UHT /S3 5. Quick Start This chapter gives a concise view of the points that are necessary for the installation of the device. If any item is not completely clear, for example when you use the exciter for the first time, we strongly suggest to read throughly the manual. 5.1 Preparation Unpack the transmitter and before any other operation check the unit for any shipping damage and check that all the controls and connectors on the front and...
PTX30 UHT /S3 figure 5.1 Connect a dummy load with a continuous power dissipation of 30 W or more to the R.F. OUT connector on the rear panel. It’s preferable to connect also a through wattmeter, to check the reading of the internal wattmeter (see figure 5.1). Connect to the rear input "REMOTE"...

PTX30 UHT /S3 In the mixer mode (MONO-MPX) the section of stereo coding is by-passed and the "RIGHT" input can accept a mono signal, while the "LEFT" signal accepts a multiplex signal with a 100KHz bandpass; the SCA inputs remain the same. Three peak-to-peak detectors allow the analog meter to read the levels of the "RIGHT/MONO"...
PTX30 UHT /S3 9.6 Modmeter You can find this board on the left side of the front panel. This circuit displays the frequency deviation of your signal, measuring the rectified audio signal that is injected in the VCO’s varicaps. A switch selects the gain of the meter between two levels (100% and 10%), thus obtaining a more exact reading over low deviation levels (e.g..
PTX30 UHT /S3 9.8 CPU The CPU board is installed on the front panel in the central position, and includes the microcontroller (68HC11) and the related components, a led display and the buttons for the frequency setting. This circuit translates the number corresponding to the selected frequency into a binary code that is sent to the PLL programmable dividers to allow the VCO to lock on the right frequency.
