The PM5690 TV Multichannel Converter is a highly stable RF converter with calibrated output level.
It converts a complete IFTV signal, between 36 MHz - 46 MHz, to any channel between 8 MHz - 950 MHz.
The PM 5690 works with the PM 5670 and PM 5680 IF modulators in an integrated measuring system.
The PM 5690 has applications in manufactur­ing video recorders and TV receivers, including multi-standard receivers.
It is easily adapted to computer-controlled test and measuring sys­tems;
in particular, the GPIB bus can be used to control levels and frequencies.
In broadcast organisations and tele-admini­strations, PM5 690 is ideal for laboratory applications, such as testing
and repairing transposers and demodulators. In the field, PM5690 is well suited for transmission and propagation tests.
