    The TV1350

    The TV1350 family is capable of solving all problems in the field of TV reception and demodulation.

    The Tektronix TV1350 Television Demodulator provides an accurate link between RF signals and baseband measuring equipment. It captures and demodulates TV signals with true fidelity and full transparency and is ideal for monitoring testing and adjustment applications in both TV transmitter and CATV systems.

    Synthesizer frequency processing provides continuous coverage of all TV bands and cable channels. Channel selection is simply a matter of entering the channel number manually from the front panel or via the remote interface. A search mode facilitates automatic tuning. Accuracy is <2.5 kHz and carrier offsets to ±100 kHz are compensated automatically.

    Up to 20 dB of built-in RF attenuation is selectable, either manually or automatically. The RF input level is indicated on an analog meter, with the optimal input level marked directly on the meter. Highly effective adjacent channel suppression is provided by a SAW filter.

    The TV1350 offers user-selectable envelope or synchronous detection. Two isolated video outputs and two quadrature signal outputs facilitate convenient measurement of incidental phase modulation of the video carrier to determine the intercarrier S/N ratio of the sound channel. The quadrature signal output is especially suited for adjustment of linearity and phase equalizing circuits in TV transmitters. A stable zero carrier reference enables accurate measurement of the video modulation depth.

    Frequency deviation of the sound carrier can be measured on the front panel analog meter. Narrow, wideband, mono and stereo BTSC audio outputs are available. Complex audio processing circuits maintain equal deviation of the two audio demodulators to ensure low stereo crosstalk. A built-in loudspeaker with a volume control and a headphone jack provide convenient monitoring of the audio signal. Parallel remote control capability is standard. An IEEE-488 (GPIB) bus interface is optional.

    Key Features Common to the TV1350 Products Are:

  • Two isolated video outputs
  • Two quadrature outputs for ICPM measurements
  • Zero carrier reference pulse
  • Switchover from synchronous to envelope detection

    Special Features

    TV Test Receiver and Demodulator TV1350

  • Channel selection with digital entry of channel number either in manual or in remote mode
  • Automatic control of frequency offset up to ±100 kHz
  • Continuously tunable in all TV bands, also in special channels from 54 MHz to 880 MHz
  • SAW filter switch-selected on front panel for adjacent channel suppression Optional GPIB control (IEC 625-1/IEEE 488), thus channel selection also possible by entering the vision carrier frequency
  • Reduction of IF gain allowing operation at high input levels (demodulator mode) and thus providing increased video S/N ratio
