Tektronix 1405
TV Sideband Adapter
Description
The Tektronix 1405 Sideband Adapter will works with the 271X Series Spectrum Analyzers that will analyze the sideband and in-band response of a television transmitter. It will generate a composite video signal, the "picture" portion of which is a constant amplitude sinusoidal signal that will sweep continuously and periodically between 0 and 15 MHz. This signal is applied as modulation to a modulator or a transmitter. The output is displayed on the spectrum analyzer and will appear as a response curve, to within ±0.2 dB, of the transmitter being tested.
The 1405/Spectrum Analyzer combination displays frequency characteristics of RF and IF circuits with frequencies to 1 GHz. Video circuits that can also be analyzed.
