The Tektronix 1705 Spectrum Monitor is a special purpose radio
frequency monitor designed for rapid response television satellite news
gathering applications.Using the 1705, an operator can identify the
spectral pattern of a particular satellite and transponder to determine
which video, audio, SCPC carries are present.It assists in the accurate
adjustment of azimuth , elevation and polarization of the
downlink/uplink antenna.It also provides a display of satellite and
locally generated signals.
Dual Band Operation
The
1705 features front panel selectable inputs for L-band (900-1450 MHz)
monitoring of television downlink signals from a low noise block
converter (LNB) located at receive antenna, and 70 MHz band (45-100
MHz) monitoring of the television uplink exciter or other IF signals.
Input frequency is displayed onscreen in both L-band and 70 MHz modes,
and the L-band readout may be reconfigured to display a satellite
frequency in the range of 0.9-20.0 GHz.A dc output is provided to power
the low noise block converter.
