    Part III: Background and Concepts Principles of Gated Measurements Field A television image, or frame, is composed of 525 (or 625 lines). When displayed, these are delivered in two successive fields of 262.5 (or 312.5 lines) interlaced together on a CRT. When Field is set to Entire Frame, the line count starts at line one in field one (often referred to as the “odd field”) and ends at 525 (or 625) in field two (often referred to as the “even field”).
  • Page 104 (at the specified field). The S7200 first measures the video carrier peak level during the sync pulse. Then, while the quiet line inserter removes a specified line at the same time in every frame, the instrument uses the gated function to measure third order beat.
  • Page 105 Part III: Background and Concepts 8-3.2 Video Parameters Gated Measurement VITS (Vertical Interval Test Signal) In the past, engineers often used full-field test signal to test TV systems. This particular test process requires the field or HE engineer to interrupt the specific channels from broadcasting.

    This chapter will provide a basic overview of satellite transmission concepts, related to designing a satellite channel plan. For instructions on creating a satellite channel plan on the S7200, see Section 3-2. A satellite channel plan is composed of satellites and satellite transponders. A transponder is a device that receives signals transmitted from ground stations on Earth, amplifies them, and transmits them back down to the desired receiver .

  • Page 110: Polarization And Lnb

    Part III: Background and Concepts Polarization and LNB Satellite signals have two types of polarization: circular and linear. Circular polarization can be divided into right-handed (or clockwise) and left-handed (or counterclockwise); while linear polarization can be divided into horizontal and vertical. Most satellites use the horizontal and vertical polarization transmission signals. Today, many new products combine the LNB and Feedhorn into one: LNBF (LNB with Feedhorn).
  • Page 111 Part III: Background and Concepts Some manufacturers provide double local oscillators for Ku band LNB. With two sets of circuits and local oscillators for different polarizations (9.75GHz and 10.6GHz are commonly-used), users can use a 0/22kHz impulse signal to control low-frequency and high-frequency band LO.

  • Page 112: Satcr Overview

    Part III: Background and Concepts SaTCR Overview Unicable LNBs (see below) receive Ku-band satellite signals the same way that traditional LNBs do. The difference is the addition of SCR and MCU chips. When the receiver’s low-noise amplifier receives satellite signals, they may be of four different frequency bands: low- and high-LO vertical polarization (V/L and V/H), and low- and high-LO horizontal polarization (H/L and H/H).

    The S7200 offers automatic or manual RBW selection depending on frequency/span/sweep time selection and/or what the user is looking for. The S7200 uses digital IF and leverages DSP (Digital Signal Processing) techniques of implementation, so the digital filters won’t drift as analog filters would in older spectrum analyzers.
