  • Page 32: Afc (Automatic Frequency Control)

    Chapter 6 - SAT Measuring Range 6.2.5.1 AFC (Automatic Frequency Control) The device operates with the AFC switched on in the standard settings. This means that if the DVB-S/S2 receiver detects a frequency offset between the transmitter and the receiver, the tuner on the receiver is adjusted accordingly so that the frequency offset disappears.

  • Page 33: Mer Measurement (Modulation Error Rate)

    Chapter 6 - SAT Measuring Range 6.2.7 MER measurement (Modulation Error Rate) In addition to measurement of the bit error rate, it is established practice with digital transmission to also measure MER. It is defined in ETR290. MER is calculated from the constellation points. It is the counterpart to S/N measurement with analog transmission methods.

  • Page 34: Lnb Supply

    Chapter 6 - SAT Measuring Range LNB supply The measuring receiver controls a connected LNB or multi-switch with the conventional 14/18 V – 22 kHz control (max. 4 SAT-IF layers) or with DiSEqC control. The supply is short-circuit proof and provides a maximum current of 500 mA. The instrument automatically switches off the LNB supply if there is a short-circuit or if the current is too high.

  • Page 36: Diseqc

    Chapter 6 - SAT Measuring Range 6.4.3 DiSEqC DiSEqC (Digital Satellite Equipment Control) defines a standard which transfers the control commands from the master (e.g. receiver) to the slave (e.g. multi-switch, positioner) via FSK (frequency shift keying of 22 kHz) on the RF cable. DiSEqC is backwards compatible to the 14V/18V/22 kHz control.
  • Page 37 Chapter 6 - SAT Measuring Range requires multiple repetitions of the DiSEqC command. See the example that follows for further information. The settings for the SAT-IF layer and the satellite position are identical to those for V1.0. Added to this is the control of ‘Uncommitted switches’, which is operated under LNB -> Uncommitted Switch.

Figure 6-14 DiSEqC 1.2, menu drive After the menu is opened, the menu item STOP (motor is stopped) is activated. While you press the left arrow key, the rotor moves in the easterly direction and stops immediately after releasing the key.

  • Page 40: Diseqc V2.0 Control

    Chapter 6 - SAT Measuring Range Recall: With the menu item Go to, you can recall a previously stored rotor position. The motor then turns to the saved position. Position 0 corresponds to the reference position 0 degrees. The most recently recalled motor position is shown on the display.

  • Page 41: Activation And Configuration

    Chapter 6 - SAT Measuring Range 6.4.4.1 Activation and configuration The Key LNB -> DiSEqC -> UNIC activates the UNICABLE control. A menu is then displayed which can be used to edit the relationship between the satellite channel router (SCR) address and the center frequency of the user band (UB) band pass slot that the measuring receiver is to use: SCR-ADR.
  • Page 42 Chapter 6 - SAT Measuring Range Here you can set the UB center frequency that corresponds to the selected SCR address. This is the frequency that a connected receiver needs to tune to. Use the ← and → keys, or the numeric keypad to set the UB center frequencies within the range from 950 MHz to 2.150 MHz.

  • Page 54: Scan

    Chapter 7 - TV Measuring Range 7.2.1.3 Scan You can use this function to scan the entire TV range for analog TV signals. For this, the instrument must operate in channel input mode. In this operating mode, the arrow keys have a dual function. After entry of a new channel, the menu item 2.FUNCTION is not inverted.

  • Page 55: Noise Margin (Nm)

    Chapter 7 - TV Measuring Range 7.2.1.6 Noise Margin (NM) In contrast to digital signals there is no fixed point here at which the image display is disturbed, but a continuous deterioration of the image. Therefore here the value S/N = 45 dB for the minimum quality at the BK socket according to EN 500083-7 is taken as reference value.

  • Page 56: Symbol Rate Input

Figure 7-10 DVB-T selection bandwidth The bandwidth of the COFDM signal is set via BANDWIDTH -> AUTO, 8MHz, 7MHz or 6MHz. In the AUTO setting, which is also the default setting, the measuring instrument uses the channel bandwidth that is stored in the respective channel table.

  • Page 64: Dvb-T Parameters

    Chapter 7 - TV Measuring Range 7.2.2.3.3 DVB-T parameters As soon as the receiver has completed the synchronization process, several parameters are shown on the display. When LOCK appears, it means that the digital receiver is receiving a valid data stream.

Figure 7-12 DVB-T parameter information One of the parameters, the Cell ID, uniquely identifies the cell of the transmitter. 7.2.2.3.5 BER measurement (Bit Error Rate) The measurement of the bit error rate aids in the determination of the quality of a DVB signal.

  • Page 66: Noise Margin (Nm)

    Chapter 7 - TV Measuring Range 7.2.2.3.7 Noise Margin (NM) In case of white noise a limit value of MER for the minimum signal quality (QEF) can be determined dependent on the modulation type and the FEC.The difference of MER to this limit value corresponds to the system reserve NM (noise margin).
  • Page 67 Chapter 7 - TV Measuring Range Figure 7-14 DVB-T Impulse response Figure 7-14 shows an impulse response with a primary impulse (left picture edge) and several secondary impulses at a distance of approximately 23 km from the primary impulse. You can move the cursor (small triangle) left and right using the ←/→keys. At the top area of the screen, the distance of the secondary impulses and their attenuation (-21 dB) in relation to the primary impulse is displayed.

  • Page 68: Pe Measurement (Packet Error)

    Chapter 7 - TV Measuring Range 7.2.2.3.9 PE measurement (Packet Error) Short interruptions in the DVB-T signal usually cannot be detected using MER and BER measurement. They can make entire packets in the transport stream unusable for the MPEG decoder, however. This can lead to short picture freezes or sound that crackles. The extent of this depends largely on the receiver hardware.

As a result, the measuring instrument’s optical receiver can be operated with up to 8 dBm of continuous power. However, the optimal range for the receiver is from -7 dBm to +3 dBm. At lower power levels, the reception quality is reduced because of the receiver noise.
