MO-160 DVB-T Modulator

Product catalog summary

General Overview:
The MO-160 / 161 is a DVB-T modulator housed in a 19" 1U chassis, featuring an ASI MPEG-2 Transport Stream input. It supports any incoming bit rate below the DVB-T specification limits and adapts the input TS bit rate by stuffing with NULL packets, requiring PCR re-stamping to maintain jitter within DVB limits. The modulator supports various transmission modes and user-selectable channel bandwidths of 6, 7, or 8 MHz. Configuration is facilitated via a front panel LCD and intuitive menu navigation.

Specifications:

Inputs: Two DVB-ASI inputs and one DVB-SPI input, supporting TS packets of 188 or 204 bytes, with automatic detection and support for burst and continuous packet modes.
IF Output: 50 Ω BNC connector, frequency range of 32 to 36 MHz, with selectable spectrum polarity and fixed power level of 0 dBm.
RF Output: 50 Ω N-type connector, adjustable frequency range of 475 to 875 MHz (45-875 MHz for MO-161), with selectable spectrum polarity and power level adjustable from -27 to -87 dBm.
DVB-T Parameters: Supports IFFT sizes of 2k and 8k, various guard intervals, code rates, and constellations (QPSK, 16QAM, 64QAM), with hierarchical modes and MFN operation available.
Remote Control: RS-232C interface for remote configuration.
Power Supply: Operates on 90 - 250 V AC with a consumption of 20 W.

Key Features:

High MER (> 35 dB) and frequency agility in 1 Hz steps.
Service selection without table rebuilding (PID Filtering).
Optional +6 dBm output available.

The unit has one ASI MPEG-2 Transport Stream input. The MO-160 / 161 is able to work with any incoming bit rate as long as this is strictly lower than the value given in the DVB-T specification for the modulation parameters in use. The input TS bit rate is adapted to the useful bit rate required by the DVB-T signal by stuffing the TS with NULL packets (packet stuffing). This stuffing process alters the sequence of PCR values embedded in the TS. These values have to be re-stamped for the resultant PCR jitter to remain within the limits specified by the DVB. The modulator can be configured to generate any of the transmission modes listed in the DVB-T specification. The channel bandwidth can be set by the user to 6, 7 or 8 MHz as required by the application. The operation of the MO-160 / 161 is done via the front panel LCD display and controls. The modulator can be easily configured by navigating through the intuitive set of menus. ASI ► ► ►_i |-| SPI ► » * MD-IBD/IBI ► ► ► COFDM
