HPS752 DVB-T SFN Modulator with 4*asi input and RF output
Outline
The HPS752 DVB-T Modulator is a high performance modulator developed according to DVB-T (EN300744) standard. It adopts advanced framing structure, channel encoding and modulation technology. It supports both MFN (Multi-frequency network) and SFN (single frequency network). It equipped with four ASI hot backup input, one GPS 10MHz input port and one 1PPS input port. In order to improve the output performance of the transmitter, this DVB-T modulator also simultaneously supports adaptive linear and nonlinear digital pre-distortion. Moreover, this device facilitates the local and remote control with SNMP software.
Features

· Support 1external GPS 10MHz clock and 1PPS input for SFN
· Support SFN and MFN
· Transmission mode(FFT): 2k, 4k, 8k
· MFN Hierarchical modulation: None, Alpha1, Alpha 2 and Alpha 4
· Transfer bandwidth2M, 5M, 6M, 7M and 8M
· Excellent RF performance, MER≥42db
· RF output frequency range 30~960MHz, 1hz stepping
· Supports adaptive linear digital pre-distortion (DPD)
· Supports adaptive non-linear digital pre-distortion (DPD)
· Constant temperature crystal oscillator, frequency stability is high up to 0.1ppm
· LCD/keyboard, SNMP software management
