    The GFT7048 is a 48 Channel Digital Pattern Generator that operates either as a standalone device, or as a component in a timing system. In a timing system, the GFT7048 is operated in conjunction with a GFT3001 Master Transmitter that controls and synchronizes several GFT7048 DPGs via optical fibers.( for more information about timing system ask to factory)

    The generator provides two trigger modes: External mode from trigger input or internal mode from one frequency programmable generator.

    One “T0” channel is used as a time reference for all the LVDS channel Outputs.

    A global delay up to 10 µs may be used to control skew between GFT7048 in a timing system configuration (optical network compensation).

    A fine delay function (<50 ps resolution) on each channel pattern may be used to adjust skew between pattern channels.

    Eight (8) different patterns of 48 channels can be set and saved in the generator. Each pattern channel is 20,000 samples of 1.041 ns resolution (about 20.833 µs total length).

    Seventeen (17) Analog and Digital I/O may be used to control and monitoring some devices of your application (high voltage power supply, sensor, switch …).

    GFT7048 parameters can be locally controlled over the front panel keys and LCD display, and remotely controlled via Ethernet (10/100/1000 Mb/s) or Internet (web page from internal web server).

    The GFT7048 is low profile 19", 2U rack mountable instrument.

    Application: This Digital Pattern Generator is well suited for FPGA or ASIC simulation or emulation, production test, digital stimulus and application where speed, resolution, channel number are critical.The GFT7021 is an external clock triggered short pulse generator. This compact module delivers up to 2V under 50Ω, 40ps to 250ps width pulses.
