Frequency Synthesizer Model : DPL-3.2GXF
Frequency Synthesizer
Programmable Frequency Synthesizer
Product Summary
DPL-3.2GXF is a wide band synthesizer utilizing 48 bit DDS (Direct Digital Synthesizer) and PLL(Phase Locked Loop) technique. It provides pure sine wave signal output from 5MHz to 3.2GHz in 0.001Hz steps.
It is completely phase synchronious to an external clock and a phase offset can be set too.
The stable output level has been achieved in the range of -40dBm to +14dBm with ALC function.

Frequency setting board FIX-3.2GX
FIX-3.2GX is an optional control board for DPL-3.2GXF to set frequencies, output level, ON/OFF set of RF and so on with a LCD display and an encoder on the board.
Also, the level converter is available for CMOS, the differential PECL, and the differential LVDS which are very useful as a logic circuit clock source.
