DDS/PLL-based Programmable Frequency Synthesizer Model DPL3.2GXF
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 ~ 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~ +14dBm with ALC function.
- 0.1 degree step phase control
- 0.1dB step output level control
- Low phase noise
- the stable output level with ALC
- 0.001Hz frequency resolution
- low harmonic
- single power supply +5V
- wide band (5MHz~3.2GHz)
- Optional Board available to control settings without PC

Frequency setting board FIX-2.5GX
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.
