Seattle, WA — Novatech Instruments, Inc. is introducing the Model 425A, a precision 350MHz DDS signal generator packaged in a small shielded tabletop case. The instrument generates sine wave, LVDS, and LVCMOS output signals simultaneously.
|Programmable signal generator. |
The generated sine wave output frequency is directly programmable in 10microHz steps from 250kHz to 350MHz and includes a built-in prescaler and divider for generating low jitter LVCMOS clock signals down to less than 2Hz.
The signal generator uses the high performance AD9912 DDS IC which has 48-bit frequency tuning, 14-bit phase adjustment and a 14-bit reconstruction DAC. The high-resolution DAC enables the 425A to achieve low harmonic and spurious distortion. In addition, it has 10-bit amplitude control and an internal 1.5ppm temperature-compensated crystal oscillator (TCXO) that can be phase locked to an external 10MHz reference. Locking to a reference gives the instrument the same stability and accuracy as the reference.
When multiple 425A units are locked to the same reference, they remain phase-synchronous. A direct clock input up to 1000MHz can also be selected.
The generator is controlled by short text commands to its serial port. Model SOF8_425 PC software is included, and provides menu selections for command generation along with the ability to run a sequence of commands from a user created file.
