ANALOG BENCH ATE
APPLICOS AWG18 Module
An 18 bit Arbitrary Waveform Generator for high-speed / high resolution waveform generation
This module features two dedicated signal paths: A DC to 100 MHz path which is optimized for accurate time domain and frequency domain measurements up to 30 MHz. And a dedicated AC path optimized for signals between 10 MHz to 100 MHz. In combination with the built-in filters it features a typical harmonics level of better than -80 dBc for the whole range.
The module features differential outputs with a programmable common-mode voltage. For single ended applications the positive output as well as the negative output can be used. The clock can come from the backplane or from the front panel. The module has 8 output ranges in steps of -3 dB, which covers a wide range of Unit Under Test input voltages.
The unit is an excellent choice when exceptional signal integrity in combination with a high level accuracy is required. The 8M-word (16M-byte) waveform memory allows very complex signal shapes to be generated. For higher output frequencies the waveform can be improved by using the x2 or x4 interpolation modes, resulting in maximum sample frequencies of 600 MS/s or 1.2 GS/s respectively.
The LF path combines high DC accuracy and fast level settling with an excellent dynamic signal performance up to 30 MHz.
This allows precision time domain measurements as well as high quality dynamic measurements. The 10 MHz to 100 MHz signal path excels in dynamic signal generation. It features a filter-bank with 7 Low Pass filters, if desired the user can change any filter module with a custom version allowing an even better dynamic performance at user specific frequencies.
The jitter added to the applied front- or backplane clock is typically less than 0.2 ps.
