I also like the ideas of a 1Gs 8-channel 14-bit ARB, it would be very interesting to have it on my desk but to be fair I do not have $1000 and anything that sticks beyond 1MHz analog bandwidth is beyond my field of interest. I need a true arbitrary waveform generator (and not sin+square), for embedded, testing and debugging. Current micros are clocked in the range of 50-100MHz, they cannot cope with signals from >1MHz bandwidth (even a stupid PID @ 100kHz is a challenge on a 100MHz micro) so I really have no interest in a 5MHz triangle waveform.
What I was hoping to build looks similar to the FG085 but with a PC/Windows based front end for versatility. Thanks
FG085 looks too limited in functionality for me but the bandwidth is ok-ish.
I need:
-a sine sweep, from A to B, in logarithmic scale. Two decades at least. 1Hz:100Hz, 2Hz:200Hz, 5Hz:500Hz,..., 5kHz:~500kHz
-random noise generator, with replay (so not that random)
-trapezoidal shape (for servo control)
-ramp with reset output (for integrating opamp with zeroing)
-external output trigger, input trigger and clock (to synchronize that with external gear for debugging, or to cascade/parallel with second arb generator),
-incremental encoder/pushbutton emulator with switching noise (for testing noisy encoder/button interfaces)
-hardware keyboard and standalone operation not required
-USB interface
