My Dream Handy AWG

My Dream Everyday Arbitrary Waveform Generator

· 14-bit, dual channel, 200MHz+ sampling, 40-60 MHz sinewave output. Additional 8-bit digital parallel output for user stimulus generation. The parallel output to be represented as a separate trace in waveform files.

· 32K-256K samples in DRAM. Import data from oscilloscope trace files, Matlab binary and Windows WAV file.

· Standard preset waveforms (ramps, squarewave, triangle, trapezoids, Sinc(x), AWGN noise).

· +/-10V swing on 50 Ohm load, ideally low/no dependency of amplitude on load impedance (above 50 Ohm). Use xDSL driver ICs as output stage. Channel output inversion.

· Optional Power amplifier module (25V, 1A)?

· Must have galvanic isolation of signal ground from power ground (or ability to work off external or internal optional battery). The main trouble with all AWGs I tried some residual ground loop noise.

· Is it possible to have differential out as an option? Off-the-shelf xDSL drivers are differential.

· CMOS/TTL synchronization output (start + DDS increment clock). CMOS/TTL phase reset input.

· When the sweep mode is selected, output the sweep as voltage for plotting of frequency response charts. Such output is missing on my AWG. Linear and log sweep with settings for start and stop frequencies of DDS.

· Remote control on Ethernet and USB, VISA support

· Single button recall of 10-16 user configurations (all parameters at a time). There are too many parameters to change when retuning manually. Having instant access to setting sets will be essential.

· Selectable state of output disable: Zero V, +V max, -V max. For instance, when AWG drives the gate of P-channel MOSFET, the return to zero will open it and it is not always desired.

· Large screen (6-8”). Does not need to be as big as in the scope.

· LED highlighting the output connectors when they are active

· Reliable rotary encoders in the knobs – these are first points of failure.
