A multi-function generator designed specifically to offer better value compared to the established big players(Tek, Agilent/Keysight). This device competes favorably in terms of performance at a fraction of the cost.

Featuring an advanced DDS(discrete digital synthesis) capability, as well as a function generator mode for creating sine, triangle/square/pulse/noise, and other waveforms. There's also a built in frequency counter with an additional time interval mode.

Some of the unique features include a real time mode over the high speed USB interface and an open software API(Linux and Windows) for direct access the the hardware. This allows users to get creative and implement custom applications where high speed digital to analog conversion can take place in real time, and sustained indefinitely(limited only by the USB bandwidth).Download Datasheet.

Is the unit field upgradable ?

Yes, firmware can be upgraded over the USB interface.

Can multiple units be connected together ?

Yes, there are currently two modes of operation. Trigger mode and synchronization mode.

Synchronization mode allows multiple units to run off the same clock. An example would be 3 units daisy chained together, outputting 1khz, 2khz, 4khz sine waves that are all in phase and without drift or wander.

In trigger mode a unit sits idle until it sees a start signal on the sync in connector. Additionally it can output a start pulse once it reaches the Nth(user selectable) sample. This allows pricise triggering and sequencing between multiple units. More advanced trigger options may be added in the future via firmware upgrade.

What is 8 bit mode ?

8 bit mode allows the memory depth to be effectively doubled, at the expense of a reduced vertical resolution(reduced to 8 bits).

This can be useful where the memory depth is a limiting factor, and 8bits of vertical resolution is adequate.

What is real time mode ?

In real time mode data is continuously sent from host PC over the USB interface to the device. This is useful when the size of the file to be outputted is larger than the capacity of the internal RAM.

This mode allows very large files to be outputted, where the size of the file is only limited by the host PC's hardware and bandwidth limits of the USB interface.

Buffer levels are displayed in real time, and any under-runs are reported and saved to notify the user that there was a hiccup and the system is having trouble keeping up.

Note:

The theoretical bandwidth of USB 2.0 is 480Mbit/s, however a more realistic sustained throughput is around 200Mbit – 300Mbit. This would allow a sustained output sampling rate of over 15Mega samples per second.

What is the frequency sweep ?

The device outputs a sine wave and keeps changing the frequency either up or down. Start frequency, end frequency, step size, duration and direction are all user specified.

What is the user oscillator socket for ?

Because the sampling frequency of the device is based on division/multiplication of the input oscillator, it sometimes helps to be able to change the oscillator to hit that exact desired frequency.

My waveform doesn't look right when I turn the offset knob all the way ?

The device is most likely just fine, the issue is that amplifiers in general don't work well at the extreme range of their power rails. Please google "amplifier clipping" for a more thorough explanation.
