This family of Arbitrary Function Generators is based on the “Flexible Configurable PXI Platform” (FlexCPP). This platform allows many variations of customer configured Arbitrary Function Generator (ArbGen) types.
High speed, high resolution arbitrary waveform generator
The PXA723x / PXAe723x ArbGen family features up to two simultaneously working channels with 150 MS/s, 16 Bit resolution and an output voltage up to +30 V or ±15 V.
Every ArbGen channel has its own 2 MB memory. The whole amount of 1 million samples can be partitioned into one or more waveform segments.
Depending on the number of channels and the floating option, the Arbitrary Function Generators are built into a compact 3U PXI device for 1 or 2 slots.
Built-in waveform functions
Predefined waveforms (DC, sine, square, triangle, sawtooth) can be configured via software driver. Furthermore it is possible to load an user created waveform.
Fully independent channels
Each channel has its own Clock-PLL, memory and state machine for START, STOP, TRIGGER, SAMPLING and SEQUENCING. This guarantees the two channels to work completly independent. The great amount of trigger capabilities results in multiple sophisticated instrument and channel synchronisation possibilities.
Complex waveforms without memory reloading
Arbitrary waveforms can be loaded via data files into the onboard memories for waveform data (1 MS) and sequence data (512 sequences). The memory can be segmented and sequenced in any desired order. Furthermore, amplitude and offset can be changed on the fly without writing new data into the memory.
High output voltages allows easy stimulation
The standard output voltage is ±15 V (30 V pp ). With an optional extension the output stage can be switched to achieve output voltages up to +30 V into high impedance load. This allows high voltage waveform stimulation without additional signal conditioning.
