PXA7243 VX Instruments 1-Channel, Isolated, 1-Slot, 200 MS/s PXI Arbitrary Waveform Generator

The VX Instruments PXA(e)72xx Series Arbitrary Waveform Generators is based on the "Flexible Configurable PXI(e) Platform" (FlexCPeP).

The PXA(e)72xx ArbGen family features up to two simultaneously working channels with up to 200MS/s, 16 Bit resolution and an output voltage up to +30V or +/-15V. Every channel is equipped with up to 16MB memory. The whole amount of up to 8 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(e) device for 1 or 2 slots.

Predefined waveforms (DC, sine, square, triangle, sawtooth) can be configured via software driver. Furthermore it is possible to load an user created waveform.

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 completely independent. The great amount of trigger capabilities results in multiple sophisticated instrument and channel synchronization possibilities.

Arbitrary waveforms can be loaded via data files into the on-board memories for up to 8MS waveform data and 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.

The standard output voltage is +/-15V (30Vpp). With an optional extension the output stage can be switched to achieve output voltages up to +30V into high impedance load. This allows high voltage waveform stimulation without additional signal conditioning.
