The HVAWG-1280 is a high voltage, multichannel, arbitrary waveform
generator. The instrument supports 128 separate outputs channels,
simultaneous updating of all channels, a 0 to 200 voltage swing, 100mV
accuracy, and 2 million channels samples per second [note 1]. The
instrument may be rack mounted and is connected to the PC through the
parallel printer port.
[Note 1] : 100 KHz maximum sampling rate for any single channel.
Total channel samples per second is sampling rate time the number of
channels. 15 KHz maximum sampling rate when driving all 128
Host Computer Control
The HVAWG is controlled by a host computer parallel port, such as a PC
running Windows or Linux, or via a RS-232 serial port. Prepackaged
software or new application specific code can be written. The HVAWG
comes with example applications, libraries, and C source code.
- 128 output channels, in multiples of 16 channels
- 0.0 to 200.0 volt output range
- 25 mV resolution with +-50 mV absolute accuracy
- 50 mV readback resolution with 100mV accuracy
- 15,000 KHz maximum sampling rate on 128 channels
- Three trigger sources: External, software, internal periodic.
- Storage for 4 million samples
- Dimensions : 17 x 15 x 7 inches
The HVAWG was originally designed for experimentation with an optical
MEMS (microelectromechanical system) device. The HVAWG may also be
used with piezo stacks.
Output Amplifiers The standard HVAWG outputs are designed to
drive high impedance loads with upto 500pF of capacitance. The output
amplifier can supply 1.25mA @ 0.0V and derates at 6uA per volt. The
amplifier can sink in excess of 10mA, limited by a power rating of
1000mW per channel. Small signal bandwidth is 7 KHz. Unloaded
slewrate, (0 to 200V), is better than 1V per uS
An alternative output amplifier permits bipolar output, with a 25mA
peak current drive. The amplifier can be customized to drive higher
capacitance loads as required in the end application.
