HP E1564A 800 kSa/s, 4-Channel Digitizer

The HP E1564A digitizer is a C-size, 1-slot, register-based VXI module. It is ideal for measurements in electromechanical design characterization, particularly in environments with high levels of electrical noise. Engineers and technicians in product development and engineering research test groups can fully characterize electronic and mechanical transient waveforms with this highly accurate digitizer.

Each channel of the HP E1564A digitizer has its own analog electronics, including four (4) selectable input filters, 800 kSa/s 14 bit A/D converters, and independent channel isolation.

The HP E1564A is configured for PC SIMM memory, scalable from 4 Mbyte to 64 Mbytes. The large memory can easily capture transients and act as a FIFO to allow continuous digitizing while unloading data with block mode transfers.

Specifications

Sample rates: 1 Sa/s to 800 kSa/s Resolution: 14 bits Input voltage ranges: 62 mV to 256 V Independent channel isolation: 60 V Common mode rejection: 113 dB, DC - 60 Hz

Time Base and Triggering

All channels sample simultaneously with a single internal or external time base. Triggering can be set up for either time or event modes with programmable pre-trigger and post-trigger reading counts.

Programming

The HP E1564A has a simple programming model which includes a data FIFO or flat file memory model for the A/D converter, 16 bit integer data corrected for offset and gain errors, and a current value table to retrieve the current sample of data.

Calibration

The HP E1564A provides a calibration source with flash ROM for holding calibration constants.
