HP E1563A 800 kSa/s, 2-Channel Digitizer

The HP E1563A digitizer is a C-size, 1-slot, register-based VXI module. It is ideal for measurements in electronic production test, particularly in environments with high levels of electrical noise. Engineers and technicians in manufacturing test groups can fully characterize electronic transient waveforms with this highly accurate digitizer.

Each channel of the HP E1563A digitizer has its own analog electronics, including switchable 25 kHz input filters, 800 kSa/s 14 bit A/D converters, and independent channel isolation.

The HP E1563A is configured for PC SIMM memory, scaleable 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.

[ Features ]

1-Slot, C-size, register based
800 kSa/s sample rate with 14 bit resolution
Input ranges up to 256 V, channel isolation 256V
Common mode rejection 113 dB

[ Specifications ]

Time Based Triggering
Both 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- and post-trigger reading counts.



Programming
The E1563A 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.

¹ Valid within the range of 0 °C to 55 °C. A zero offset 
calibration for all channels must be performed if the instrument 
experiences a temperature <0 °C or >55 °C for these 
specifications to remain valid.

² Specification is valid when tested at a temperature 
within ± 5 °C of the calibration temperature.

³ Amount of error that must be added for each °C outside 
of ± 5 °C of the calibration temperature.
