Product Description:
Analogic - Data Precision DBS 8751A 16-Bit, 200kHz, 4 ch. D/A Waveform Generator
Feature:No. of Channels: 4ch
Frequency, Sine: 21kHz
Introduction
The DBS 8751A/8752A is a high speed, 16-bit, 4-channel waveform generator
of superior performance, fully compliant with the VXI subsystem specification
Rev. 1.3 for a Register Based ôCö size module. The DBS 8751A/8752A is de-signed
to meet the stringent requirements of waveform generation for testing of
audio range components such as Codec chips used in communications equip-ment
and driving exciters for vibration testing.
Each output channel of the DBS 8751A/8752A consists of a 64K word block of
data memory that is transformer coupled to a high speed, 16-bit, digital-to-analog
converter (DAC); followed by a deglitching amplifier; a 6-pole, 21 kHz Butterworth
filter of superior performance; and 2 differential/single-ended output drivers per
channel. All channels are updated by a precision, programmable sampling clock
whose rates are 204.8 kS/s to 3.6 kS/s in 1006 steps. The user can supply sam-pling
clock and external trig Tests Audio Range Components
