VX4101A MultiPaq Instrument User Manual
1–5
The Digital to Analog Converter (DAC) includes an eight-channel arbitrary
waveform generator. Waveform length can be generated with one to 1024 sample
points at sample rates from 3.662 to 15 kHz. Signals are generated on all eight
channels when the DAC is initiated. A default 0 VDC output will be set on
unused channels.
The VX4101A DAC includes the following features and functionality:
H Eight synchronized, 12-bit digital to analog channels synchronized to a
single programmable sample clock (3.662 Hz to 15 kHz)
H Amplitudes of –14 V to +14 V are supported with 8 mV resolution on each
channel
H Each channel is separately programmable to generate a different waveform
H Each channel has 1024 points of trace buffer memory available for waveform
synthesis
H Waveforms can be repeated either continuously or with a programmable
count and repetition frequency.
NOTE. Setting the sample rate, segment length, and repetition frequency the same
for one channel sets them for all channels.
The high-current relay drivers include the following:
H Eight lines of high-current outputs
H Open collector, 100 mA sink per output
The scanner master control enables you to use the VX4101A to control the
Tektronix SurePatht family of VXI relay modules, including the VX4320,
VX4330, VX4350, VX4351, and VX4380. Some of the features of the Sur-
ePatht family are as follows:
VX4320 1.3 GHz RF Multiplexor. This module is a single-wide VXIbus module
intended to switch RF and high-frequency digital signals. It is arranged as eight
1 × 4 coaxial switches with a 50 W characteristic impedance. Each 1 × 4 section
has five type SMB male snap-on subminiature coaxial connectors.
VX4330 120-Channel Scanner/Multiplexor. This module provides six 1 × 10 4-wire
multiplexor sections. Each of these six sections can be independently configured
under software control as two 1 × 10 2-wire multiplexor, a 1 × 20 2-wire
multiplexor, or as a 1 × 40 1-wire multiplexor. In addition, each section can be
