3153 User Manual
Getting Started 1-4
The arbitrary waveform memory is a bank of 12-bit words. Each word
represents a point on the horizontal (or time) waveform scale. Each word
has a horizontal address that can range from 0 to 8388560 (with the 8
Meg option only) and a vertical address (or voltage level) that can range
from -2047 to +2048 (12 bits). Using a high speed clocking circuit, the
digital contents of the arbitrary waveform memory are extracted and
routed to the Digital to Analog Converter (DAC). The DAC converts the
digital data to an analog signal, and the output amplifier completes the
task by amplifying or attenuating the signal at the output connector.
There is no need to use the complete memory bank every time an
arbitrary waveform is generated. Waveform memory can be divided into
up to 4096 smaller segments and different waveforms can be loaded
into each segment. The various segments may then be loaded into a
sequence table to generate long and complex waveforms. The
sequence table can link up to 4096 segments, while each segment can
loop up to 1 million times. Note that sequence generators are separate
for each channel. The separation exists also in master-slave mode.
The Model 3153 is fully programmable using SCPI commands and
syntax. There are four ways to program the Model 3153, the first being
low-level programming of each individual parameter using SCPI
commands. The second alternative is to use the
VXIplug&play
driver’s
Soft Front Panel (SFP) for high-level programming. The
SFP
driver
simulates a mechanical front panel with the necessary push buttons,
displays and dials to operate the Model 3153 in a similar way to using a
bench-top instrument. The third way to program the 3153 is by using
either the LabVIEW or LabWindows/CVI drivers. The fourth way to
program the 3153 is via the WaveCAD program. The Model 3153 will not
operate without being programmed. Therefore, it is recommended that
the user become familiar with its basic features, functions and
programming concepts as described in this and the following chapters.
Options
A number of options are offered for the model 3153. Compare the option
number with the number that is printed on the instrument to verify which
of the options is installed in your instrument. Note that all Model 3153
options are only installed in the factory. Contact your nearest Racal
representative if the number printed on the case does not reflect the
correct version ordered. The list of available options is given below:
1. 407677-001 – Model 3153, Waveform Generator, channel 1 - 512k
RAM, channels 2/3 – 2Meg
2. 407677-002 – Model 3153, Waveform Generator, channel 1 –
2Meg, channels 2/3 – 4Meg
3. 407677-003 – Model 3153, Waveform Generator, channel 1-
2Meg, channels 2/3 – 8Meg
