3151 And 3151A User Manual

Besides its normal continuous mode, the Model 3151/3151A offers a
variety of interrupted modes. The output waveform may be gated,
triggered, or may generate a counted burst of waveforms. A built-in
trigger generator with a programmable period can replace an
external trigger.
The Model 3151/3151A generates arbitrary waveforms with 12 bits of
resolution. There are nine standard waveforms which are memory-
resident. Other waveforms may be generated, either manually or
downloaded from the controller to the instrument using shared
memory or standard data bus transfer. Waveforms may also be
generated using the WaveCAD program.
The Model 3151A waveform generator is a digital instrument.
Besides its standard waveforms, any waveform it generates must first
be loaded into the arbitrary waveform memory. The arbitrary
waveform memory is a bank of 8-bit words. Each word represents a
point on the waveform. Each word has a horizontal address that can
range from 0 to 523288 (64536 for the Model 3151) and a vertical
address 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 D/A converter. The D/A
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.
The Model 3151/3151A is fully programmable using SCPI commands
and syntax. There are two ways to program the Model 3151/3151A,
the first being low level programming of each individual parameter.
The second alternative is to use the VXIplug&play driver for high
level programming. The VXIplug&play driver simulates a mechanical
front panel with the necessary push buttons, displays and dials to
operate the Model 3151/3151A as a bench-top instrument. The
Model 3151/3151A 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.
A number of options are offered with the Model 3151/3151A.
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 3151/3151A options are 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 Model 3151/3151A options is given below:
