Burst Mode
The burst mode is an extension of the triggered mode where the Model
3153 can be programmed to output a pre-determined number of
waveforms. The source to trigger the counted burst cycle can be
selected from a front panel connector, VXI backplane trigger lines, or
from the built-in trigger generator.
Gated Mode
In gated mode, the Model 3153 circuits are armed to generate output
waveforms as long as a gating signal is present. Unlike the triggered
mode, the gated mode is level sensitive. When the gating signal goes
low, the waveform at the output connector is first completed and the
output goes to an idle state. The idle amplitude level, after the gating
signal goes low, is the last point on the waveform.
Output Type
The Model 3153 can output three types of waveforms: standard (Fixed),
arbitrary (User) and sequenced waveforms. Different waveform types
may be assigned to each channel. Waveform type assignments for each
channel are retained in separate mode as well as in master-slave mode.
Descriptions of the various waveform types that the Model 3153 can
generate are provided below.
Standard (Fixed)
Waveforms
The Model 3153 generates waveforms from a memory that has to be
loaded before the instrument can generate waveforms. There are a
number of memory options that are available with the instrument.
Memory option must be specified at the time of purchase.
Field
upgrade of memory options is not available
. On power up, the
waveform memory has no specific data. The sine waveform, being the
default waveform on power on, is computed and loaded to the waveform
memory as part of the reset procedure. From this moment on, every time
that another standard waveform is selected, it is being computed and
loaded to the waveform memory.
Waveforms are written from the same start address. Therefore, every
time that a new waveform is selected, there is some minimal time for the
processor to compute and download the data to the memory.
The Model 3153 can be programmed to output nine different standard
waveforms shapes: sine, triangle, square, pulse, ramp, sinc (sine(x)/x)
pulse, pulse, gaussian pulse, exponential pulse, and DC. There are
number of parameters associated with each waveform which, modify the
shape of the waveform to better suite your needs. For example, different
start phase for the sine waveform can be programmed for each channel
to create phase offsets between two or three output channels.
