FOR YOUR SAFETY
Before undertaking any troubleshooting, maintenance or exploratory procedure, read carefully the
WARNINGS and CAUTION notices.
This equipment contains voltage hazardous to
human life and safety, and is capable of inflicting
personal injury.
If this instrument is to be powered from the AC line (mains) through an autotransformer,
ensure the common connector is connected to the neutral (earth pole) of the power
supply.
Before operating the unit, ensure the conductor (green wire) is connected to the ground
(earth) conductor of the power outlet. Do not use a two-conductor extension cord or a
three-prong/two-prong adapter. This will defeat the protective feature of the third
conductor in the power cord.
Maintenance and calibration procedures sometimes call for operation of the unit with power applied and
protective covers removed. Read the procedures and heed warnings to avoid “live” circuit points.
Before operating this instrument:
1. Ensure the proper fuse is in place for the power source to operate.
2. Ensure all other devices connected to or in proximity to this instrument are properly grounded or
connected to the protective third-wire earth ground.
If the instrument:
-fails to operate satisfactorily
-shows visible damage
-has been stored under unfavorable conditions
-has sustained stress
Do not operate until, performance is checked by qualified personnel.

Introduction A detailed functional description is given following the general
description of the features, functions, and options available with the
Model 3153.
The Model 3153 is a VXIbus, single slot C-size 3-channel synthesized
Waveform Generator. It is a high performance waveform generator that
combines three separate and powerful waveform generators in one
small package. Each of the three channels can operate as a separate
waveform generator; having its own independent sample clock, trigger
input, waveform memory and sequence generator. In applications where
two or more channels must output synchronized waveforms, channel 1
takes control over slave channels 2, 3 or both.
In master-slave configuration, all three channels generate waveforms
from one sample clock source and start from one trigger source. The
master-slave mode ensures that all waveforms that are generated by the
three channels are fully synchronized in terms of frequency and start
phase of the output waveforms. In master-slave mode, the start phase
of each channel may be adjusted relative to the master channel.
The Model 3153 has three output channels. Each channel is completely
independent with its own set of input and output connectors. The
instrument connects through a common VXI ASIC device to the VXIbus
backplane from which it receives commands and waveform data. The
information that is downloaded from the backplane is distributed to the
various channels using 16-bit data and A32 address space. After
loading waveform data and controlling commands to the generator, each
channel can start generating waveforms.
The architecture of the 3153 is such that only channel 1 is allowed to be
programmed as master. Channels 2 and 3 can only be slaves. There
are 4 combinations of which the three channels can operate:
1) Each channel operates as an independent generator;
2) Channel 1 master, channel 2 slave;
3) Channel 1 master, channel 3 slave;
4) Channel 1 master, channels 2 and 3 slaves.
Being a master, channel 1 has a few features that are not available in
the slave units. Channel 1 can output waveforms with up to a 100 MSa/s
clock rate maximum, while the slave channels output waveforms at up to
50 MSa/s. The trigger level input for channel 1 may be programmed,
while the other two channels are sensitive to TTL levels only. Also,
memory options are not the same for all channels. The various memory
options are discussed later in this chapter. The generator, if not ordered
with special memory option, is shipped with the following memory
configuration: channel 1 with 512k, channels 2 and 3 with 2 Meg. Other
memory options are listed below.

Note:
Field upgrades for larger memory banks are not available.
Aside from the differences above, all channels have the same frequency
bandwidth, the same output power and the same operational flexibility
and performance.
The Model 3153 is completely digital. There are no analog functions
resident in its hardware circuits. Data has to be downloaded to the
instrument for it to start generating waveforms. The instrument can
generate nine different standard functions such as sine wave, square
wave plus seven other functions. Each time that a standard function is
required, the instrument has to calculate its coordinates and place them
in the waveform memory. Therefore, every time a standard function is
recalled, minimal time is required for the controller to compute the
function and load its data to the waveform memory.
The frequency accuracy of the output waveform is determined by the
clock reference. Using CLK10 as the reference oscillator provides 100
ppm accuracy and stability over time and temperature. If higher
accuracy and/or stability are required, one may connect one’s own
reference oscillator to a front panel input and use this input as the
reference for the three sample clock generators of the 3153. Frequency
may be is programmed with up to 9 digits, so using an external reference
is recommended, if you intend to utilize the full resolution provided by
the instrument.
Output amplitude for each of the channels may be programmed
separately within the range of 20 mV to 20 Vp-p into an open circuit, and
10 mV to 10 V into 50Ω. Amplitude and offsets are programmed with 4
digits of resolution.
Besides its normal continuous mode, the Model 3153 responds to a
variety of trigger sources. 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 be used as a replacement of
an external trigger source. As was discussed above, the channels can
operate separately from each other. Each channel has its own set of
output and input connectors. The trigger inputs are separate for each
channel as well. In master-slave configuration, the trigger input of the
slave channels are disabled and channel 1 trigger input is the only
active trigger input. The VXIbus TTLTrg0 through TTLTrg4 and
ECLTrg0 may be routed to any channel. However, in master-slave
configuration, active trigger signal is that which is applied to channel 1.
The Model 3153 generates arbitrary waveforms with 12 bits of vertical
resolution. Any waveform it generates must first be downloaded to
waveform memory.

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.

Safety
Considerations
The Model 3153 has been manufactured according to international
safety standards. The instrument meets VDE 0411/03.81 and UL 1244
standards for safety of commercial electronic measuring and test
equipment for instruments with an exposed metal chassis that is directly
connected to earth via the chassis power supply cable.
WARNING
Do not remove instrument covers when operating or when
the chassis power cord is connected to the AC Line
(mains).
Any adjustment, maintenance and repair of an opened, powered-on
instrument should be avoided as much as possible, but when necessary,
should be carried out only by a skilled person who is aware of the
hazard involved.
Supplied

Output - Channel 1 The channel 1 output connector outputs fixed (standard) waveforms to
50 MHz, user (arbitrary) and sequenced waveforms with sampling clock
to 100 MSa/s. Output impedance is 50Ω, therefore, for best
performance, the cable connected to this output should be terminated
with 50Ω. Output amplitude accuracy is calibrated when connected to a
50Ωload. If the output is connected to a different load resistance,
determine the actual amplitude using the following equation:
