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” circuits points.

Before operation this instrument:

1. Ensure the instrument is configured to operate on the voltage at the power source. See
Installation Section.

2. Ensure the proper fuse is in place for the power source to operate.

3. 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 2074.

The Model 2074 is a bench-top, 2U high, half rack wide, four­channel synthesized Waveform Generator, a high performance
instrument that provides multiple and powerful functions in one
small package. The 2074 generates an array of standard
waveforms from a built-in waveform library as well as arbitrary,
sequenced and modulated waveforms. The generator outputs 16-bit
waveforms from two channels at up to 200 MS/s with different
waveform properties. The unique design provides increased

dynamic range and lower “noise floor” making it ideal for the

generation of multi-tone signals and I&Q modulation.
Sample rates up to 200 MS/s are available with memory size up to

2 Meg. All channels are synchronized to the same sampling clock
however, each channel can output a different waveform shape and
length and by designing waveforms with different length, each
channel can output different frequencies that are synchronized to
the same sample clock source.

Based entirely on digital design, the 2074 has no analog functions
resident in its hardware circuits and therefore, data has to be
downloaded to the instrument for it to start generating waveforms.
The instrument can compute and generate a number of standard
functions such as sine, square, triangle and others. Complex
waveforms can be computed in external utilities, converted to an

Figure 1-4, ArbConnection – The Pulse Composer

appropriate format and downloaded to the 2074 as waveform
coordinates. Dedicated waveform memory stores waveforms in
memory segments and allows playback of a selected waveform,
when required. The waveforms are backed up by batteries or can
be stored in a flash memory for use at a later time.

Frequency accuracy of the output waveform is determined by the
clock reference. Using the internal TCXO the reference oscillator
provides 1 ppm accuracy and stability over time and temperature. If
higher accuracy and/or stability are required, one may connect an
external reference oscillator to the rear panel input and use this
input as the reference for the 2074. Frequency may be is
programmed from the front panel with 11 digits of resolution and
with up to 14 digits from an external controller, 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 from 20 mV to 20 Vp-p into an open circuit, and 20 mV
to 10 V into 50 loads. Amplitude and offsets are completely
independent to each other and can be programmed with 4 digits of
resolution as long as the +5 V and the -5 V rail limitations (double
into open circuit) are not exceeded. The amplitude display is
calibrated to the load source, which is normally 50 . In cases
where the load difference is different, you can customize the
instrument to display the correct amplitude reading that matches
your load impedance.

Besides its normal continuous mode, the Model 2074 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
re-trigger generator with a programmable period can be used as a
replacement of an external trigger source. Triggers can be delayed
to a specific interval by a built-in trigger delay generator that has a
range of 200 ns to over 20 seconds.

The arbitrary waveform memory is comprised of a bank of 16-bit
words. Each word represents a point on the horizontal waveform
scale. Each word has a horizontal address that can range from 0 to
2 Meg and a vertical address that can range from -32767 to +32768
(16 bits). Using a high speed clocking circuit, the digital contents of
the arbitrary waveform memory is 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 many 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 and loop up to multiple
segments in user defined order. Each channel has its own
sequence generator.

The Tabor Model 2074 can be controlled from either GPIB, USB, or
LAN interfaces. The product is supplied with IVI.COM driver and
ArbConnection software. ArbConnection simulates an array of
mechanical front panels with the necessary push buttons, displays
and dials to operate the Model 2074 from a remote interface as if it
is a bench-top instrument. ArbConnection also allows on-screen
creation and editing of complex waveforms and patterns to drive the
2074 various outputs.

It is highly recommended that the user become familiar with the
2074 front panel, its basic features, functions and programming
concepts as described in this and the following chapters.

Options

Several options are available for the 2074. These are listed below.
Note that all options are factory installed and therefore, they must
be ordered with the product.

1. Option 1 - 2 Meg Waveform Memory – increases the memory
capacity from 1 Meg to 2 Meg. The 2 Meg waveform memory
option is not field installable and therefore, it must be ordered
with the product. Compare the option number below with the
number printed on your instrument to check if the 2 Meg
waveform memory option is installed in your equipment.

Identifying
Installed Options

Options must be specified at the time of your purchase. If you place
an order for an option, you may interrogate the instrument if the
option is indeed installed on your unit. The Installed Options field in
the System display shows which of the options is installed in your
instrument. Information how to operate the menus and how to
access the System menu is given in Chapter 3.

Manual Changes

Technical corrections to this manual (if any) are listed in the back of
this manual on an enclosed MANUAL CHANGES sheet.

Safety
Considerations

The Model 2074 has been manufactured according to international
safety standards. The instrument meets EN61010-1 and UL1244
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 the
instrument or when the power cord is connected to the
mains.

1-8

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
Accessories

The instrument is supplied with a CD that includes the User Manual,
ArbConnection and IVI engine and driver.

The instrument is supplied with a power cord and a CD which
contains ArbConnection, manual, IVI driver and supporting files.
USB, LAN and synchronization cables and a service manual are
available upon request.

Specifications

Instrument specifications are listed in Appendix A. These
specifications are the performance standards or limits against which
the instrument is tested. Specifications apply under the following
conditions: output terminated into 50 after 30 minutes of warm up
time, and within a temperature range of 20 oC to 30 oC.
Specifications outside this range are degraded by 0.1 % per oC.

Functional
Description

A detailed functional description is given in the following
paragraphs. The description is divided into logical groups: Front
panel input and output connectors, rear panel input and output
connectors, operating modes, output type, output state,
synchronization, and front panel indicators.

Front Panel
Connectors and
Indicators

The Model 2074 has 3 BNC connectors on its front panel: two main
outputs and one SYNC output. Each connector on the front panel
has an LED associated with it, indicating when the output is active
(LED on), or when inactive (LED off). The function of each of the
front panel connectors is described in the following paragraphs.

Main Output – CH1,
CH2, CH3 and CH4

The main output connectors generate fixed (standard) waveforms to
80 MHz, user (arbitrary), sequenced and modulated waveforms.
The arbitrary and sequenced waveforms are sampled with sampling
clock rate to 200 MS/s. Output source impedance is 50 , hence
the cable connected to this output should be terminated with 50
load resistance. If the output is connected to a different load
resistance, determine the actual amplitude from the following
equation:
