This chapter contains information about how to operate the Tabor
2074. Operation is divided into two general categories: basic bench
operation, and remote operation (GPIB, USB and ENET). Basic
bench operation, which is covered in this section, describes how to
operate the arbitrary waveform generator using front panel
sequences. The 2074 is supplied with ArbConnection, a PC based
software package with a graphical user interface to allow users to
program all of the functions directly. LabView drivers and a set of
SCPI commands are available for more experienced programmers.
The following paragraphs describe the various modes of operation
and give examples of how to program the Model 2074. The manual
is organized by instrument function and instructions are given in
each paragraph on how to use the function from both the front
panel and ArbConnection.
This manual is common to Models 5064, Model 1074
and Model 2074. Features and functions are described
for the Model 2074 and the variations are described in
Appendix A. The main differences are related to the
highest sampling clock rate and the output frequency. If
you purchased either Model 5064 or Model 1074, refer to
the specification list and ignore references to frequency
and sample clock limits that exceed those which are
listed in Appendix A.
The 2074 has four output channels. Although this is a four-channel
instrument, many of the commands that set parameters and
functions are shared by all other channels. For example, sample
clock and run modes can not be set separately for each channel.
On the other hand, you may program each channel to have
different function shape, amplitude and offset. Table 3-1 lists the
function
and
parameters
dependency.
The 2074 has only one sample clock source, which means that
waveform samples are clocked simultaneously on both channels.
Therefore, if you are looking to have completely separated
channels, with no correlation between the two signals, this is not
the right instrument for you. However, most applications for
multiple channels generator require phase correlation between the
outputs and this is the way the 2074 is constructed. Shared sample
clock source assures that both channels start generating signals
exactly on the same phase and, in addition, there is an assurance
that there is no jitter between the channels. Inter-channel phase
control is described later in this chapter, in the Using the Auxiliary
Functions section.
