Preface
This manual provides product specifications and instructions to verify performance
of the AWG4162 Arbitrary Waveform Generator.
To prevent personal injury or damage to the instrument, consider the following
before attempting service:
The procedures in this manual should be performed only by a qualified service
person.
Read the General Safety Summary and the Service Safety Summary at the
beginning of this document.
When using this manual for servicing, be sure to follow all warnings, cautions,
and notes.
The manual consists of the following sections:
Specifications contains a description of the instrument and the characteristics
that apply to it.
Performance Verification contains procedures for confirming that the
instrument functions properly and meets warranted limits.
The procedures described in this document should be performed every 12
months or after module replacement.
If the instruments do not meet performance criteria , repair is necessary.

All specifications apply to the arbitrary function generator unless noted otherwise.
These specifications are valid under the following conditions:
The instrument must have been calibrated/adjusted at an ambient temperature
between +20 °C and +30 °C.
The instrument must be operating at an ambient temperature between 5 °C
and +50 °C.
The instrument must have had a warm-up period of at least 30 minutes.
The instrument must be in an environment with temperature, altitude, and
humidity within the operating limits described in these specifications.

Internal trigger delay0 to 100 s
Uses Direct Digital Synthesis (DDS) techniques. It is the prevailing signal generator
architecture in the industry today. This mode offers fewer waveform variations than Advanced
mode, but with excellent stability and fast re sponse to frequency change. It can switch almost
instantly between two frequencies/waveforms. Basic mode also offers a way to modulate
the signal from internal or external sources, which is essential for some types of standards
compliance testing. In this mode, the sampling clock is fixed.

In Arbitrary mode it can define different waveforms by means of a sequencer. The sequence
decides how these waveforms are generated at the outputs of the device. There are three
different kinds of waveforms that can be defined: analog waveforms, digital waveforms or mixed

Basic mode: AC Flatness test
This test verifies the flatness of a sine wave to the 1 kHz reference waveform. The
generator should be set to Basic mode operation.
