Arbitrary Waveform
Source (Option 1D4)
Store up to eight arbitrary
wave forms
Test your products using real-world
signals. Measure a signal in either
the time or frequency domain, then
output it via the arbitrary waveform
source. Use math functions and data
edit to obtain precisely the output
wave form you need. An arbitrary
wave form may be output once or
re peat ed ly.
Standard source types can be
op ti mized for specific applications.
For ex am ple, random noise can be
shaped to improve the effective
dynamic range of your mea sure ment.
Al ter na tive ly, you can use data edit
and math functions to create an
arbitrary wave form.
Use time capture as a digital tape
recorder, then playback captured
signals through the arbitrary wave-
form source.

Standard 2 Mbyte
Nonvolatile RAM
Use the 2 Mbyte nonvolatile RAM as
an alternative to the 3.5 inch flexible
disk drive. The memory functions as
a high-speed disk for storage of the
following information.
Instrument setup states
Trace data
User math definitions
Limit data
Time capture buffers
Agilent Instrument BASIC programs
Waterfall display data
Curve fit/synthesis tables
Data tables
Information stored in nonvolatile
RAM is retained when the power
is off.
DataLink data transfer
solution (no charge
Option 1G0)
DataLink data transfer solution, a
no charge option for new 35670A’s,
provides all hardware and software
required to transfer data from the
non-volatile RAM, standard RAM,
or floppy drive to your PC. Hardware
provided includes the 82357B GPIB
to USB converter. Software provided
includes Instrument Basic installed
on the 35670A, plus DataLink soft-
ware and I/O Libraries that are to be
installed on your computer.
