WAVEFORM GENERATOR
SIGNAL SOURCE
Internal Sweep Sequence Functions
Arbitrary Waveform Generator with Four
Independently Controllable Channels
The
7075 WAVEFORM GENERATOR
includes both
function generator and arbitrary waveform generator
capabilities. The function generator provides 8 standard
waveforms such as sine and square waves. Basic
capabilities of the custom waveform generator include
long-duration, high-quality waveform output from a
128,000-word memory, 10 MHz clock rate and 16-bit
resolution. The function generator and arbitrary waveform
output functions can be swept according to various
parameters such as frequency and amplitude, making this
waveform generator ideal for simulating multiple signal
sources for evaluation.

Even for Complex Signals, Evaluation is
Made Easy
Features
1. Multiple Channels
Four channels (7075) or two channels (7075-01) are
provided in a compact, lightweight unit. Multi-channel
evaluations such as 3-phase motor simulations can be
produced with a single device.
2. Channel-Independent Operation
Waveform selection and various settings, including
custom waveform sampling clock frequency and sweep
control can be set and activated independently for each
channel.
3. Simple Operation
Simple, direct operation is provided by a touch panel
user interface.
4. Easy to Use with Actual Waveforms
Waveforms measured with a MEMORY HiCORDER
can be downloaded to 3.5" floppy disk or GP-IB.
Amplitude and time axes data are downloaded together,
so the actual waveforms can be reconstructed.
Waveforms and settings can also be saved. The floppy
drive is compatible with 1.44-MB MS-DOS format.
5. Synchronized Drive Capability
With one unit configured as the master, up to four units
(16 channels) can be driven synchronously.
6. Timing Simulation by External Trigger
Each channel can be independently triggered by terminals
on the rear, so various timings can be simulated.
7. Bundled Waveform Creation Software
The bundled
7990
WAVEFORM CREATION
SOFTWARE creates waveforms in the Windows
™
environment on a PC. Capabilities range from custom
waveform design to processing actual waveform
simulations. Created waveforms are transferred to the
7075
by floppy disk or RS-232C interface.
8. External Control
External control can be provided through the GP-IB
interface. Waveforms from a MEMORY HiCORDER
can also be downloaded by GP-IB.

Basic Features
q
Large 128,000-Word/Channel Memory
The large arbitrary waveform memory consists of 128,000
words per channel. Even at the fastest 10 MHz clock,
12.8 ms custom waveforms can be output.
q
16-Bit Voltage Axis Resolution,
Up to 10 MHz Clock
The 16-bit resolution on the voltage axis and 10 MHz
maximum clock provide faithful reproduction of actual
waveforms and high-quality custom waveform output
capability.
Three output ranges (0.1, 1 and 10V peak) are provided.
q
Sweep Sequence Functions Installed
Frequency, amplitude and offset can be swept
simultaneously, and combinations of sweep conditions
in up to 128 steps allow easy generation of complex
signals for evaluation.
q
Eight Basic Waveforms Built In
Eight basic waveforms: sine, square, pulse, triangle,
ramp up, ramp down, noise and DC are selectable in the
function generator mode. Eight waveforms can also be
stored in the arbitrary waveform mode, allowing quick
handling of all types of waveforms.

High Performance in a Compact Package
7075 Application Functions
q
Sweep Sequence Functions
Waveform amplitude, frequency, offset
and duty cycle* can be swept
simultaneously, so multi-pattern signals
can be easily generated.
* Duty cycle setting applies only to pulse
waveforms.
• Table-style entry of up to 128 steps
• Settable step loop time
• Sequence control by external signals
• Long-duration sweep and high-speed data refresh
Sweep time of 0.01 ms to 1000 s
Maximum data refresh speed of 1
µs
Example of simultaneous amplitude
and frequency sweep setting
Output waveform example
CH1: Simultaneous sweep of amplitude
and frequency of a sine wave
CH2: Duty cycle sweep of a pulse wave
q
Trigger Functions
When Hold is enabled for a sequence loop,
the Hold can be canceled by the trigger.
Specifically, an external trigger can be
applied to each channel independently, so
variations can be imposed on the output
according to custom timing differences
between channels.
This function is useful in, for example, an
automobile ABS simulation in which
signals for the four wheels can be
controlled independently.

Output controlled by custom timing
Output timing can be controlled by
trigger input for each channel at the
external control terminals on the rear
panel.
q
Low-Pass Filter Functions
14 types of low-pass filter with 1-2-5
progression are built in.
Device testing capabilities are enhanced
by selectably filtering the test signal, such
as for noise tests.

Downloading from a
MEMORY HiCORDER
Actual measured waveforms saved in a
HIOKI
MEMORY HiCORDER can be
downloaded by floppy disk or GP-IB. All
data types are loaded, so the actual
measured waveforms are accurately
reconstructed. Other data besides the
waveform image and amplitude- and time-
axis information is downloaded, so the
regeneration process is straightforward.
q
Converts Text Data to Waveforms
Waveforms stored as CSV data can be
reconstructed on the
