Safety Notes
This manual contains information and warnings essential for safe operation
of the product and for maintaining it in safe operating condition. Before
using the product, be sure to carefully read the following safety notes.
The following symbols in this manual indicate the relative importance of
cautions and warnings.

Safety Notes
────────────────────────────────────────────────────
CAT I Secondary electrical circuits that are connected
to a wall outlet through a transformer or similar
device.
CAT II Primary electrical circuits in equipment
connected to a wall outlet via a power cord
(portable tools, household appliances, etc.)
CAT III Primary electrical circuits of heavy equipment
(fixed installations) connected directly to the
distribution panel, and feeders between the
distribution panel and outlets.
CAT IV The circuit from the service drop to the service
entrance, then to the power meter and to the
primary overcurrent protection device.
Overvoltage Categories (CAT)
This product conforms to the safety requirements for CAT II measurement
products.
To ensure safe operation of measurement products, IEC 60664 establishes
safety standards for various electrical environments, categorized as CAT I to
CAT IV, and called overvoltage categories. These are defined as follows.
Higher-numbered categories correspond to electrical environments with
greater momentary energy, so a measurement product designed for CAT III
environments can endure greater momentary energy than one designed for
CAT II. Using a measurement product in an environment designated with a
higher-numbered category than that for which the product is rated could
result in a severe accident, and must be carefully avoided.

Notes on Use
────────────────────────────────────────────────────
DANGER To avoid electric shock, do not remove the product's cover and
panel. The internal components of the product carry high voltages
and may become very hot during operation.
WARNING Before turning the product on, make sure the source voltage
matches that indicated on the product's power connector.
Connection to an improper supply voltage may damage the product
and present an electrical hazard.
To avoid electric shock and ensure safe operation, connect the
power cable to a grounded (3-contact) outlet.
To avoid electric shock, do not allow the product to get wet, and do
not use it when your hands are wet.
Do not use the product where it may be exposed to corrosive or
combustible gases. The product may be damaged or cause an
explosion.
CAUTION To avoid damage to the product, protect it from vibration or shock during
transport and handling, and be especially careful to avoid dropping.
Do not use excessive force on the touch panel, and do not use sharp
objects that could damage the touch screen.
This product should be installed and operated indoors only, between 0
and 40 and 85% RH or less.
Do not store or use the product where it could be exposed to direct
sunlight, high temperature or humidity, or condensation. Under such
conditions, the product may be damaged and insulation may deteriorate
so that it no longer meets specifications.
This product is not designed to be entirely water- or dust-proof. To avoid
damage, do not use it in a wet or dusty environment.
If an abnormal display or other condition occurs while operating the unit,
immediately turn the power switch off, and contact your supplier or our
offices.
The top of the product normally gets hot during operation, so be careful
when touching the case.
WARNING Before using the product, make sure that the insulation on the cable is
undamaged and that no bare conductors are improperly exposed.
Using the product in such conditions could cause an electric shock,
so contact your dealer or Hioki representative for repair.

1.1 Product Overview
────────────────────────────────────────────────────
Chapter 1
Overview
1.1 Product Overview
The 7075 is a multi-channel waveform generator with function generator and
arbitrary waveform generator function. The function generator provides eight
basic waveform types, such as sine and square waves. The arbitrary
waveform output allows generating long-duration, high-quality waveforms.
Basic capabilities include 128,000-word-long memory, 10-MHz clock rate
and 16-bit resolution.
The function generator and arbitrary waveform output can be swept
according to each waveform parameter, so this waveform generator is ideal
for simulating a variety of signal sources and test situations.
A large LCD with touch panel provides very easy operation.

1.2 Features
────────────────────────────────────────────────────
1.2 Features
(1) Easy operation
Interactive operation is provided by the touch panel. Frequently used keys
are arranged on the panel for easy operation.
(2) Built-In 4-channel generator
The compact unit includes an internal 4-channel waveform generator. The
single unit can generate all signals to simulate a 3-phase motor.
(3) Independent channel operation capability
Sweep sequences can be controlled separately for each channel by rear-panel
control signals.
(4) Multiple units can be operated synchronously (providing up to 16
channels)
Up to 16 channels can be synchronously output to test multiple phenomena.
(5) Various conditions of the waveform output (frequency, amplitude,
offset, etc.) can be swept
The sweep is easily set, and by using the sequence function, complex
patterns can be output easily.
(6) Long-duration arbitrary waveforms can be generated from 128,000
words/channel memory
The 128,000-word arbitrary waveform memory allows long-duration
waveform output.
(7) 16-bit amplitude resolution
The 16-bit amplitude resolution provide high-quality waveforms.
(8) Actual waveforms can be used by downloading from the Memory
HiCorder
Waveform voltage and time axis data can be downloaded from our Memory
HiCorder and the same waveform immediately output.
(9) Waveform creation software included
Our Model 7990 WAVEFORM CREATION SOFTWARE for Windows95/NT is
provided for easy arbitrary waveform creation on a PC.

2.2 Connecting the Power Cord
────────────────────────────────────────────────────
WARNING Before turning the product on, make sure the source voltage
matches that indicated on the product's power connector.
Connection to an improper supply voltage may damage the product
and present an electrical hazard.
To avoid electric shock and ensure safe operation, connect the
power cable to a grounded (3-contact) outlet.
2.2 Connecting the Power Cord
1. Verify that the power switch of the unit is set to OFF.
2. Make sure that the power supply matches the ratings, and plug the power
cord into the power connector on the rear panel.
3. Plug the power cord into the outlet.

────────────────────────────────────────────────────
2.3 Output Terminal
────────────────────────────────────────────────────
WARNING The minimum load impedance of the analog output terminals is 40 Ω.
Avoid connecting loads with less than 40 Ω, or short-circuiting the
output, as the unit could be damaged or overheat.
CAUTION Avoid applying external voltage to the analog output terminals, as the unit
could be damaged.
NOTE
2.3 Output Terminal
Waveforms are output from the analog output terminals, with the lowest
terminal being channel 1. BNC cables can be directly connected.
To obtain optimum quality high-frequency waveform output, the load should
be terminated at 50 Ωimpedance. In this case, the waveform amplitude is
half of the value set on the 7075.
