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.

CAT I

CAT II

CAT III

CAT IV

Secondary electrical circuits that are connected
to a wall outlet through a transformer or similar
device.

Primary electrical circuits in equipment
connected to a wall outlet via a power cord
(portable tools, household appliances, etc.)

Primary electrical circuits of heavy equipment
(fixed installations) connected directly to the
distribution panel, and feeders between the
distribution panel and outlets.

The 7075 is a multi-channel waveform generator with function generator and
arbitrary wavefor m 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 wavef orm parameter, so this waveform generator is ideal
for sim ulating a variety of signal sources and test situations.
A large LCD with touch panel provides very easy operation.

Jog Dial Entry

The Jog dial can be used to set frequency or clock frequency. When a
arbitrary waveform is selected, the clock frequency is displayed at the left
side and the output frequency can be set within parentheses.

Setting is inhibited when sweep is active
Setting is inhibited for noise or DC waveforms

All settings are stored as frequencies within the 7075. Because rpm (r/min)
and period (s) formats are converted to facilitate the internal analysis
functions, entered values and actual setting values may differ slightly, in
which case the actual setting is made as close as possible to the entered
value.

When changing a waveform, if the setting frequency exceeds the settable

range of that waveform, the maximum allowable value is used.

The Jog dial can be used to set frequency and clock frequency formats, but

not the rpm (r/min) or period (s) formats.

7.3 Description of Synchronized Operation

Up to four units can be connected via their external control terminals to
operate synchronously (as a master and three slaves). For synchronized
operation, the 7075s are connected in cascade so that all slaves are governed
by the following control signals from the master unit: RUN/STOP, MASTER
CLK and SYNC CLK.

Never turn on any slave unit before turning on the master unit. If this
occurs, the slave unit may not output the proper waveforms.
With the connections above, if the system stops at a setting made according
to "3.7.17 Setting the Total Number of Loops," the following events occur:

When the master unit is stopped:
All slave units stop. (For the offset value, the last data continues to be
output.)

When a slave unit is stopped:
Only the involved slave unit stops. No other units are affected. The
RUN/STOP key on the stopped slave unit remains lit until the master unit
stops. (For the offset value, the last data continues to be output.)

────────────────────────────────────────────────────

8.2.3 Receive and Send Protocols

Messages

Data received or sent by the GP-IB interface is called a message.
The following are the message types:

Program messages

Messages

Response messages

Command messages
Query messages

Of these, program messages are those received by the unit from the
controller, while response messages are those sent from the unit to the
controller. During addressable, program messages are those received by the
unit from the external controller, while response messages are those sent
from the unit to the controller.

(1) Program messages

Program messages can be divided into either command messages or query
messages.

Command program messages

Orders for control of the device, such as for making settings for output or
waveform output/stop or the like.

Example: When sending the messages from the personal computer to the

7075.

:OSET:AMPL 1,10.000

This message sets the amplitude of channel 1 of the 7075 to 10.000 V.

Query program messages

Orders for responses relating to the results of operation, results of self-test,
or the state of device settings.

These commands are identified by "?" at the end of their comments in "8.4
GP-IB Command Summary."

(2) Response messages

Sent in response to query program messages. After a query message sent
from the external controller has been received, a response message is
produced the moment that its syntax has been checked.

────────────────────────────────────────────────────

8.2 Operations

70

────────────────────────────────────────────────────

Command

syntax

NOTE

When no ambiguity would arise, the term "command" is henceforth used to
refer to both command and query program messages.
The 7075 accepts commands without distinction between lower case and
upper case letters. It generates response messages in the long form (when
headers are enabled) and in upper case letters.
The names of commands for the 7075 is as far as possible mnemonic.
Furthermore, all commands have a long form, and an abbreviated short form.
In command references in this manual, the short form is written in upper
case letters, and then this is continued in lower case letters so as to
constitute the long form. (Either of these forms will be accepted during
operation, but intermediate forms will not be accepted. Further, during
operation both lower case letters and upper case letters will be accepted
without distinction.)

If a command consists of more than four characters it can be truncated to
the first four characters, unless the fourth character is a vowel, in which case
the proper truncated form consists of only the first three characters.

Example
For "FILTer", either "FILTER" (the long form) or "FILT" (the short form)
will be accepted. However, any one of "FILTE", "FIL", or "FI" is wrong and
will generate an error.
For "MEMory", either "MEMORY" (the long form) or "MEM" (the short
form) will be accepted. However, any one of "MEMOR", "MEMO", or
"ME" is wrong and will generate an error.

Command

program headers

Commands must have a header, which identifies the command in question.
There are three kinds of header: simple command type, compound command
type, and common command type.

Simple command type header

The first word constitute the header.

:HEADer ON

Simple command

Compound command type header

Data

A header made up from a plurality of simple command type headers marked
off by colons.

:SYSTEM:BEEPer OFF

Query program

headers

Response

messages

Terminators

and separators

These are for commands used for interrogating the unit about the result of an
operation or about a setting.
These can be recognized as queries by a question mark appearing after the
program header. The structure of the header is identical to that of a
command program header, with "?" always being affixed to the last
command. There are queries possible in each of the three previously
described types of command form.

:HEADer?

Query program header

Response messages relating to queries are made up from header portions
(which also may be absent due to header disablement) and data portions
identical to those of program messages, and as a general rule are sent in an
identical format to the format of the program message corresponding to their
originating query.

Message terminator

A terminator is used in order to separate the transmission of one message
from another, and this terminator is not itself included in the message. On
the unit, LF, EOI (GP-IB only), or LF+EOI (GP-IB only) is used as the
message terminator. LF+EOI or CR+LF+EOI is used as the response
message terminator. (Select on the GP-IB setting screen or set by the
:COM:TERM command for RS-232C interface)

Message unit separator

A semicolon ";" is used as a message unit separator when it is desired to set
out several messages on a single line.

:SYSTEM:BEEPER ON;:SYSTEM:TIME 10,20,30

Messa

Header separator

eunitseparator

With a message which has both a header and data, a space " " is used as a
header separator to separate the header from the data. The space " " is used
by way of explanation, but it does not appear on the actual program.

:SYSTEM:BEEPER ON

Header separator

Data separator

Commas are used as data separators for separating several data items from
one another.

:SYST:TIME 10,20,30

Data separator

────────────────────────────────────────────────────

8.2 Operations

72

────────────────────────────────────────────────────

Command

tree

Data format

When multiple compound command messages are sent to the 7075, if there
is no colon (:) in the header following the semi-colon (;) separator, the
header of the latter command is considered to be the same as that before the
previous colon. (As this construction is similar to the concept of the current
directory in Unix and MS-DOS directory structures, we call the previous
header the current path.)

:SYST:TIME 10,20,30;:SYST:BEEPER ON
:SYST:TIME 10,20,30;BEEPER ON

Both examples set the internal clock to 10:20'30" and then enable the beeper.
In the first case, a colon follows the semicolon, so the current path is from
the root, and the command search in the 7075 begins at the root. In the
second case, the current path of "SYS:TIME 10,20,30" is ":SYST", so the
following ":BEEPER" command can omit ":SYST".

The 7075 uses character data, decimal data and character string data.

Character data

The first character must be alphabetic. The characters after the first character
can only be alphabetic characters, numerals, or underline characters (_). As
alphabetic characters, during sending only upper case letters are used, but
during receiving both upper case and lower case letters are permitted.

Decimal data

Decimal data values are represented in what is termed NR format.
There are three types of NR format from NR1 to NR3, and each of these can
appear as either a signed number or an unsigned number. Unsigned
numbers are taken as positive.
Further, if the accuracy of a numerical value exceeds the range with which
the 7075 can deal, it is rounded off. (5 and above is rounded up; 4 and
below is rounded down.)

NR1 format: integer data

(Examples)

NR2 format: fixed point numbers

(Examples)

NR3 format: floating point numbers

(Examples)

+15, -20, 25

NRf f orma t

+1.23, -4.56, 7.89

+1.0E-3, -2.3E+3

The term "NRf format" includes all these three formats.
When the 7075 is receiving it accepts NRf format, but when it is sending it
utilizes whichever one of the formats NR1 to NR3 is indicated in the
particular command.

Character string data

The data is composed of 7 bit ASCII characters and character string data is
enclosed within quotation marks. When the 7075 is sending, only the double
quotation mark (") is used as a quotation mark, but when receiving both this
double quotation mark and also the single quotation mark (') are accepted.
Characters which cannot be handled by the 7075 are replaced by spaces.

8.2.4 Usable Message Bytes (GP-IB)

Message bytes usable by the unit are as follows.

(1) Address command group

GTL ( Go To Local ): Enables local operation of the 7075.
SDC ( Selected Device Clear ): Sets the 7075 to initialized state.

(2) Universal command group

LLO ( Local Lock-Out ): Disables local operation of the 7075.
DCL ( Device Clear ): Sets the 7075 to initialized state.

8.2.5 LOCK (LCL) Key and Indicator (GP-IB)

(1) Status Indicator Display

The LOCK(LCL) key at the front panel lights red to indicate that the unit is
under remote control by an external device.

(2) LOCK (LCL) key

This key cancels remote control by GP-IB and actives local operation.
However, if the Local Lock-Out state has been set by the GP-IB, this key is
disabled.

8.2.6 Status Model

In its implementation of the serial polling function using service requests, the
7075 employs the status model specified by IEEE 488.2.
The term "event" refers to any phenomenon which generates a service
request.

Service request enable register (SRER)

The status byte register holds information relating to the event registers and
the output queue. It is further possible to use the service request enable
register as a mask to select the items required. If any of the bits selected by
the mask becomes 1, bit 6 (the master summary status or MSS bit) is also
set to 1, an RQS message is generated, and this generates a service request.

8.2 Operations

────────────────────────────────────────────────────

8.2.7 Status Byte Register

Each bit of the status byte is a summary (logical OR) of the event register
corresponding to that bit. Further, the status byte and each event register has
an enable register corresponding to it, and according to the setting of this
enable register (which starts off at zero when the power is turned on) it is
possible to mask the service requests originating from each event.

(1) Input buffer

The 7075 has an input buffer of 256 bytes capacity. Messages which are
received are put into this buffer and executed in order.

When more than 256 bytes of data are sent so the buffer becomes full, the
GP-IB bus enters the waiting state until buffer space becomes available.

(2) Output queue

The 7075 has an output queue of 256 bytes capacity.
Response messages are accumulated in this queue and are read out from the
controller.
The circumstances when the output queue is cleared are as listed below:

1. When a device clear is issued.

2.Whenthepoweristurnedoffandturnedonagain.

When 256 bytes of response messages have been queued, the next response
message is held in a waiting state until space becomes available. In this
condition, if data in the input buffer also exceeds 256 bytes, a query error
occurs and the output queue is cleared.

8.3 Command Reference

(1) Command Execution

Commands are loaded into the input buffer and executed in order.

(2) Response to Query

In response messages to queries, only the data portion is returned if headers
are turned off. If headers are turned on, the data is returned with a header.
In response messages, numeric data is returned in the format (NR1 to NR3)
that was used for the parameter of the specific command table.

(3) Command Reference Description

The command reference lists common commands first, followed by 7075­specific commands. The 7075-specific commands are categorized in the
following order: environment & miscellaneous settings, environment settings
