Communication Interfaces

Computers communicate with the generator by sending and receiving messages over
an USB interface. Command word is sended and identified in the form of ASCII
character strings for users to easily control and do user-defined development.

Operations that you can do with a computer and a generator include:

 Set the generator.
 Output waveforms from the generator.

Connection:
Please connect the USB Device port of DG1022 with the corresponding USB interface
on the computer using an USB cable.

Commands Introduction

Commands Format

The commands system of DG1022 is a tree structure, and each of sub-system is
consists of a “root” keyword and multilayered keywords. The keywords are separated
by “:” and aoptional parameters are permitted to follow; “?” appeared following a
command line denotes to query this function; besides, “space” is used to divide
command and parameter.

For example:
FUNCtion:SQUare:DCYCle {<percent>|MINimum|MAXimum}
FUNCtion:SQUare:DCYCle? [MINimum|MAXimum]

FUNCtion is the root keyword of a commmand line, SQUare and DCYCle is the
second and third keyword, all of them are separated by “:”. <percent> denotes the
parameters permitted to be set by user; “?” denotes to query; the command
FUNCtion:SQUare:DCYCle and parameter are separated by “space”.

“,” is usually used to compart multiple parameters existed in one command, for
example:
DATA VOLATILE,<value>,<value>, . . .

Symbol Instruction

Following symbols are not included in commands, but whichi are usually used to assist
to explain the parameters containd in a command line.

1. Braces { }

The parameters or contents enclosed in a { } are reqired. Only one content or
parameter could be selected every time, and all the options are separated by “|”.
For example: {ON|OFF} indicateds that ON or OFF can be selected.

2. Square brackets [ ]

Some keywords or contents are enclosed by square bracket [ ], which indicates
that those parameters are optional and will be execute no matter whether been
ignored or not.
For example:
DATA:COPY <destination arb name>[,VOLATILE]
This command copys the wave from volatile memory to the specified nonvolatile
memory. Note: [,VOLATILE] may be ignored.

3. Triangle Brackets < >

An item enclosed in < > should be replaced by an effective value.
For example:
DISPlay:CONTRAST <value>
Note: <value> must be a numerical value, such as:
DISPlay:CONTRAST 25

Parameter Types

The commands contain 5 kinds of parameters, different parameters have different
setting methods.

1. Boolean Parameters

The parameters could be “OFF”, “ON” or “0”, “1”, for example:
AM:STATE {OFF|ON}
“OFF” denotes disable AM function. “On” denotes enable.

2. Consecutive Integer Parameters

The parameters could be a consecutive integer, for example:
DISPlay:CONTRAST <value>
<value> could be an integer between 0 and 31(including 0 and 31).

3. Consecutive Real Number Parameters

The parameters could be any value only in effective range and precision
permitted, for example:
FREQuency {<frequency>|MINimum|MAXimum}
As a sine wave, <frequency> should be any real number between 1uHz~20MHz.

4. Discrete Parameters

The parameters could be a cited value, for example,

MEMory:STATe:NAME? {0|1|2|3|4|5|6|7|8|9|10}
The parameter could only be 0, 1, 2, 3, 4, 5, 6. 7, 8, 9, 10.

5. ASCII Character String

The parameters should be composed of ASCII character string, for example,
DATA:COPY <destination arb name>[,VOLATILE]
<destination arb name> is a character string defined by user.

FSKey

In FSK modulation, you can configure the generator to “shift” its output frequency
between two preset frequencies (called the “carrier frequency” and the “hop
frequency”) from CH1. The output frequency that shifts from the carrier frequency to
the hop frequency is called “FSK rate”. FSK rate is determined by internal frequency
generator or signal level which is inputted from the [Ext Trig/FSK/Burst] connector on
the rear panel.

To generate a FSK waveform, you have to configure the carrier wave, choose the
modulation source, select the “hop frequency” and the FSK rate, and then enable the
FSK modulation.

DG1022 supports following FSK commands:

1. FSK:SOURce
