1.4 Prepare Instrument for Use

This section describes basic procedures to help you get started quickly with the instrument. Prepare Instrument for Use Connect the power cord as desired. Turn the instrument on by pressing the power switch in the lower left corner of front panel. The instrument's default function is a 1 kHz, 200 mVpp sine wave. At power-on, the channel output connectors are disabled. To enable output on a channel connector, press the key above the channel connector and then press the Output button. If the instrument does not turn on, verify that the power cord is firmly connected (power-line voltage is automatically sensed at power-on). Also make sure that the instrument is connected to an energized power source.
Power Switch:
To turn off the instrument, please press power switch. Attention: After turning on, the process of system initialization will take 1~2 minutes; if you turn it off before the initialization is done, the next time you turn it on, it will prompt that the system is not properly shut-down. This is necessary to have the system restorable when it collapses, like the "safe mode" of Windows.
First, press F1, the device will be restart. If not, press F2 to recover the system, the system will be recovered to the factory default setting. If not, contact the customer service to get new recover partition program, and press F3 to update the recover partition.

2.4 Remote Control

The device can communicate with PC by USB port. The software on the PC can create more waves data and carry out the operation for waveform signal at the same time.

3.1 Output Configuration

This section describes output channel configuration. Many commands associated with output configuration start with SOURce1: or SOURce2: to indicate a certain channel. User can’t omit.
Output Function
The instrument includes six standard waveforms: sine, square, ramp, pulse, noise and Harmonic. There are also nine built-in arbitrary waveforms, and you can create custom waveforms with the embedded waveform editor.
The table below shows which functions are allowed (•) with modulation, sweep, and burst.
Selecting a function that is not allowed with a modulation or mode disables the modulation or mode.
(a) Gated burst only
Frequency Limitations: Changing functions may change the frequency to meet the new
function's frequency limits.
Amplitude and offset cannot combine to exceed the instrument’s capability. The one you set
last may be changed to stay within limits.
You may protect a device under test (DUT) by specifying upper and lower output voltage limits. Front Panel

Output Frequency
The output frequency range depends on the function (default frequency 1 kHz for all functions). Please refer to Appendix B.
HDG2000 Series Arbitrary Waveform Generator 26
Features and Function
Frequency Limitations: Changing functions may change the frequency to meet the new
function's frequency limits.
Burst Limitation: For internally-triggered bursts, the minimum frequency is 1 Hz. Duty Cycle Limitations: For Square and Pulse, Duty Cycle is limited by the 16ns minimum pulse
width specification. For example, at 1 kHz, Duty Cycle may be set as low as 0.01%, because that would result in a pulse width of 100 ns. At 1 MHz, the minimum Duty Cycle is 1.6%, and at 10 MHz it is 16%. Changing to a frequency that cannotproduce the current duty cycle will adjust the duty cycle to meet the minimum pulse width specification.

Output Amplitude
The default amplitude is 200mVpp for all functions. Offset Voltage Limitations: The relationship between amplitude and offset is shown below.
Vpp < 2(Vmax – |Voffset|)
Setting the high and low levels also sets the waveform amplitude and offset. For example, if you
set the high level to +2 V and the low level to -1 V, the resulting amplitude is 3 Vpp, with a -500 mV offset.
A DC signal's output level is controlled by the offset voltage (DC Offset Voltage). The DC level
may be between ±10 V.
SCPI:
SOURce<n>:VOLTage <amplitude>|MINimum|MAXimum
DC Offset Voltage
The default offset is 0 V for all functions. Limits Due to Amplitude: The relationship between offset voltage and output amplitude is shown
below. The peak output voltage (DC plus AC) cannot exceed the instrument output rating.
Setting the high and low levels also sets the waveform amplitude and offset. For example, if you
set the high level to +2 V and the low level to -3 V, the resulting amplitude is 5 Vpp, with a -500 mV offset.

Duty Cycle (Square Waves)
A square wave’s duty cycle is the fraction of time per cycle that the waveform is at a high level.
(See Pulse Waveforms for pulse duty cycle details.)
HDG2000 Series Arbitrary Waveform Generator 27
Features and Function
20% Duty Cycle 80% Duty Cycle
Duty Cycle: 0.001% to 99.996% at low frequencies; range reduced at higher frequency. Stored
in volatile memory; default 50%.

Symmetry (Ramp Waves)
Applies to ramp waves only. Symmetry represents the fraction of each cycle that the ramp wave is rising.
0% Symmetry 100% Symmetry
The symmetry (default 50%) is stored in volatile memory; and is remembered when you change
to and from other waveforms.
When ramp is the modulating waveform for AM, FM, PM, or PWM, the symmetry setting does
not apply.

Features and Function
Voltage Autoranging
Autoranging is enabled by default and the instrument selects optimal attenuator settings.
Output Control
By default, channel output is disabled at power on to protect other equipment. To enable a channel's output, see below. When channel output is enabled, the corresponding channel button is lit.
Front Panel:
CH1=CH2: The output signal of CH1 is the same as the output signal of CH2. CH1+CH2: When thisbutton is on, the output signal of current channel will be the superposition
of CH1 and CH2.
SCPI: OUTPut<n> ON|OFF OUTPut<n>?
Sync Output Signal
A sync output is provided on the front-panel Sync connector. All of the standard output functions (except DC and noise) have an associated Sync signal. For applications where you may not want to output the Sync signal, you can disable the Sync connector (Trig Menu->Syns->OFF). The
Sync signal may be derived from either output channel in the instrument. General Behavior
By default, the Sync signal is derived from channel 1 and is routed to the Sync connector
(enabled).
When the Sync signal is disabled, the output level on the Sync connector is at a logic "low." For sine, pulse, ramp, square, and triangle waves, the Sync signal is a square wave that is
"high" in the first half of the cycle and "low" in the last half.
The amplitude of Sync signal is not adjustable and fixed at TTL level.
