knob to change the parameter value; or continue pressing the
corresponding output key for two second to switch between High
Impedance and 50 Ω.
High Impedance: display HiZ.
Load: display impedance value (the default is 50 Ω and the range is 50 Ω to

Note: This setting does not actually change the instrument‟s output
impedance of 50 Ω but rather is used to maintain amplitude accuracy into
different load values.
Output ----Channel output state.
After pressing corresponding channel output control port, the current
channel can be turned on/off.
5. LAN Status Icon
The SDG1000X will show different prompt messages based on the current
network status.

front-panel operations. This chapter is divided into the following sections:
To Prepare the Generator for Use
To Adjust the Carrying Handle
To Set the Output Frequency
To Set the Output Amplitude
To Set a DC Offset Voltage
To Set the Duty Cycle of a Square Waveform
To Set the Symmetry of a Ramp Waveform
To Configure a Pulse Waveform
To Configure a Noise Waveform
To Set the DC Voltage
To Output a Built-In Arbitrary Waveform
To Use the Built-In Help System

To Prepare the Generator for Use
1. Check the list of accessories
Accessories supplied with the instrument are listed below. If anything is
missing or damaged, please contact your nearest SIGLENT Sales Office.
Quick Start Guide
Certification of compliance
A Guaranty Card
A CD (EasyWave software, Datasheet and User Manual)
A power cord designed for use in the destination country
A USB cable
2. Connect the power cord and turn on the generator
The instrument runs a short power-on self-test, which takes several seconds.
The generator powers up in the sine wave function at 1 kHz with an amplitude
of 4 V peak-to-peak (CH1). At power-on, the Output connector is disabled. To
enable the Output connector, press the Output key.
If the generator does not turn on, verify that the power cord is firmly connected
to the power socket on the rear panel (the power-line voltage is automatically
sensed at power-on). Also, make sure that the generator is connected to a
power source that is energized.
Then, verify that the generator is turned on.
Note: If the power-on self-test fails, the generator may stop and display a black
screen. For solutions, please contact the nearest SIGLENT sales office or
return the generator to SIGLENT for service.

The displayed frequency is either the power-on value or the frequency
previously selected. When changing the function, the same frequency is used
if the current value is valid for the new waveform. To set the period, press the
softkey again to switch to the period parameter
3. Input the desired frequency
Use the digital keypad to input the value directly, enter the value “20”.

The following steps describe how to change the amplitude to 8 Vpp.
1. Press the Amplitude/HighLevel softkey
The displayed amplitude is either the power-on value or the amplitude
previously selected. When changing the function, the same amplitude is used
if the current value is valid for the new waveform. To set the HighLevel for the
waveform, press the softkey again to switch to the HighLevel parameter.
2. Input the desired amplitude
Use the digital keypad to input the value directly, enter the value “8”.

To Set the DC offset
The following steps describe how to change offset to 1 Vdc.
1. Press the Offset/LowLevel softkey
The displayed offset is either the power-on value or the offset previously
selected. When changing the function, the same offset is used if the current
value is valid for the new waveform. To set the LowLevel for the waveform,
press the softkey again to switch to the LowLevel parameter.
2. Input the desired offset
Use the digital keypad to input the value directly, enter the value “1”.
Then press the corresponding softkey to select the desired unit. For example,
