Introduction
Hantek 1025G Arbitrary Waveform Generator has one channel of arbitrary waveform output,
12 Bits output, synchronized signal outputs, 1 channels of Counter/Frequency Measurement
inputs, 6 Bits input and external trigger input. User can edit the waveform arbitrarily by the
mouse or choose the regular waveforms such as Sine, Square, Tri-angle, Saw-tooth, TTL,
White Noise, Gauss Noise, Trapeze, Exponent, AM and FM. The parameters, such as
amplitude, frequency and offset, are also settable. The data format of Hantek 1025G is
completely compatible with that of Tektronix; it can directly read the waveform data files
produced by the Tektronix oscilloscope or Tektronix waveform editor software and redisplay
the waveform. Hantek 1025G adopts the DDS technology so that it has the advantages of
high frequency accuracy, high waveform resolution, high reliability, and wide software
support. It can widely use in the various kinds of electronics labs and it offers complete
interface for second time development to be pointlessly inserted into other auto-measuring
systems.

At the digital IO terminal on the Hantek1025G, there are 20 digital IO pins, 1 GND, 1 TRIG, 1
CTRL, 1 COUNT IN, 4 Digital In Pins and 12 Digital Out Pins.
1. Pattern Generator:
The vertical resolution of Hantek1025G is 12bits. If selected this mode, you can get the each
bit of the value by testing the digital out pins. The LSB is O0, and OB is MSB. By Logic
Analyzer, you will get a good view.
For example: Use the Hantek1025G to generate a 1 KHz, 2.00V, sine waveform. Then
connect the O0- OB to logic analyzer. And you will see the sine waveform on the logic
analyzer.
USER’S MANUAL 23

2. Programmable Output:
Select menu “Programmable output”, then the Programmable output mode works. Select
menu “Digital IO”->”Output set”, the “output set” dialog show.
USER’S MANUAL 24
Hantek1025G
By selecting one pin, that digital output pin will output high level. Otherwise, the pin will
output low level.
3. Digital Input
Select menu “Digital IO”->”Digital Input”, the following dialog show.
If you input a high level to a digital input pin, the pin on the dialog would show H;
otherwise, the pin on the dialog would show L.

3.7 Output without PC
Hantek1025G can save a waveform to its own memory and work without PC.
Open:
Select menu “Utility” -> “Open output power on”. Then the current waveform will be saved to
hardware. And the waveform will be generated every time when you connect the Hantek
1025G to power.
The Hantek 1025G is powered by USB.
Close:
If you want to clear the waveform from the hardware memory, select “Close Output Power
On”.
If you don’t want to generate the waveform which is saved in the hardware memory, connect
the “CTRL” pin end to ground before inputting power to this instrument.
USER’S MANUAL 26
Hantek1025G
3.8 Synchronized output
If you generate a waveform by software, there is a synchronized signal output from “SYNC”
terminal. The signal is square waveform, the frequency of which is equal to the waveform
you generated.
For example, if you generated a 1 KHz, sine waveform, you will also generate an 1 KHz,
square waveform simultaneously.
The waveform on CH1 is the sine waveform you generated from the “OUTPUT” BNC
terminal, and that on CH2 is the synchronized signal from “SYNC OUT” BNC terminal.
USER’S MANUAL 27
Hantek1025G
3.9 External Trigger Input
Also, you can use the external trigger input to control the Hantek 1025G.
For example, the instrument generated a waveform, and you got a waveform on oscilloscope.
Then, click the “Ext Trig” button on the interface of the software. The waveform on the
oscillograph disappeared. Now the instrument use the external trigger system, but there is no
external signal input, so the instrument stops to output waveform.
USER’S MANUAL 28
Hantek1025G
Click the “Ext Trig Mode “to switch the external trigger mode between “Fall” and “Rise”.
Select the Fall mode as example.
Input a signal which has fall edges to the “TRIGIN” pin terminal. When the Hantek 1025G
gets to the fall edge of the external signal, it begins to generate waveform.
