1. GENERAL INFORMATION

Dear customer,
thank you very much for choosing our product.
In the following, we will introduce you to what to observe while starting up
and using this product.
Should you encounter any unexpected problems during use, please do not
hesitate to contact us.

The PSG9080 function/arbitrary waveform generator can output basic
waveforms (sine wave, square wave, triangle wave, pulse wave and custom
waveforms) from one of the channels individually or both channels simul­taneously. At start-up, the two channels are configured to output a sine
waveform with a frequency of 10kHz and an amplitude of 5Vpp by default.
Users can configure the unit to output dierent basic waveforms.

The PSG9080 has these functions: Amplitude, frequency, phase modulati­on, amplitude shi keying, frequency shi keying, phase-shi keying, pulse
width modulation and burst function. It can measure the frequency, period
and length of input signals and count the periods. It also has a sampling
mode and a voltage control mode.

The button layout and 3.5" colour LCD are intuitive and easy to use. You
can save several settings in groups so you can load them quickly. The
menu can be set in German, English and French.

2. SAFETY INSTRUCTIONS

Please observe the following safety instructions before operating the unit

in order to avoid damage to the unit and the connected devices, as well
as injuries!

The unit is operated with a dangerous voltage,
Never open the casing when it is connected to the power supply.
There is a risk of electric shock!

To avoid short-circuiting or electric shock, only use a suitable mains
cable.

Prevent electrostatic discharges.

Do not supply power to the unit if any connections, wires
or components are exposed.

Do not operate if there is suspected failure or damage to the unit.

Do not operate the unit without covers or with screens removed.

Overvoltages, e.g. from a lightning strike, can damage the unit and cause
electric shocks.

Never use the unit in humid, very dusty environments or near open fire or
chemicals.

Operate the unit only at an ambient temperature between 10 °C and
50°C.

Make sure that the unit is suiciently ventilated during operation to avoid
overheating. Do not block the ventilation slots or insert any objects.

Check the unit when unpacking it for the first time and before operating
it. If there is any damage to the unit, please contact your supplier or us
directly.

4. FUNCTION KEYS

The function keys (front side no. 8):

• SYS: The system settings key. It is used to quickly switch between the main menu

and the system settings.

- Press this button to open the settings menu and then press the menu button Page
to move to the next page. Press the menu buttons to select one of the setting
options such as Clear Memory, Sound, Brightness, Language, Built-in Wave
Number, Custom Wave Number, Waveform Loading Method, Synchronization,
Factory Default, System Colour and other items.

For more product information:
Press the SYS button to get the unit information including model and serial
number.

- Press SHIFT + SYS to quickly enter the system help function.

• MOD: The modulation key. It is used to quickly switch between the main menu and

the modulation menu.

- Press this key to open the modulation menu. Here, press the TYPE menu key to
switch between the functions amplitude modulation, frequency modulation, phase
modulation, ASK, FSK, PSK, PWM and burst.

- Press SHIFT + MOD to quickly call up the burst function.

• MEAS: The measuring mode button. It is used to quickly switch between the main

menu and the measurement mode menu.

- Press MEAS and the CNTR. and MEAS. Menu buttons in the measuring mode

menu to switch between the measuring and counting functions.

- Press SHIFT + MEAS to quickly switch to the count function.

• LOAD: The load button. It is used to call up the parameters of the memory loca-

tions.

-Use the numeric keypad to select the position to load, then press LOAD to quickly
load the parameters of the desired position.

- Press SHIFT + LOAD to quickly save the parameters.

• SWEEP: The sweep key. It is used to quickly switch between the main menu and the

sweep mode menu.

- Press SWEEP to enter the sweep menu and press FUNC to switch between fre­quency sweep, amplitude sweep and duty cycle sweep.

• VCO: The VCO key is used to switch between the main menu and the voltage control

menu.

- Press VCO to enter the voltage control menu and press the FUNC menu key to
switch between the frequency control, amplitude control and duty cycle control
functions.

• FUNC: The function key. It is used to quickly switch between the main menu and

the programming mode.

- Press FUNC to enter programming mode. Press the MODE menu button to switch
between Normal Mode and Debug Mode.

• Button: The Home button.

- Press the -button to return to the standard screen.

- Press and hold to quickly save the data to the M00 position.

1.: The menu buttons display the operation menu of the currently selected function.

2.: The current finger cursor is on the CH1 interface, this means that the currently selected

channel is CH1 and the change of parameters is only valid for this channel.
By pressing the CH2 button, the finger cursor can be moved to the CH2 interface, now the
parameters for channel CH2 can be set

3.: The current channel status shows the on/o status of the current channels. ON indicates
that the channel output is on and OFF indicates that the channel output is o. With the
channel control keys CH1 and CH2, the respective channel can be switched on or o. Press

the channel control button OUT to switch the output status of CH1 and CH2 on or o simul-

taneously.

4.: Phase shows the phase-shi of the current waveform of channel 2, in relation to the wave
output at channel 1. No phase-shi can be set on channel 1. Aer pressing the correspon­ding menu key, you can use the direction keys to select the value and the rotary knob to
change the parameter.
You can also use the numeric keypad to set the phase-shi.

5.: The waveform display shows the currently set waveform of the channel.
By pressing the Wave menu button, you can change the waveform using the rotary knob or
the numeric keypad.
