Programmable output: The type of waveform output (such as sine wave, square waves, triangle wave, arbitrary wave, etc.), output time, and output sequence can be freely formulated to realize automatic work.
Firmware update in real time: Firmware upgrade can be updated at any time to fix bugs, or used for your special customization needs. Press the corresponding soft key to confirm entering the update mode, and perform a one-key firmware upgrade by connecting with the PC software.
Voltage-controlled adjustment: The frequency, amplitude and duty cycle of the output can be controlled by an external analog voltage signal to achieve voltage-controlled sweeping frequency, sweeping amplitude and sweeping duty cycle, which are widely used in industrial debugging.
Modulation function: The modulated waveforms can be output in single channel or dual channel. Modulation: The process of adding information from a signal source to the carrier to make it suitable for channel transmission. It is the technology that makes the carrier wave change with the signal.
High sampling rate: The sampling rate of up to 300MSa/s can obtain more waveform data per unit time, thus making the displayed waveform more accurate.
Personal color: In order to meet the personalized needs of customers, four color schemes for the system are provided. You can use the numeric keys and knob to select the desired system color, press the soft key save to save the selected color.
Equivalent performance dual channel output: The same or different function signals or arbitrary waveform signals can be output simultaneously; all parameters can be adjusted independently, the phase difference between the two channels is continuously adjustable from 0 to 359.9 degrees; the signal frequency can be up to 80MHz, and the output signal can be within 1MHz up to 25Vpp.
Burst function: Sine wave, square waves, saw tooth wave, or arbitrary wave can be used to generate burst signals, the number of periods is continuously adjustable between 1-1000000000.
The pulse width can be adjusted accurately: The pulse width and the pulse period time of the pulse wave are digitally and accurately adjustable, enabling a wide range of pulse waveforms to be accurately set without jitter output.
Can draw arbitrary waveform: PC software and communication protocol are provided for free, arbitrary waveforms can be drawn using the PC software; using the communication protocol can be secondary development programming; all functions of the instrument can be controlled by the PC software (The instrument can be also finished all operations without connecting to the computer.)

Arrived before the announced deadline of 1 week. The packaging is intact. The set is 100% + gift TTL bluetooth board B-91 for communication with a smartphone application. The quality of the signals corresponds to those requested by the manufacturer. Extremely easy to set up and operate. The price is lower than the quality of workmanship compared to other brands. For a home laboratory it is more than enough. I am very satisfied. I recommend !
Received, read the manual, and tested - delightful device !
It came with a little plug in Bluetooth device to use an Android phone or pad to control the PSG9080 - which would allow to move the PSG9080 off the bench and control and read it from the Android device instead of its own screen and controls.
I found that Android 7 devices worked with the app to link automatically to the Bluetooth card, but Android 11 did not work. The Bluetooth device shows as BSG045 and if I can get the pairing key for it, can possibly get the Junteks app to connect on Android version 11.
Appreciated that the PSG9070 will happily do frequency sweeping and display the envelope on a modern scope, as a way to determine frequency response curves of tuned circuits.
One thing that I want to do is make a helper device to safely present a frequency response curve onto a vintage O'scope. The helper device has to present a very high impedance to the X-sweep output from the scope of 2 Meg Ohms, convert the +250 Volt ..0 Volt triangular waveform to +5V ..-5 V waveform that the PSG9080 inputs as external VCO input. The helper device also has to wideband amplify a signal coming from the DUT, and pass it through a diode to get a low frequency (circa 38 Hz frequency response waveform to feed into the old O'scope's amplifier.). Photo of an old O'scope included..
You might think "Why bother with adapting to vintage gear?". The reason is that modern devices, especially signal generators are far easier to use than old devices, and adapting like this reveals what engineers used to have to work with. It is educational and instructive..
Thank you for a great instrument, and long may it continue to work !
