Programmable arbitray function generator
Juntek PSG9080 is a 80Mhz bandwidth programmable arbitrary function/signal generator packed with features and support for Windows, Android and iPhone iOS management support.
A lot of featuers, but will it worth the money? Let’s find out.
This is one of those devices that I always had my eyes on for review. To be honest, if I didn’t had the channel and only wanted to play a bit with electronics without serious investment as I did when I started, this will be, considering the features and specs, the function generator that I would bought.
Why? Because it has 80Mhz bandwidth (sinewave), is packed with a lot of functions, is a bench programmable arbitrary function generator and for a very accessible price.
So, when Juntek contact me for review this device, I was happy to finally put my hands on this unit. Spoiler alert, my initial expectations about this equipment were confirmed.
On the back you have 2 Sync BNC’s, a USB type-B connector por PC connection, a 220V power socket, an aditional power supply socket for external power supply and a external expansion connecto where you can connect the wireless bluetooth dongle.
The front is quite complete as you expect on any bench function generator. You have the usal knob for fine tunning, a keyboard, several menu selection keys, another 2 BNC’s for sync and 2 BNC’s for signal output (2 channels).
In terms of features this what we get:
|Bandwidth||1nHz to 80Mhz|
|Vertical resolution||14 bits|
|Wave length||8192 points/channel|
|Waveform types||Sine wave, square wave, pulse wave (duty ratio, pulse width and cycle time can be precisely set), triangle wave, rising ramp, falling ramp, CMOS wave, DC level, half wave, full wave, positive step wave, Inverse staircase wave, exponential rise, exponential fall, Lorentz pulse wave, multisonic wave, random noise wave, trapezoidal pulse wave, Sinker pulse wave, and 99 sets of user-defined waveforms.|
|Square wave||1nHz to 30Mhz|
|Triangle wave||1nHz to 50Mhz|
|Total harmonic distortion||≤0.5% (@1Khz, 5Vpp)|
|Amplitude stability||± 1% ±1mVpp (@ 1kHz,>10mVpp)|
|Phase adjustment range||0°-359.9°|
|Output impedance||50Ω (typical)|
|Trigger source||Manual burst, CH2 burst, external burst (AC), external burst (DC)|
|Measure functions||Frequency, positive and negative pulse width, period, duty cycle|
|Sweep function||Sweep frequency, sweep amplitude, sweep duty|
|Sweep mode||Linear, logarithmic|
|VCO function||Frequency control, amplitude control, and duty cycle control|
In terms of usage, the interface is easy to control, has very small learning curve and is very customizable. You have a 3.5″ color TFT screen that will give you a organized information of everything that is going on.
The test I made went ok, you have the video bellow to check it out and the overall feeling while using this unit is pretty good.
To be honest and considering the price, this unit is really awesome. Juntek did a very good job on the PSG9080 and I am really glad they allow me to test it, since I could confirm the feeling I have about it.
As always, my mantra is “You get, what you pay for” but in this case, I think that you get a bit more of what you paid. It was really a nice experience to work with it.
