Signal Generator Digital Display Pwm Pulse Frequency Duty Ratio Adjustable Square Wave Signal Generator

I ordered more than 10 one with a faulty transistor and seemed to be former in use the rest are well packed and new. Transistor output 1am MMBT3904 Silicon NPN transistor general purpose applications, 60V, 200 V, 100 V, 300 V, 300 V

The generator works, checked everything for the oscilloscope. But the seller did not send the parcel for a long time (3 weeks). I wanted to open a dispute for a refund. For this to the seller a big minus

The generator works, checked from 5 to 12 v checked less did not try, more too. Would know its input parameters, something that did not find in the description of the goods

Generator works as described from 1 Hz to 150 kHz. The output voltage (peak to peak) is the same as DC power voltage. The current drown is 25mA @ 9V and 23mA @ 5V.

Excellent product. It works great. It took 16 days to arrive in CHILE. Thanks for everything, I will definitely buy back in this store! Thank you so much!

I measured out 1,7Vpp with 20mA/5V power consumption. Works as expected.

The goods came quickly. Not yet. I did not communicate with the seller.

Very long go, quality not so compelling, function as describe. -125kHz

Everything works thanks to the seller for the fast enough delivery
