Re: DSO Quad bandwidth

Channels A & B can simultaneously display 3.546Mhz square waves (which is 10% of the Max sample rate of 36MS/s) with reasonable shape. I have tested that just yesterday using an HP signal generator, a LeCroy scope an the DSO Quad. I must confirm that a 5Vpp square wave is altered as low as 1 MHz. A...

DSO features checkup

Hi there. Just today I have managed a small checkup of my brand-new DSO Quad, testing it with some signals and a pro scope. Well, I have connected a HP signal generator 0 dbm (sine wave approx 0.5Vpp) on a 50 Ohms load, together with the Quad (ch-A) and a LeCroy scope (5GHz bandwidth). So far so wel...

The knobs aren't practical: they are too small and I have difficulty to press them. Over that, to scan the various functions, you have to shift the knob left or right. Now, why ...
