Frequency counter? Seems to work ok using DC trigger (tested up to 300MHz) but when switching to AC it works up to about 60MHz? But when using "Display all" the frequency seems ok in AC trigger mode. (Latest jitter fix firmware. Im not sure if it behaved the same way with the "older") /Sam Image below. 300MHz/1VRMS external 50ohm load using a "T" at the scope. (Aeroflex 2023A signal generator) Will work up to 58MHz when in AC trigger mode before it fails. (as mentioned before the "display all measurements" works) |

Yes same as older FW, I have seen this and there is a Limit to the Counter Max Frequency ( on AC triggering) I see a bit higher limit, if Freq. Counter is set to Chan 2 as the DSO is triggering on CHan1 (80 MHz) (AC or DC Trigger) I see a bit higher limit, if Freq. Counter is set to EXT as the DSO is triggering on CHan1 (60 MHz) (AC or DC Trigger) |

Does any one else find the way the Invert input is implemented by Rigol as disconcerting? The DS200 just inverts the trace on the display and Not an inverting of the input, such that the trace is shown with a falling edge trigger when the Trigger is set to be a Rising edge trigger. See Pix. I have not used any other DSO, so I am asking all "Is this the Standard way to implement the INVERT feature on a DSO?" I went and Dug out my out Tek analog scope , and it applies the Trigger mode after the input is Inverted .. Is Rigol doing it different?. |

What I learned today was creating a comb of frequencies with a train of short pulses. And it was nice to see the FFT of my DS2000 shows the results. Next I will try to test a circuit(filter) with pulses and my DSO Below see 300nsec Pulses at: 1 2.5 usec period 2 5.0 usec period 3 10 usec period 4 10 usec period with more voltage 5 20 usec period with more voltage See a good Time/Frequency domain duality experiment by SignalPath Here |
