Missing waveform readouts

Post by voltotech »

I don't succeed to have a triggered rectangular signal on the display and the waveform read-outs on. Either the signal is not triggered and floating then freq, cycle, PW and duty cycle show values or signal is triggered but instead of values there are only --- signs. I have about 15 DSO138 with f/w versions 50 and 61. Everywhere the same.
