Frequency SC3100 Simplified Measuring Solution Channel DCV, VPP, Frequency Measurements Waveform Viewing Simplified Triggering 2KV Input Protection Vertical & Horizontal Sweep Rates TVV = Vertical Waveform Viewing - Approx. - 2 mS TVH = Horizontal Waveform Viewing - Approx. 2 uS Automatic Waveform Viewing Delta Time & Frequency Delta Time or Delta Frequency measures the time or frequency of the intensified portion of the waveform shown on the display. Delta Vpp Measurement Delta VPP measures the peak-to-peak voltage of the intensified portion of the waveform. Delta DCV Measurments Delta DC measures a marked point on the waveform in respect to the circuit ground. Ohms/DC Current Measurements
