User Manual ON unnecessary HF components. Coarse Selects the resolution of the VOLTS/DIV knob. Div Fine Coarse defines a 1-2-5 sequence. Fine changes the resolution to small steps between the 1X Coarse settings. 10X Selects a value according to the probe attenuation factor so as to ensure correct vertical Probe 100X readouts. Reduce bandwidth to 6MHz when using a 1X probe. 1000X Invert OFF The invert function turns the displayed waveform 180 degrees, with respect to the ground level. ON When the oscilloscope is triggered on the inverted signal, the trigger is also inverted. 2.6.2.
Math Operation The series of scope supports many math operations between analog channels waveform, including addition (+), subtraction (-), multiplication (*), division (/) and FFT. You can use cursors to measure it. The contents of this chapter: Units for Math waveform Math Operators To Adjust the Math Waveform Scale and Offset Note: If the analog channel or the math function display is truncated (waveform do not display on the screen completely), the resulting math will also be truncated.
Addition (+) or subtraction (-) V multiplication (*) V 2 division (/) None FFT dB, VRms Addition or Subtraction Math operators perform arithmetic operations - add or subtract operation - on any two analog input channels. When you select addition or subtraction, the Source A and Source B values are added or subtracted point by point, and the result is displayed. 1. Press the [Math] button on the front panel to enter the MATH function menu. 2. Press the Source 1 and Source 2 softkey respectively, and turn the Multifunctional Knob to select the source to do math operation. Analog channels (CH1~CH2) can all be used as Source 1 or source 2. 3.
Press the Operator softkey and turn the universal to select + or -to make addition or subtraction operation. The resulting math waveform is displayed on the screen and labeled with “M”. 17 / 67 Operation Unit
