You can display statistics (mean, min, max, std dev) for these measurements and view all measurements for a source simultaneously.

3. Cursor Measurement: Press the [Cursors] button to activate cursors for precise manual measurements. You can select between X (vertical, for time/frequency) and Y (horizontal, for voltage) cursors. In Manual mode, you can move two cursors (A and B) independently to measure the difference (delta) between two points on the waveform.

The reference waveform function allows you to save a waveform and display it on the screen for comparison with live signals. Press the [REF] button to access the reference waveform menu.

• Source: Select a channel (CH1-CH4) or a saved file as the source for the reference waveform.

• SaveToRef: Capture the current waveform from the selected source and store it as a reference waveform.

• Display Adjustment: You can adjust the vertical scale (VScale) and vertical offset (VOffset) of the displayed reference waveform without changing the live channel’s settings.

• Import/Export: Import a previously saved reference waveform file (*.ref, *.bin, *.csv) from internal memory or a USB drive, or export the current reference waveform for later use.

• Clear: Remove the reference waveform from the display.

The Pass/Fail test compares a live signal to a predefined template or mask and reports if the signal falls outside the mask. Access this function via [Utility] -> Pass/Fail.

1. Enable: Turn the Pass/Fail test function on.

2. Select Source: Choose the input channel (CH1-CH4) to test.

3. Create Mask: Create a mask by defining horizontal (X Mask) and vertical (Y Mask) tolerance bands around a reference waveform.
