FUNCTION REFERENCE 5 - 29
DIGITAL MODE
Description:
The yellow ANALOG key is used to switch from the analog mode to the digital
mode and back at any time. The signal acquisition and display functions of both
operating modes are very similar. However, the nature of the signal used or the
choice of the measurement may determine when it is best to use the digital mode.
Digital storage is used for the following:
• recording of single events, or very low frequencies
• pretrigger and posttrigger view
• glitch triggering
• saving, recalling and comparing multiple traces
• automatic measurements
• signal mathematics
• signal analysis
• making hard copies (plot/print)
• digital mode offers the convenience of the auto range function for the vertical
channels and the main time base.
The same waveform is usually displayed in the same manner, regardless of the
operating mode selected. However, some functions are not implemented in both
modes. In the analog mode, for instance, no ‘pretrigger’ information can be made
visible.
If switching from one mode to another results in an unsatisfactory display, press
the yellow key once more to return to the previous situation.
Key sequence:
Toggle switch to switch between analog mode and digital
mode.
