With the Measurement/Storage module installed, two functions define these
operations that create mathematically altered waveforms (not pixel math):
•
Function 1 will add, subtract, or multiply the signals acquired on vertical
inputs 1 and 2, then will display the result as F1.
•
Function 2 will integrate, differentiate, or perform an FFT on the signal
acquired on input 1, input 2, or the result in F1. It will then display the
result in F2.
You can adjust the vertical range and offset of each function for ease of
viewing and measurement considerations. Each function can be displayed,
measured with cursors, stored in trace memory, or output over the interface.
For more information about using math functions 1 and 2, refer to the
Measurement/Storage Module User’s Guide .
Mask Testing
When a Measurement/Storage module is installed in the oscilloscope,
mask testing is available by pressing the
Mask Test softkey. For more
information about mask testing, refer to the Measurement/Storage Module
User’s Guide .
To use the Roll display mode
The horizontal Roll display mode causes the waveform to move across the
screen from right to left. It only operates on time base settings of 200 ms/div
and slower. If the current time base setting is faster than the 200 ms/div limit,
it will be set to that limit when entering Roll display mode.
