Specifications
• Math results can be specified as sources of another channel.
• However, you can only specify math results of channels whose numbers are smaller
than the channel that you are specifying sources for.
A uniform delay for each math operation, regardless of the number of math channels
The mean can be calculated on the math results.
Number of taps: 32 (fixed)
The calculation period changes automatically according to the DL850E/DL850EV
sample rate.
V Zoom is set in steps of 1, 2, or 5 to a value in the range of 10.00E–21 to 500.0E+18.
Upper limit: ±5.0000E+22; lower limit: ±1.0000E–23
