1.
Entered numbers will be rounded up before storage as
follows:
a.
Trigger Level X1 to next multiple of 20 mV
b.
Trigger Level X10 to next multiple of 200 mV
Delay/gate time to next multiple of 25.6 Fs
c.
2.
Resolution entries are rounded down to the next integer.
Refer to Table 3.10 for resolution numbers and related gate
times.
3.
Math constant Z can be set to 0. However, an error message
will result if the Math function is enabled with this value set.
4.
Set-up Memory (RAM) commands require a single-digit
suffix ranging from 0 to 9.
