To Set the High-Level and Low-Level Values
You can specify a signal by setting its amplitude and dc offset values, as
described previously. Another way to set the limits of a signal is to
specify its high-level (maximum) and low-level (minimum) values. This
is typically convenient for digital applications. In the following example,
let's set the high-level to 1.0 V and the low-level to 0.0 V.
1 Press the "Ampl" softkey to select "Ampl".
2 Press the softkey again to toggle to "HiLevel".
Note that both the Ampl and Offset softkeys toggle together, to HiLevel
and LoLevel, respectively.
3 Set the "HiLevel" value.
Using the numeric keypad or the knob, select a value of "1.0 V". (If you
are using the keypad, you will need to select the unit, "V", to enter the
value.)
4 Press the "LoLevel" softkey and set the value.
Again, use the numeric keypad or the knob to enter a value of "0.0 V".
Note that these settings (high-level = "1.0 V" and low-level = "0.0 V") are
equivalent to setting an amplitude of "1.0 Vpp" and an offset of "500
mVdc".
