LN
Linear Scale
The LN command scales the amplitude (vertical graticule divisions) proportional to input voltage, without chang-
ing the reference level. The bottom graticule line represents a signal level of zero volts.
The LN command selects V mV or UV as the vertical scale, depending on the vertical scale before LN is executed.
Units other than V/DIV MV/DIV or uV/DIV can be selected by changing the reference level after executing LN.
For example, to set the scale to 3 mV/DN, specify a reference level of 30 mV
OUTPUT 718; "LN; RL 3OmV;"
Note that voltage entries are rounded to the nearest 0.1 dB. Thus, 30 mV becomes 30.16 mV which equals -17.4
LIN
The functions of the LN command and front panel 0 key are identical. (See also KSB, KSC, and KSD.)
