Syntax
BOTV <numeric>[OHM|DEG|RAD|SIE|H|F|PCT]
BOTV?
Description
Sets the minimum value on the display screen in the Y axis (vertical axis) direction (the
value of the bottom of the grid).
If the difference between this minimum value and the maximum value on the display
screen in the Y axis direction (set with the "TOPV" command on page 456) is less than
10E-15 (for the log Y axis format, the ratio of the maximum value to the minimum value is
less than 5), the maximum value is automatically changed so that it becomes larger than the
value of the minimum value plus 10E-15 (for the log Y axis format, the value indicating
that the ratio of the maximum value to the minimum value is 5). Also, the width of a single
grid tick (SCALE/DIV) and the reference line value (REFERENCE VALUE) are
automatically changed so that they match with the Y axis minimum value and maximum
value setting.
For the log Y axis format, if the sign is different from the display screen maximum value
setting, the sign of the maximum value is automatically changed to the same sign as the
minimum value.
Parameters

Range
Initial value
Unit
Resolution
If the specified parameter is out of the allowable setting range, the minimum value (if the
lower limit of the range is not reached) or the maximum value (if the upper limit of the
range is exceeded) is set.

For formats other than the log Y axis format:
-1E9 to 1E9
For the log Y axis format:
-200E6 to 200E6
For formats other than the log Y axis format:
Varies depending on the measurement parameter as follows:
For other than θ: 0
For θ: -180
For the log Y axis format:
Varies depending on the measurement parameter as follows:
For |Z|, R, X, Rs, Rp: 1
For θ: 100E-6
For |Y|, G, B, D: 1E-6
For Cs, Cp: 1E-9
For Ls, Lp: 10E-6
For Q: 1E-3
Varies depending on the measurement parameter (refer to the
explanation of unit in "SCAL" on page 423).
*1
1E-15
*1.This is the minimum value (when the set value is small). The resolution
becomes larger as the set value becomes larger.
