Description
MeasCursXDelta
ai
-Inf to +Inf Queries the difference between the cursor
positions on the x axis. Units depend upon the
cursor source waveform type. For normal time
based waveforms, the x axis is time. For FFTs
the x axis is frequency.
MeasCursYDelta
ai
-Inf to +Inf Queries the difference between the cursor
positions on the y axis. Units depend upon the
cursor source waveform type. For normal time
based waveforms, the y axis is voltage.
setMeasErrState
getMeasErrState
bo
bi
0 or 1
Determines if the measurement errors are
returned. If enabled, measurement errors are
returned at 9.99e36. If disabled,
measurement errors are returned as the status
byte.
0 = Off
1 = On

bo
bi
0 or 1
Sets or queries the state of a list of
measurements. A disabled measurement list
retains its settings.
N
is 1 to 4.
MeasList
N
Clear
bo
0 or 1
Set to clear all eight measurements from the
measurement list (
N
is 1 -4). Idle value is 0.
After setting to 1, value returns to idle.
Meas
N
Clear
bo
0 or 1
Set to clear one measurement (
N
is 1-32).
Idle value is 0. After setting to 1, value returns
to idle.
