Remote command:
CALCulate<Chn>:LDEViation:MODE
Auto Linearity Deviation
Turns linearity deviation calculation
and (re)calculates
using
linear regression.
Remote command:
CALCulate<Chn>:LDEViation:AUTO ONCE
Tracking
Similar to
but recalculates
for every
sweep.
This checkbox is only enabled if linearity deviation is turned
Remote command:
CALCulate<Chn>:LDEViation:MODE
Slope
Slope of the linear function to which the trace is compared.
Remote command:
CALCulate<Chn>:LDEViation:SLOPe
El. Length
The electrical length is available for "Phase" traces and frequency sweeps only.
can be interpreted as a constant group delay τ and we have the
identity:
–"Slope"/360° = τ = 10

·"El. Length"/c
with "Slope" given in
°/MHz
(degrees per megahertz) and with the speed of light c =
299792458 m/s. Hence the "Slope" determines the "El. Length" and vice versa.
Remote command:
CALCulate<Chn>:LDEViation:ELENgth
Constant
Y intercept of the linear function to which the trace is compared.
Remote command:
CALCulate<Chn>:LDEViation:CONStant
