Curve Fit Commands 5-91
SR785 Dynamic Signal Analyzer
Curve Fit Commands
EFIT d
The EFIT command starts the curve fit calculation for display d. The fit
parameters will be stored in curve table 1.
Display d must be a non-waterfall FFT or Swept-Sine measurement with a
frequency x-axis.
ESYN i,d
The ESYN command synthesizes the parameters in one of the two curve tables
and displays the result. The parameter i specifies curve table 1 (0) or curve table
2 (1). The parameter d specifies the display on which the result will appear:
Display A (0) or Display B(1).
ENPL (?) {,j}
The ENPL command sets (queries) the number of poles in the fitting function.
The parameter j is the number of poles, between 0 and 20.
ENZE (?) {,j}
The ENZE command sets (queries) the number of zeros in the fitting function.
The parameter j is the number of zeros, between 0 and 20.
EWTU (?) {,j}
The EWTU command sets (queries) the type of weighting used for fitting.The
parameter j specifies Uniform (0), Coherence (1), or User (2).
EWTT (?) {,j}
The EWTT command sets (queries) the trace which will be used if user
weighting is selected..The parameter j is the trace number (1-5).
ERNG (?) d {,i,j}
The ERNG command sets (queries) the fit range. The parameter d is the display
number. The parameters i and j are the starting and stopping bin numbers for the
fit range.
EDLY (?) i {,x}
The EDLY command sets (queries) the delay value associated with one of the
curve tables. The parameter i selects curve table 1 (0) or curve table 2 (1) The
parameter x is the delay in seconds.
EFSC (?) i {,x}
The EFSC command sets (queries) the frequency scaling for one of the curve
tables. The parameter i selects curve table 1 (0) or curve table 2 (1) The
parameter x is the frequency scaling value.
