Processing Measurement Results

Analyzing Measurement Results

information on the parameters you can analyze.

Example 7-4 shows a sample program for ceramic resonator parameter analysis using the

“OUTPCERR?” command. This program is available under the filename “ana_com.bas”

on the sample program disk.

This program performs a sweep once, uses the “OUTPCERR?” command to analyze

ceramic resonator parameters, and reads and displays the analysis results.

Lines 30 to 70 Identifies the external controller and Instrument BASIC and sets the

GPIB address.

Lines 90 to 120 Assigns the sweep center value, the sweep span value, the trace

selected for analysis, and the peak threshold the corresponding

variables Cent, Span, Ana_trc$, and Thrr, respectively.

Lines 140 to 180 Resets the Agilent 4294A, sets impedance amplitude and phase as

measurement parameters, sets the sweep center value and the sweep

span value, respectively, to Cent and Span, and specifies log Y-axis

format as display format.

Lines 190 to 250 Performs a sweep once and then performs the auto scale to

automatically set the scale parameters so that the waveforms fit on the

screen.

Lines 270 to 290 Specifies the entire sweep range as the analysis range and sets the trace

selected for analysis and the peak threshold to “Ana_trc$” and “Thrr,”

respectively.

Line 300 to 310 Executes the “OUTPCERR?” command to read analyzed parameters.

Lines 330 to 380 Displays the analysis results.
