Using Marker Peak Search And Peak Excursion; Example - HP ESA-E Series Programmer's Manual

Using Marker Peak Search and Peak
Excursion
This C programming example does the following:
• Open an HP-IB session at address 18.
• Clear the analyzer.
• Reset the analyzer.
• Set the analyzer center frequency and span to 50 MHz.
• Set the input port to the 50 MHz amplitude reference.
• Set the analyzer to single sweep mode.
• Prompt the user for the peak excursion and set them.
• Set the peak threshold to −90 dB.
• Trigger a sweep.
• Check for operation complete.
• Set the marker to the maximum peak.
• Query and read the marker frequency and amplitude.
• Close the session.

Example:

#include <stdio.h>
#include <stdlib.h>
#include <math.h>
#include <conioh>
#include <ctype.h>
#include <string.h>
#include "<visa.h>"
#define hpESA_IDN_E4401B
#define hpESA_IDN_E4411B
Visession defaultRM, viESA;
ViStatus errStatus;
ViChar cIdBuff[256] = {0};
char cEnter = 0;
int iResult = 0;
/*Set the input port to the 50 MHz amplitude reference*/
void Route50MHzSignal()
