scp_measure
This command measures the frequency and amplitude of the strongest signal.
Usage
int scp_measure(int instr_id, double *freq_result, double *amp_result)
instr_id
The instrument identification code of the scope card
freq_result
The measured frequency in Hertz (Hz)
amp_result
The measured amplitude in decibels (dB)
Details
The scope card must be initialized before using this command.
This command returns a 0 if executed without error; a negative number indicates an error.
Example
double freq;
double ampltd;
.
.
.
Status1 = scp_init(SCP1);
Status2 = scp_setup(SCP1, 20e6, 850e6, 1e6);
Status3 = scp_measure(SCP1, freq, ampltd);
This example shows how to measure the amplitude of the strongest signal.
