SOURce Subsystem
4.8.1. BisSourSeg
•
Function name long BisSourSeg
•
Usage
Makes basic settings such as those for CENTER, SPAN and the number of
points, collectively.
•
Argument
typedef struct {
// For Visual C++ 6.0
double dblFreq1 // Specifies a CENTER frequency or START
// frequency (Hz).
double dblFreq2 // Specifies a frequency SPAN or STOP
// frequency (Hz).
long lngFtype // Frequency type and data output by the parallel
// output port.
//
// Frequency type (The lowest bit)
// 0: for the START mode and STOP modes.
// 1: for the CENTER mode and SPAN modes.
//
// Data output by the parallel port (upper 9 bits)
// The highest bit means the data output On or Off.
// 0:OFF / 1:ON
// The next 8-bit will output data by the parallel port.
// (negative logic)
long lngFmode // The frequency mode
// (BIS_FREQ_LIN or BIS_FREQ_LOG)
// 0:LIN / 1:LOG
long lngPntN
// Specifies the number of measurement points
float sngRbw
// Specifies IF RBW (Hz)
float sngPow1 // Specifies the START output level (dBm).
float sngPow2 // Specifies the STOP output level (dBm).
float sngStime // Specifies a settling time (sec)
} SourSeg;
[IN] long lngPID
// Packet ID (specifies the value acquired
// by BisOpenPacket)
SourSeg * Stim // A structure pointer (the start of the array)
long len
// Total bytes
// (An array depth X the number of bytes
// of the structure "SourSeg")
•
Return value
0: Normal
3: The total number of points has exceeded 1601 segments.
-1: The threshold limit has been set, because one of settings in the segment ex-
ceeded the upper or lower limit.
Other: Refer to Section
•
Description
Basic settings such as those for CENTER, SPAN and the number of points are
made collectively.
However, the maximum number of total measurement points is set to 1601.
