gen_srq.c Sample Program
/* gen_srq.c */
/*
* This example programs initializes the Agilent 86100 scope, runs an
* autoscale, then generates and responds to a Service Request from the
* scope. The program assumes an Agilent 86100 at address 7, an interface card
* at interface select code 7, and a signal source attached to channel 1.

* Function name: initialize
* Parameters: none
* Return value: none
* Description: This routine initializes the analyzer for proper acquisition of data.
* The instrument is reset to a known state and the interface is cleared.
* System headers are turned off to allow faster throughput and immediate access
* to the data values requested by queries. The analyzer performs an autoscale to acquire waveform data.

/*
* Function name: setup_SRQ
* Parameters: none
* Return value: none
* Description: This routine initializes the device to generate Service
* Requests. It sets the Service Request Enable Register Event Status Bit
* and the Standard Event Status Enable Register to allow SRQs on Command
* or Query errors.
