Agilent InfiniiVision 6000 Series Oscilloscopes Programmer's Guide 771

Service Request Enable Register (SRE)

Setting the Service Request Enable Register bits enable corresponding bits

in the Status Byte Register. These enabled bits can then set RQS and MSS

(bit 6) in the Status Byte Register.

Bits are set in the Service Request Enable Register using the *SRE

command and the bits that are set are read with the *SRE? query.

Example The following example sets bit 4 (MAV) and bit 5 (ESB) in the Service

Request Enable Register.

myScope.WriteString "*SRE " + CStr(CInt("&H30"))

This example uses the decimal parameter value of 48, the string returned

by CStr(CInt("&H30")), to enable the oscilloscope to generate an SRQ

interrupt under the following conditions:

• When one or more bytes in the Output Queue set bit 4 (MAV).

• When an enabled event in the Standard Event Status Register generates

a summary bit that sets bit 5 (ESB).
