Common Commands

*SAV (Save)

Command *SAV <register>

The *SAV command stores the current state of the analyzer in a save register. <register> is an

integer, 0 through 9, specifying which register to save the current analyzer setup.

Example 10 OUTPUT 707;"*SAV 3"

See Also *RCL (Recall)

*SRE (Service Request Enable)

Command *SRE <mask>

The *SRE command sets the Service Request Enable Register bits. By setting the *SRE,

when the event happens, you have enabled the analyzer’s interrupt capability. The scope will

then do an SRQ (service request), which is an interrupt. <mask> is an integer, 0 to 255, rep-

resenting a mask value for the bits to be enabled in the Service Request Enable Register as

shown in Table 3-5 on page 3-12.

Example This example enables a service request to be generated when a message is available in the

output queue. When a message is available, the MAV bit is high.

10 OUTPUT 707;"*SRE 16"

Query *SRE?

Returned Format <mask><NL>

Example This example places the current contents of the Service Request Enable Register in the

numeric variable, Value.

10 OUTPUT 707;"*SRE?"

The Service Request Enable Register contains a mask value for the bits to be enabled in the

Status Byte Register. A “1” in the Service Request Enable Register enables the corresponding

bit in the Status Byte Register. A “0” disables the bit.
