Default Startup Conditions
The following default conditions are established during power- up:
• The Request Service (RQS) bit in the status byte register is set to zero.
• All of the event registers are cleared.
• The Standard Event Status Enable Register is set to 0xFF hex.
• Service Request Enable Register is set to 0x80 hex.
• The Operation Status Enable Register is set to 0xFFFF hex.
• The Overload Event Enable Register is set to 0xFF hex.
• The Mask Test Event Enable Register is set to 0xFF hex.
You can change the default conditions using the *PSC command with a
parameter of 1 (one). When set to 1, the Standard Event Status Enable
Register is set 0x00 hex and the Service Request Enable Register is set to
0x00 hex. This prevents the Power On (PON) event from setting the SRQ
interrupt when the oscilloscope is ready to receive commands.
